Hydrogen-Treated Semiconductor Metal Oxides For Photoelectrochemical (PEC) Water Splitting

技術優勢: Substantially enhanced photocurrent densitiesPhotocurrents saturated at a very low applied biasNo greenhouse gas emissions

詳細技術說明: UCSC researchers have demonstrated that hydrogen treatment can be used to fundamentally improve the performance of TiO2 materials as photoanodes for PEC water splitting. Hydrogen-treated TiO2 nanomaterials, in particular rutile nanowire and anatase nanotubes, yield substantially increased photocurrent densities and the photocurrents saturate at a very low applied bias. These hydrogen-treated TiO2 nanowires and nanotubes open up new opportunities in various areas, including PEC water splitting, dye-sensitized solar cells, and photocatalysis. By replacing TiO2 with new hydrogen-treated TiO2 materials, the efficiencies of these processes and subsequent devices increase significantly.

*Abstract: Photoelectrochemical (PEC) water splitting for solar hydrogen production has attracted extensive interest in the past few decades. In PEC water splitting, hydrogen is produced from water using sunlight and specialized semiconductors called photoelectrochemical materials. Moreover, Titanium dioxide (TiO₂) has been extensively investigated as a photoanode for PEC water splitting. TiO₂photoanodes provide favorable band-edge positions, strong optical absorption, superior chemical stability and photocorrosion resistance, and are low cost. However, reported photocurrent densities and photoconversion efficiencies of TiO₂photoanodes are substantially lower than projected. UC Santa Cruz researchers have developed a strategy which demonstrates that hydrogen treatment can significantly enhance the photoconversion efficiency of TiO₂materials by improving their donor density and electrical conductivity.
