P-n Heterojunction Photocatalyst Mn_0.5Cd_0.5S/CuCo₂S₄ for Highly Efficient Visible Light-Driven H₂ Production.

ABSTRACT: It is highly important to develop efficient and cheap photocatalysts for hydrogen production. Herein, a series of p-n heterojunction Mn_0.5Cd_0.5S/CuCo₂S₄ has been successfully synthesized for the first time by the hydrothermal impregnation method. Mn_0.5Cd_0.5S/CuCo₂S₄ loading with 12 wt % CuCo₂S₄ shows the highest H₂ evolution rate of 15.74 mmol h^-1 g^-1 under visible light (λ ≥ 420 nm) irradiation, which is about 3.15 and 15.28 times higher than that of bare Mn_0.5Cd_0.5S (4.99 mmol h^-1 g^-1) and CuCo₂S₄ (1.03 mmol h^-1 g^-1), respectively. In addition, it shows a relat
