AbstractThe MoS2/g-C3N4 heterojunction photocatalyts were successfully synthesized by vacuum freeze drying method and mechanical mixing method in this paper. The pore size and specific surface area of the MoS2/g-C3N4-3% (MC-3%) heterojunction photocatalyst prepared by the vacuum freeze drying method are much higher than those prepared by mechanical mixing method. The photocatalytic hydrogen production rate of MC-3% reaches 30.9 mu mol h(-1), which is approximately 2.6 times that of pure g-C3N4, 7.3 times that of pure MoS2 and 2.4 times that of MC-3% synthesized by mechanical mixing method. And also, the photocatalytic rhodamine B degradation performance of MC-3% is better than that of pure g-C3N4 and pure MoS2. The significant promotion of the photocatalytic performance of MC-3% synthesized by vacuum freeze drying method are due to the larger specific surface areas and the formation of heterojunctions between MoS2 and g-C3N4, which provides more active sites for the photocatalytic reactions and increases the separation efficiency of the photogenerated electrons and holes, thus enhances the photocatalytic performance of g-C3N4. The vacuum freeze drying method is very simple, and the prepared photocatalyst by this method has good performance, which can be widely used in the preparation of composite materials and porous materials.
