Abstract

The invention discloses a preparation method of a graphite phase carbon nitride / molybdenum sulfide composite material. The preparation method comprises the following steps of mixing MoS2 and a nitrogen source uniformly, and adding a grinding agent for grinding for 30-60min until the materials are fully mixed uniformly to obtain a mixture, wherein the ratio of addition amount of MoS2 to the nitrogen source to the grinding agent is 1mmol:(3-7)mmol:(1-3)ml; (2) under the protection of N2, heating the mixture in the step (1) to 500-600 DEG C to roast for 3-5h to obtain a g-C3N4 / MoS2 composite material. Hydrogen cyanamide, dicyandiamide, tripolycyanamide or urea is taken as the nitrogen source. By using the method disclosed by the invention, the graphite phase carbon nitride / molybdenum sulfide composite material can be prepared by using a one-step method, so that the preparation process is simplified; and no chemical reagent is added, so that the production cost is reduced.
