One-pot synthesis of S-scheme MoS/g-CN heterojunction as effective visible light photocatalyst.

Despite pioneering as the holy grail in photocatalysts, abundant reports have demonstrated that g-CN performs poor photocatalytic activity due to its high recombination rate of photo-induced charge carriers. Many efforts have been conducted to overcome this limitation in which the semiconductor-semiconductor coupling strategies toward heterojunction formation were considered as the easiest but the most effective method. Herein, a one-pot solid-state reaction of thiourea and sodium molybdate as precursors at different temperatures under N gas was applied for preparing composites of MoS/g-CN.
