TiO2 exists naturally in three crystalline forms: anatase, rutile, brookite, and TiO2 (B). These polymorphs exhibit different properties and consequently different photocatalytic performances. This paper aims to clarify the differences between titanium dioxide polymorphs, and the differences in homophase, biphase, and triphase properties in various photocatalytic applications. However, homophase TiO2 has various disadvantages such as high recombination rates and low adsorption capacity. Meanwhile, TiO2 heterophase can effectively stimulate electron transfer from one phase to another causing su

Titanium dioxide (TiO2) polymorphs have recently gained a lot of attention in dye-sensitized solar cells (DSSCs). The brookite polymorph, among other TiO2 polymorphs, is now becoming the focus of research in DSSC applications, despite the difficulties in obtaining it as a pure phase experimentally. The current theoretical study used different nonmetals (C, S and N) and (C-S, C-N and S-N) as dopants and co-dopants, respectively, to investigate the effects of mono-doping and co-doping on the electronic, structural, and optical structure properties of (210) TiO2 brookite surfaces, which is the mo

Abstract TiO2 has tremendously drawn the attention of researchers from the photocatalytic to photovoltaic groups. To explore further avenues of applications, it is important to understand various properties and the phase transformations of TiO2 polymorphs at ambient conditions. The detailed study on the phase transitions (pressure induced) of the low-pressure polymorphs (rutile, anatase, brookite and columbite) of TiO2 is surprisingly missing in the literature.

Natural titanium dioxide (TiO2) occurs in three distinct polymorphs (rutile, anatase, and brookite). Currently, TiO2 gained the attention of several researchers around the world. TiO2 is used in several applications because of its excellent properties (structural, optical, electrical, chemical, non toxic, etc.). Thus, the applications are influenced by its surface, size, morphology, and crystal phase. TiO2 as photocatalyst is widely used in energy and eco-friendly applications involving water purification, hydrogen production, phenol degradation, etc. The novelty of the present chapter lies in explaining the recently reported methods that are used to synthesize TiO2 nanoparticles, such as sol-gel, hydrothermal, precipitation, etc. The different properties of TiO2 are also provided in this chapter.

Recently, the surface structure effect on photocatalytic activity has gathered increasing attention due to its reported influence on the charge carrier trapping and separation. Detailed control over the surface structure can be achieved by exposing the specific crystal facets. As a result, the photogenerated electrons and holes can be effectively separated between the different facets of semiconductor crystals. TiO2 is the most studied photocatalyst, with the particles exposing {0 0 1}, {1 0 0}, {1 0 1}, {1 1 0}, {1 1 1}, and {1 0 5} crystal facets. The performed studies have shown that the efficiency of the photocatalytic process strongly depends on the nature of the crystal facet exposed at the photocatalyst surface. In this regard, this chapter focuses on the comparison of possible surface-related parameters and photocatalytic activity of anatase, rutile, and brookite polymorphs with exposed different crystal facets. Particularly, computational data on their different possible surface structures are summarized, focusing on the geometry, energy, and possible reconstructions. This is followed by the general description of the hypothetical Wulff constructions and existing stabilization/synthesis strategies. Such an approach could help to further design, simulate, and optimize photocatalyst surface for efficient photoreduction and photooxidation processes.

TiO2 has excellent photoelectrochemical properties, which makes its suitable for photoanode applications. TiO2 is widely utilized as semiconductor for dye-sensitized photoanode owing to its excellent stability and availability. The brookite polymorph of TiO2 has been suggested to demonstrate better photocatalytic properties. In this work, we studied the adsorption of polyenediphenyl-aniline dyes on (TiO2) n = 8, 68 brookite clusters using density functional theory (DFT). We report our results on the UV–Vis absorption spectra of the dyes and dyes adsorbed on TiO2 clusters, adsorption energies of the dyes adsorbed on TiO2 clusters, electronic density of states and projected electronic density of states of the dyes adsorbed on TiO2 complex, and electron density of the main molecular orbitals involved in photoexcitation for dye-sensitized solar cells application. The calculated adsorption energies of D5@(TiO2)68, D7@(TiO2)68, D9@(TiO2)68, and D11@(TiO2)68 are 4.84, 4.78, 4.66 and 4.92 eV, respectively. The results of the adsorption energies are in the order D11@(TiO2)8 &gt; D9@(TiO2)8 &gt; D7@(TiO2)8 &gt; D5@(TiO2)8 and D11@ (TiO2)68 &gt; D5@ (TiO2)68 &gt; D7@ (TiO2)68 &gt; D9@ (TiO2)68. This implies that D11 dye molecule reacts more strongly with (TiO2)8 and (TiO2)68 brookite clusters than the other corresponding dye molecules.

