Abstract

The invention relates to the technical field of photocatalysts, and particularly relates to a preparing method of a Cu2S / g-C3N4 heterojunction photocatalyst. The method includes one-step calcining todirectly obtain the Cu2S / g-C3N4 composite catalyst. A certain amount of cuprous thiocyanate is mixed with ammonium chloride, the mixture is fully ground and then calcined in a tubular furnace, and a product is washed with distilled water and then dried to obtain the Cu2S / g-C3N4 heterojunction photocatalyst. The photocatalyst is prepared through a one-step calcining manner, and a preparation process is simple. The photocatalyst has good visible light response capability, a heterojunction structure facilitates separation of photo-induced electron and holes, catalytic activity is high, and the photocatalyst has high practical value and a good application prospect in the field of environment protection. Raw materials of the photocatalyst are easily available and low in cost, a reaction condition is mild, and the method is free of environment pollution and prone to industrial production.

Description

technical field [0001] The present invention relates to a kind of photocatalyst, relate in particular to a kind of Cu 2 S / g-C 3 N 4 Preparation method of heterojunction photocatalyst. Background technique [0002] As a green technology for environmental pollution control, photocatalytic technology is playing an increasingly important role in the field of environmental protection. However, most semiconductor photocatalysts currently face bottlenecks such as insufficient visible light response and low quantum efficiency. Graphite carbon nitride (g-C 3 N 4 ) as a completely non-metallic semiconductor has the advantages of stable chemical properties, narrow bandgap, and strong compatibility, which makes it have great development potential in the field of photocatalysis. However, simple g-C 3 N 4 The efficiency of visible light catalytic degradation of pollutants is not high, which is mainly due to the fact that the photogenerated electrons and holes generated on the surfa...
