Liu, Mengdi. "Ta₃N₅/Polymeric g-C₃N₄ as Hybrid Photoanode for Solar Water Splitting:." Thesis, Boston College, 2018. http://hdl.handle.net/2345/bc-ir:108366.
Water splitting has been recognized as a promising solution to challenges associated with the intermittent nature of solar energy for over four decades. A great deal of research has been done to develop high efficient and cost-effective catalysts for this process. Among which tantalum nitride (Ta₃N₅) has been considered as a promising candidate to serve as a good catalyst for solar water splitting based on its suitable band structure, chemical stability and high theoretical efficiency. However, this semiconductor is suffered from its special self-oxidation problem under photoelectrochemical water splitting conditions. Several key unique properties of graphitic carbon nitride (g-C₃N₄) render it an ideal choice for the protection of Ta₃N₅. In this work, Ta₃N₅/g-C₃N₄ hybrid photoanode was successfully synthesized. After addition of co-catalyst, the solar water splitting performance of this hybrid photoanode was enhanced. And this protection method could also act as a potential general protection strategy for other unstable semiconductors

In this work, different nanostructured catalytic systems have been synthesized by an organometallic approach to produce nanoparticles (NPs) of small size and narrow size distribution, and their catalytic activity in the water oxidation reaction has been evaluated. First Fe NPs stabilized by oleic acid were synthesized that displayed an average size of ca. 10 nm ± 1.1 nm. A gamma-Fe_2O_3 oxide layer ca. 2.6 nm thick has been formed at their surface to obtain Fe@FeOx core-shell structure of ca. 11.5 ± 2.3 nm in diameter. Despite their hydrophobicity, these nanoparticles showed good electrocatalytic activity in alkaline conditions. As the gamma-Fe_2O_3 oxide shell is well adapted to the grafting of phosphonic groups, these Fe@FeOx NPs were grafted with different aminophosphonic acids in order to transfer them into water. Preliminary assessment of their catalytic activity showed improved activity for the NPs functionalized by 3-aminopropylphosphonic acid which opens promising prospects. Subsequently, a Ru-phenanthroline light-harvester with a pendant phosphonate group was synthesized and grafted onto the Fe@FeOx core/shell NPs to afford a novel hybrid photoanode for solar-driven water splitting. Mono- and biphasic processes were investigated to graft the Ru-complex at the surface of the NPs. The monophasic process was found to be more efficient as it provided a higher grafting density at the surface of the NPs (respectively 56 and 9 Ru per nanoparticles for the mono and biphasic processes). Photoelectrochemical measurements showed that the hybrid nanocatalyst comprising the highest Ru content was ca. 9-fold more catalytically active than a simple mixture between a ruthenium polypyridyl photosensitizer bearing no grafting group and the Fe@FeOx nanoparticles, and 40-fold more active than the pristine Fe@FeOx NPs. The performance enhancement could be attributed to a more efficient electron transfer between the ruthenium polypyridyl photosensitizer and the Fe@FeOx water oxidation catalyst thanks to the covalent bonding between these two components. The covalent grafting was found to improve not only the photocatalytic activity but also the stability of the system. Finally, amorphous NiFe NPs (diameter ca. 4 nm) with two different ratios between Ni and Fe (Ni_0.5Fe_0.5 NPs and Ni_0.68Fe_0.32 NPs) were synthesized, oxidized in air and grafted with 3-aminopropylphosphonic acid in order to obtain hydrophilic systems. The electrocatalytic activity of these water-soluble NPs was studied in alkaline solution, in comparison with that of crude NiOx NPs, FeOx NPs, and Ni_0.1Fe_0.9Ox NPs. The water soluble NPs containing 32 % of Fe (Ni_0.68Fe_0.32Ox) showed the highest activity and a good durability in alkaline solution. These characteristics make these amorphous NPs potentially applicable in photoelectrochemical cells for water splitting

In this study, hydrothermal method was employed to grow 1-D titanate nanorods, which is annealed at 700oC for 2 hours to transfer 1-D titanate to anatase titanium dioxide (TiO2) nanorods. Difference TiO2 photoanodes were make by mixing TiO2 nanorods and P25 particles and different TiCl4(aq) treated time. In order to find out the optimum mixture condition of TiO2 photoanode, different kinds of TiO2 photoanodes were sensitized with N3 dye. The absorbed amount of N3 dye was analyzed by UV-visible absorption spectroscopy. Based on the optimum condition of TiO2 photoanode, quantum dots sensitized photoanode was studied by using home-made CdSeS quantum dots (QDs). In this study, two different kinds of linker, 3-mercaptoproponic acid (MPA) and 11-mercaptoundecanoic acid (MUA), were used to anchor CdSeS QDs on the surface of TiO2 photoanode. The properties of CdSeS QDs sensitized photoanode were characterized by absorption spectroscopy, photoluminescence and lifetime analysis, the band gap structure of CdSeS and MPA or MUA were decided by cyclic voltammetry (CV), and the cell performances were characterized by incident-photocurrent efficiency (IPCE) and current-voltage (I-V) measurement.

In this study, we propose the hybrid nanostructure photoanode for dye-sensitized solar cells, which is made by sol-gel method. It is coated by spin coating on transparent conductive glass (TCO) substrates. The ZnO seeds layer is formed on TCO glass and the ZnO nanorods array is growth on ZnO seeds layer by hydrothermal method.at the temperatures of 80˚C for an hour. The TiO2 nano particles are above on ZnO nanorods array by spin coating. Finally, the solar cell is characteristic by I-V curve measurement and other thin film measurements, such as scanning electron microscopy, X-ray diffractometer, ultraviolet-visible spectroscopy, four point probe measurement. We also demonstrated the effect on the different thermal treatment on ITO and FTO glass, and optimal the recipe of the electrolytes and dye solutions to improve the solar cell energy converting efficiency. As the experimental results shown, in the optimal experiment, it suggest that when the acetonitrile is the major solvent in dye solutions and electrolytes, the cell’s dye adsorption and electron transport efficiency are improved, the solar cell energy converting efficiency is approach 3.95% (TiO2 photoanode) and 0.95%(hybrid nanostructure photoanode).

In this study, one-dimensioanl vertical aligned single crystalline rutile phase titanium dioxide (TiO2) nanorods were grown on transparent conductive fluorine-doped tin-oxide (FTO) glass substrate by hydrothermal method. The diameters, lengths and densities of the nanorods could be controlled by changing the experiment conditions. We also found that vertical aligned TiO2 nanorods could be grown on glass substrates by adding seed layer. Comparing with conventional TiO2 nanoparticles photoanode, one-dimensional vertical aligned single crystalline TiO2 nanorods have directly electrical pathways for photogenerated electrons and enhance the electron transport behavior. However, the dye loading amount decreases due to the effect of surface-to-volume ratio. In order to maintain the dye loading amount, we decorate TiO2 nanoparticles between the gaps of nanorods by using titanium tetrachloride (TiCl4) solution. The efficiency the nanorods/nanoparticles hybrid photoanode around 3~4 μm thickness approaches 3.6%. The photogenerated electron transit time and recombination lifetime are also studied by intensity modulated photocurrent spectroscopy (IMPS) and intensity modulated photovoltage spectroscopy (IMVS).
