[交流] Hydrogen-Treated TiO2 Nanowire Arrays for Photoelectrochemical

We report the first demonstration of hydrogen treatment as a simple and effective strategy to fundamentally improve the
performance of TiO2 nanowires for photoelectrochemical (PEC) water splitting. Hydrogen-treated rutile TiO2 (H:TiO2)
nanowires were prepared by annealing the pristine TiO2 nanowires in hydrogen atmosphere at various temperatures in a range
of 200550 C. In comparison to pristine TiO2 nanowires, H:TiO2 samples show substantially enhanced photocurrent in the entire
potential window. More importantly, H:TiO2 samples have exceptionally low photocurrent saturation potentials of 0.6 V vs Ag/
AgCl (0.4 V vs RHE), indicating very efficient charge separation and transportation.
