Optimization of CdS/TiO2 Nano-Bulk Composite (NBC) Photocatalysts for Hydrogen Production from Na2S/Na2SO3 Aqueous Electrolyte Solution under Visible Light (λ≥420nm) |
초록 |
Nano-bulk composite (NBC) photocatalysts based on bulk CdS were fabricated as precipitation method and sol-gel synthesis. CdS-TiO2 NBC photocatalyst consisted of bulky CdS with a high crystallinity decorated with nanosized TiO2 particles. This configuration of the composite photocatalyst exhibited an unprecedented high rate of hydrogen production under visible light irradiation (λ≥420nm) from water containing sulfide and sulfite as hole scavengers. In this work, we investigated the physicochemical properties of CdS(bulk)/TiO2 composite photocatalysts and optimized their preparation conditions for the high photocatalytic activity of hydrogen production from water containing Na2S and Na2SO3 as a sacrificial reagents under visible light irradiation. |
