A preparation method of a photocatalytic material BiOBr/ZnSn(OH) 6 @carbon fiber cloth, which relates to a preparation method of the photocatalytic material. The invention aims to solve the technical problem that the existing photocatalytic material is difficult to recover. In this method, the carbon fiber cloth is put into a mixed solution of water, ethanol and acetone for ultrasonic treatment. The carbon fiber cloth was soaked in aqua regia for 24h, then washed and dried. After the SnCl 4 ยท5H 2 O and ZnCl 2 are made into a solution, the pH value is adjusted; then they are mixed in equal volumes, put into a carbon fiber cloth, left for 6 hours, taken out, washed and dried to obtain ZnSn(OH) 6 @carbon fiber cloth ; Dissolve Bi(NO 3 ) 3 5H 2 O, stir and mix with bromine-containing salt solution; ZnSn(OH) 6 @carbon fiber cloth is put into the mixed solution in the hydrothermal reactor to react, and after washing and drying, BiOBr/ZnSn(OH) 6 @carbon fiber cloth. It is used in the field of photocatalysis. |
