Abstract:

This work investigates the correlation of structural and photovoltaic properties of dyes used in dye-sensitized solar cells. Experimental methods, including ultraviolet-visible spectroscopy, fluorescence spectroscopy, cyclic voltammetry and electrochemical impedance spectroscopy are employed to study optical and electrochemical properties of dye molecules. Computational methods, including density functional theory and time-dependent density functional theory, are used to validate and predict the optical and electronic properties of dye molecules, in their isolated state and once embedded into

Abstract:

We have investigated the nonlinear optical properties, including the optical limiting behaviour for five different concentrations of laccaic acid dye in solution and a thin film obtained through doping in poly (methyl methacrylate) (PMMA) polymer. The experiments were performed by using single beam Z-scan technique at 532 nm with 10 ns, 10 Hz Nd:YAG laser pulses excitation. From the open-aperture Z-scan data, we derived that the laccaic dye samples exhibit strong two photon absorption (2PA). The nonlinear refractive index was determined through the closed aperture Z-scan data. The estimated ab

Interfaces between semiconductors and adsorbed molecules form a central area of research in surface science, occurring in many different contexts. One such application is the so-called Dye-Sensitized Solar Cell (DSSC) where the nanostructured dye-semiconductor interface is of special interest, as this is where the most important ultrafast electron transfer process takes place. In this thesis, structural and electronic aspects of these interfaces have been studied theoretically using quantum chemical computations applied to realistic dye-semiconductor systems.

Abstract:

<p> Acid Yellow 25 (AY25) is used in the textile industry for dyeing of natural fibers as well as synthetic fibers. To a lesser extent, it is also used as a coloring agent in paints, inks, plastics, and leather. Effluents from such industries are major sources of water pollution. Dyes in wastewater are difficult and costly to remove since they are stable to oxidizing agents and light. Hence, it is important to find simple, efficient, and inexpensive ways to remove the dyes from wastewater. The objective of this study is to determine the suitability of chitin extracted from waste crab legs as a

The photocatalyst TiO2 was prepared by the sol-gel method, including hydrolysis, condensation and calcination procedures. A series of Pt/TiO2 catalysts was synthesized by ‘‘pH-adjusting’’ and “Pt-loading” aiming to evaluate the effect of pH value of sol and Pt incorporation on their crystalline phase, crystalline size and catalytic properties. The calcined photocatalysts were characterized by FE-SEM、XRD、BET and PL analysis, and applied in photocatalytic degr

碩士<br>崑山科技大學<br>光電工程研究所<br>102<br>In this study, decanoic acid (C10), lauric acid (C12), myristic acid (C14), and palmitic acid (C16) were used as the surfactants for preparing the titanium dioxide precursors, which were then subjected to be hydrothermallized at 160℃and calcined at 450℃ to fabricate mesoporous TiO2 microspheres. The properties of TiO2 precursors and microspheres and their performances of assembled dye sensitized solar cells (DSSCs) were investigated. X-ray diffraction and electron microscopy analysis indicated an amorphous structure of the wormhole-like appearance of the titan

Among the existing strategies, semiconductor photocatalysis is highly expected to be an ideal “green” technology. It has been widely applied in the field of environmental pollution protection and energy conversion. How to effectively deal with dye wastewater has been attract most of attention from all over the world. In 1972, TiO2 photocatalyst

Abstract:

The removal of Safranin-O dye from water by using activated red mud was studied in batch equilibrium technique. The effect of initial concentration, adsorbent dose, pH and contact time on the adsorption were investigated. The removal of safranin-O was expressed with Langmuir and Freundlich isotherm. The characterization and mechanism of adsorption of Safranin-O on ARM was studied using instrumental technique like SEM, XRD and FTIR. With gradual increase in pH the percentage of removal was found to be increase gradually and maximum removal was obtained at pH 8. The adsorption kinetic study show

博士<br>輔仁大學<br>化學系<br>93<br>The annual global demand for adipic acid exceeds 2.2x109 Kg, which is primarily used in production of nylon-6,6. Industrial production of adipic acid is a premier example of synthetic methodology used on a mass scale that is not compatible with public environmental expectations and environmental policies of the 21st century. In this study, an environmentally compatible synthesis route has been established using a microbial strain to enzymatically convert benzoates into cis, cis-muconic acid. Subsequent catalytic hydrogenation of the cis, cis-muconic acid affords adip

The influence of operating variables on the mineralization efficiency and decolorization rate were studied as a function of the molar proportion of vanadium-doped, current density, electrolyte concentration and the initial pH. FE-SEM images showed that the maximum uniformity particles and the best neat arrangement in 0.1 VT electrode. EDS and ESCA images showed that the implanted V ions existed in the lattice of TiO2.
