▎ 摘　　要

NOVELTY - A cadmium sulfide/graphene composite material is prepared by adding cadmium nitrate and thiourea in deionized water, stirring to obtain clarified solution A, adding graphene oxide to solution A by uniform ultrasonic dispersion, heating, evaporating to obtain gel, and continuously heating to discharge large amount of gas. USE - Preparation of cadmium sulfide/graphene composite material for sewage treatment and organic substance enrichment. ADVANTAGE - The preparation is simple, has easy operation and high yield and mass production, and obtains product with excellent photo-catalytic property. DESCRIPTION OF DRAWING(S) - The drawing shows an X-ray diffraction map of prepared cadmium sulfide/graphene composite material. (Drawing includes non-English language text).
