Abstract
A CdS/TiO(2) composite photocatalyst consisting of one-dimensional CdS nanowire (NW) with a high crystallinity decorated with nanosized TiO(2) particles (NP) was fabricated by solvothermal method and sol-gel synthesis. The new configuration photocatalyst exhibited higher rate of hydrogen production than that of single CdS NW under visible light irradiation (lambda >= 420 nm) from water containing sulfide and sulfite ions as hole scavengers. Physicochemical properties of CdS NW/TiO(2) NP composite photocatalysts were investigated together with the effect of the mole ratio of TiO(2) and CdS for photocatalytic hydrogen production from water under visible light irradiation.
