“…The semiconductor/MeHCM system could be employed as a photoelectrode in a photoconverter-storage cell due to the wide range of formal potentials of the MeHCM compounds, which potentially adequately overlap the band edge on the side of the semiconductor [21]. In this context, our previous works [22,23] studied the electrosynthesis and photoelectrochemical characterization of the p-Si(1 0 0)/Prussian blue interface. In this paper, we report the electroformation of copper (II) hexacyanoferrate (II) (CuHCF) deposited on n-Si(1 0 0) via two stages: a copper film deposition using an electroless process and the electrodissolution of the Cu film in the presence of hexacyanoferrate (II) ions.…”

“…Semiconductor can take the energy of photon and converts it into electrochemical energy. [118] In photoelectrochemical cells (PEC), semiconductor is dipped into electrolyte solution and the liquid junction potential barrier can be easily established. [119] This semiconductor electrolyte-interface can be used not only for PEC cell, but also for photoelectrolysis, photocatalysis, and photoelectrochemical power generation.…”

The thesis focuses on the fabrication of visible light active TiO 2-based thin film photocatalyst, via a green method, for self-cleaning and potentially other solar energy harvesting applications. TiO 2 is chosen due to its attractive attributes of being inexpensive, nontoxic, photocatalytically active, chemically stable and broad application especially in degrading organic pollutants. However, TiO 2 can only be activated under UV light due to the wide band gap of TiO 2 (3.2 eV). This limits its widespread applications since ultraviolet is only a small part of solar energy (approximately 4%) and almost non-existent in indoor lighting. Transparent, uniform, crack free and visible light-activated single element doped TiO 2 films (N-doped TiO 2 and Fe-doped TiO 2) were successfully fabricated. The precursors were prepared using a "green" aqueous Peroxo Titanic Acid (PTA) solution approach and coated on the glass substrate using hydrophilicity-assisted method. The optimal photocatalytic activity of the N-doped TiO 2 films was about 9.5 and 13.6 times higher than that of un-doped TiO 2 coated glass and commercial self-cleaning glass, respectively. The optimal photocatalytic activity of the Fe-doped TiO 2 films was about 4 times higher than that of un-doped TiO 2. The improvement of photocatalytic activity was mainly due to enhanced visible light absorption by N or Fe doping which is attributed to bandgap narrowing as observed from absorption redshift. ACKNOWLEDGMENTS Firstly, I would like to thank God for His blessing so that I could finally finish this thesis. I would like to thank my supervisor Associate Professor Timothy Tan for his inexhaustible patience, valuable guidance, advice, support and encouragement throughout my research and for the completion of my study and the thesis. I would also like to thank my co-supervisor Dr. Tuti Mariana Lim for her attention, advice, support and reminder to work on the right track of this research. I am especially thankful to Dr. Xu Qing-chi who had contributed mainly in project idea and data analysis for the works on N-doped TiO 2 , C-N-codoped TiO 2 and Bi 2 WO 6 / TiO 2 heterojunctions. I would also like to thank him for his assistance, fruitful discussions, patience, and always willing to teach, support and help me.
