Abstract

A CdS/TiO₂ nano-bulk composite photocatalyst consisting of bulky CdS with a high crystallinity decorated with nanosized TiO₂ particles was fabricated by precipitation method and sol-gel synthesis. This configuration of the composite photocatalyst exhibited a very high rate of hydrogen production under visible light irradiation (λ ≥ 420 nm) 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.
