NOVELTY - Porous graphene-zeolite-bismuth oxyhalide photocatalytic material comprises 9-50 pts. wt. porous graphene, 50-91 pts. wt. zeolite and 10-100 pts. wt. bismuth oxyhalide. USE - The material is useful in photocatalytic degradation of organic pollutants in water by visible light (claimed). ADVANTAGE - The material can give better support bismuth oxyhalide, increases specific surface area of bismuth oxyhalide, reduces bismuth oxyhalide crystal grain size, and remarkably improves catalyst activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing porous graphene-zeolite-bismuth oxyhalide photocatalytic material comprising (i) adding graphite powder into concentrated sulfuric acid, ice salt bath cooling by adding potassium permanganate, stirring reaction at room temperature, diluting with water, then adding hydrogen peroxide, removing impurities by centrifugation, subjecting the resulting supernatant to ultrasonic and microwave treatment to obtain oxidized graphene solution, then adding sodium hydroxide, sintering at 700-800 degrees C under nitrogen atmosphere to obtain porous graphene, (ii) adding the porous graphene obtained in step (i) into ethanol, ultrasonicating by adding zeolite, then uniformly mixing, heating to 700-800 degrees C and sintering to obtain porous graphite-zeolite composite material, and (iii) adding bismuth oxyhalide( BiOX) into ethanol, then adding porous graphene-zeolite composite material obtained in step (ii), ultrasonic dispersing after freeze-drying to obtain porous graphene-zeolite-bismuth oxyhalide photocatalytic material.