Since the water splitting breakthrough using semiconductor reported in 1972, titanium dioxide (TiO2) has been extensively investigated as a promising material used in broad range of research areas. TiO2 is a transition metal oxide semiconductor with three distinct polymorph crystalline structures. With that alone TiO2 established remarkable performance as photocatalyst for organic photodegradation in the irradiation of UV. However, improvement on the light absorption properties that support the excellent photocatalytic activity still needs to be pursued for wider environmental application. In this book chapter, the limitations of TiO2 as photocatalyst were discussed especially in the industrial wastewater treatment application. The strategies in overcoming the limitation by TiO2 morphology and surface modification were also presented. The modified TiO2 nanomaterials proves to have excellent photocatalytic activity in dyes (Rhodamine B, Methyl Orange and Methylene Blue) as representative of organic pollutant degradation and Cu (II) reduction as representative of inorganic pollutant.

The dioxides of titanium (TiO2), manganese (MnO2), and zirconium (ZrO2) are important materials because of their technological uses. TiO2 is used mainly as white pigment. Because of its semiconducting properties, TiO2, in its nanomaterial form, is also used as an active component of photocells and photocatalysis for self-cleaning glasses and cements . MnO2 is used primarily in electrode materials. ZrO2 is used in refractory ceramics, abrasive materials, and stabilized zirconia as ionic conductive materials stable at high temperature. Many of these properties are, of course, dependent on particle size and shape (§ Chap. 1). Dioxides of other tetravalent elements with interesting properties have been studied elsewhere in this book, especially VO2, which exhibits a metal–isolator transition at 68°C, used, for instance, in optoelectronics (§ 4.1.5), and silica, SiO2 (§ 4.1.4), which is likely the most ubiquitous solid for many applications and uses. Aqueous chemistry is of major interest in synthesizing these oxides in the form of nanoparticles from inorganic salts and under simple, cheap, and envi­ronmental friendly conditions. However, as the tetravalent elements have re­stricted solubility in water (§ 2.2), metal–organic compounds such as titanium and zirconium alkoxides are frequently used in alcoholic solution as precursors for the synthesis of TiO2 and ZrO2 nanoparticles. An overview of the conversion of alkoxides into oxides is indicated about silica formation (§ 4.1.4), and since well-documented works have already been published, these compounds are not considered here. The crystal structures of most MO2 dioxides are of TiO2 rutile type for hexacoordinated cations (e.g., Ti, V, Cr, Mn, Mo, W, Sn, Pb) and CaF2 fluorite type for octacoordinated, larger cations (e.g., Zr, Ce), but polymorphism is common. Some dioxides of elements such as chromium and tin form only one crystal­line phase. So, hydrolysis of SnCl4 or acidification of stannate [Sn(OH)6]2− leads both to the same rutile-type phase, cassiterite, SnO2. Many other dioxides are polymorphic, especially TiO2, which exists in three main crystal phases: anatase, brookite, and rutile; and MnO2, which gives rise to a largely diversified crystal chemistry.

Abstract Resources to search for genomic variation have rapidly expanded with availability of the genomic sequence, development of fluorescence-based genomic hybridization in analysis of chromosomes, and particularly through availability of microarray technologies. Comparative genomic hybridization using arrayed Bac clones with large inserts (approximately 170 kb) of human genomic DNA has been particularly informative. Structural genomic information is also becoming more intensely studied through use of oligonucleotide arrays and single nucleotide polymorphism (SNP) arrays (described below). One of the most surprising discoveries in human genome research between 2005 and 2007 relates to the extent of copy number variation (CNV) of large genomic segments. In establishing the role of CNVs in genetic disease, it is particularly important to distinguish between normal variations and disease-causing variations. The application of extended SNP data and of microarray data to analysis of human genetic disease requires that background informa- tion be gathered to determine the extent of normal variation in the genome in that population.

Abstract The use of molecular markers to investigate the population structure of endangered or threatened species has become a key component in the genetic management of endangered species (see chapter 1). The identification of variable genetic loci has allowed the analysis of DNA sequence data to become one of the most useful measures of genetic differentiation, genetic variability, and evolutionary related¬ ness for conservation-oriented analysis at or below the species level (Wayne and Jenks, 1991; Wenink et al. 1993; Gottelli et al., 1994; Rosel et al., 1994; Taberlet and Bouvet, 1994; Taylor et al., 1994). In addition, the development of PCR (polymerase chain reaction) has allowed specific regions of the genome to be quickly isolated and amplified, so that the products of this relatively simple procedure can be readily sequenced (Saiki et al., 1988). The use of PCR technology is also advantageous because it provides a way to access DNA from a wide variety of sample sources including skin, hair, and feces which allows researchers to use noninvasive sampling methods (Karesh et al., 1987; Hoss et al., 1992; see chapter 18). With increased use of remote sampling, researchers can greatly increase the sample size of their studies, thereby increasing the strength of their analyses. However, with increased sample sizes (often hundreds of individuals), the task of generating DNA sequences from every individual in the study becomes labor-intensive, time-consuming, and costly. To facilitate the identifica¬ tion of DNA sequence genotypes in a more efficient manner, a number of DNA screening techniques have been developed that allow one to distinguish sequence differences among individuals without having to sequence each individual directly. Among the range of techniques that are available, PCR-SSCP (polymerase chain reaction combined with the analysis of single-stranded conformation poly¬ morphisms) has emerged as a favored technique for screening DNA sequences in a wide variety of applications in molecular biology (Desgeorges et al., 1993; Hunter et al., 1993; Pietravalle et al., 1994).
