Abstract

Abstract : A series CuS/Mn0.3 Cd0.7 S photocatalysts with nanorod structures were successfully constructed and exhibited particularly high H2 evolution performance from water splitting under visible light irradiation. Abstract : Nanorods, with high length-to-diameter ratio, enhanced optical absorption capacity and scattering properties, have aroused researchers' interests. Herein, novel and crystalline Mn x Cd1− x S (0 ≤ x ≤ 1) nanorods were prepared via a facile solvothermal method. By employing an in situ ion exchange process, CuS/Mn0.3 Cd0.7 S composites were constructed. The prepared catalysts displayed particularly high H2 evolution performance, with the maximum reaching 106.84 mmol g −1 h −1, and 18.32% (λ = 420 nm) apparent quantum efficiency (AQE). The characterization results confirmed that the Mn0.3 Cd0.7 S nanorods and the heterojunction at the contact interface of CuS and Mn0.3 Cd0.7 S were the origin of such fine H2 production. Furthermore, deactivation of the studied catalysts were explored profoundly.
