The cobalt phosphate water oxidation catalyst (Co–Pi WOC) stabilized, CdS sensitized TiO 2 nanowire arrays for nonsacrificial solar splitting are reported. In this /CdS/Co–Pi photoanode, the Co–Pi WOC acts as hole transfer relay to accelerate surface reaction, serves light absorber wider spectra harvesting, and matrix provides direct pathway electron transport. This triple hybrid photoanode exhibits much enhanced photocurrent density negatively shifts in onset potential, resulting 1.5 3.4...
Cobalt phosphate (Co-Pi) is photo-electrodeposited on TiO2 nanowire arrays in Co(2+) containing buffer. The resulting composite photoanode shows a generally enhanced photocurrent near the flat band potential region, and represents 2.3 times improved photoconversion efficiency compared to that of pristine neutral electrolyte. A negative effect generation also observed when loading with relatively thick Co-Pi layer, which demonstrated be due poor photohole transfer kinetics layer. Moreover, we...

Since the discovery of hydrogen evolution through photoelectrochemical (PEC) splitting water from n-type TiO2 electrodes, technology short-bandgap semiconductors (such as ZnSe, CdS and CdSe) combined with one-dimensional (1D) metal-oxide nanowire (NW) arrays (e.g., ZnO) to enhance their visible-light harvest efficiency has been widely studied. In this study, ZnSe/CdS/CdSe triple-sensitized ZnO NW were successfully fabricated on FTO substrates via a facile hydrothermal anion exchange...
Core/shell heterostructured TiO2/CdSxSe1-x nanowire arrays (NWAs) were prepared via physical vapor deposition of CdSxSe1-x layer onto the hydrothermal pre-grown TiO2 NWAs with FTO as conductive substrate. By change sulfur content (x) in nano-composites, it was observed that light absorption edge can be gradually tuned within a broad wavelength from 540 to 710 nm. When used photoanodes for hydrogen generation, as-prepared show much higher photoelectroncatalytic activity than pristine NWAs....
