NOVELTY - Preparing bimetal perovskite-loaded graphene-like carbon nitride photocatalyst, involves dissolving antimony trichloride and silver chloride solid medicines in a beaker filled with hydrochloric acid, and heating to dissolve under continuous stirring, then adding cesium chloride to the hot solution to form precipitate at the bottom of the beaker. The precipitate is collected, washed with ethanol, and finally dried in an oven, after the oven is cooled to room temperature, taken out to get Cs2AgSbCl6 (cesium silver antimony chloride) powder. The weighed melamine is added to the prepared alumina crucible, closed the lid, and placed in a muffle furnace for calcination under static air, and finally cooled to room temperature naturally, and collected graphitic carbon nitride (g-C3N4) samples. The Cs2AgSbCl6 bimetallic perovskite and g-C3N4 are added to the solution, then performed direct centrifugation and dried to obtain target photocatalyst. USE - Method for preparing bimetal perovskite-loaded graphene-like carbon nitride photocatalyst. ADVANTAGE - The preparation method has mild conditions, simple to operate, and is conducive to large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a bimetallic perovskite supported graphene-like carbon nitride photocatalyst prepared by method.
