NOVELTY - Preparation of graphene-antimony sulfide nanorods composite visible photocatalyst comprises taking graphene oxide, adding to o-hydroxyl glycol, sonicating to prepare graphene oxide-o-hydroxy diol dispersion; adding antimony trichloride, heating and stirring to dissolve, adding sulfur powder, and stirring to obtain mixing liquid; adding sodium borohydride into mixing liquid, and stirring under reflux at 160-200 degrees C for 5-15 hours; and cooling to room temperature, centrifuging to obtain black precipitate, washing black precipitates with deionized water and anhydrous ethanol, and drying. USE - Method for preparing graphene-antimony sulfide nanorods composite visible photocatalyst (claimed). ADVANTAGE - The method has simple process, high process safety, easy to control reaction parameter and low cost which fits for industrial production. DETAILED DESCRIPTION - Preparation of graphene-antimony sulfide nanorods composite visible photocatalyst comprises taking graphene oxide, adding to o-hydroxyl glycol, sonicating for 1-3 hours to prepare 0.5-2 mg/mL graphene oxide-o-hydroxy diol dispersion; adding antimony trichloride at ratio of 1:300-500, heating and stirring to dissolve, adding 2-4 times sulfur powder, and stirring to obtain mixing liquid; adding 2-4 times sodium borohydride into mixing liquid, and stirring under reflux at 160-200 degrees C for 5-15 hours; and cooling to room temperature, centrifuging to obtain black precipitate, washing black precipitates with deionized water and anhydrous ethanol, and drying.
