NOVELTY - A nano-sheet reduced graphene oxide-flower-shaped multi-layer structure bismuth molybdate heterojunction visible photocatalyst is prepared by adding graphene oxide into water, ultrasonically dispersing to obtain suspension A, dissolving bismuth nitrate and sodium molybdate in dilute nitric acid to obtain solution B, gradually adding solution B into suspension A, stirring for 15-30 minutes, adding hexadecyl trimethyl ammonium bromide, stirring for 60-80 minutes to obtain suspension C, hydrothermally reacting to obtain hydrothermal reaction product, cooling to room temperature, washing and drying. USE - The method is used for preparing nano-sheet reduced graphene oxide-flower-shaped multi-layer structure bismuth molybdate heterojunction visible photocatalyst in degrading 2-naphthol (claimed). ADVANTAGE - The method uses simple and effective one-step hydrothermal method.
