In contrast, the solid solution Mn0.2Cd0.8S catalyst has been limited for a long time due to its low charge separation efficiency and its tendency to lead to rapid electrons and holes binding. Therefore, on the basis of in-depth study catalysts of Co3(PO4)2 and Mn0.2Cd0.8S, we successfully synthesized flake-shaped stacked nano-flower shaped Co3(PO4)2 and rod-shaped Mn0.2Cd0.8S. In addition, combined with traditional physical heating and stirring method, Mn0.2Cd0.8S was inserted into the petals of Co3(PO4)2, forming a heterojunction between their contact surfaces to promote photocatalytic hydrogen production. The study found that when the amount of Co3(PO4)2 was 10%, the hydrogen reduction efficiency of the composite catalyst reached was the best, reaching 0.57 mmol (11.4 mmol/h/g) within 5 hours, which was three times that of the single catalyst Mn0.2Cd0.8S. The results show that the formation of heterojunction provides an open channel for rapid charge transfer and reduces the consumption of photo generate carriers. Moreover, the flake-like accumulation of Co3(PO4)2 provided a 3D reaction space for Mn0.2Cd0.8S, and increased the reaction active sites omaf, the composite catalyst. Therefore, more effective photo-generated carriers migrate to the surface of Co3(PO4)2 and then participate in the photocatalytic evolution reaction of hydrogen. This study provides a new idea for improving the photocatalytic hydrogen production performance of Mn0.2Cd0.8S catalyst.
