Description
Summary:[Display omitted] •A novel Mn0.5Cd0.5S/CNTs composite photocatalyst was successfully prepared.•Resulted Mn0.5Cd0.5S/CNTs presents highly heightened visible light response ability.•Resulted Mn0.5Cd0.5S/CNTs exhibits notably separated rate of photoinduced charges.•Resulted Mn0.5Cd0.5S/CNTs presents excellent photocatalysis H2 production performance. In this paper, Mn0.5Cd0.5S/CNTs, a novel composite photocatalytic material, was successfully synthesized by a feasible hydrothermal method. The structure, morphology and photo-property of resulted samples were measured by XRD, SEM, TEM, XPS, PL, UV–vis DRS and photocurrent tests. The visible-light photocatalytic performance was tested via H2 production test. The results indicated that CNTs as electron acceptors could suppress the recombination of holes and charges over Mn0.5Cd0.5S/CNTs photocatalyst, improved H2 production performance of photocatalyst, furthermore, Mn0.5Cd0.5S/CNTs kept excellent steady. Finally, a possible reaction mechanism over Mn0.5Cd0.5S/CNTs was proposed.
