NOVELTY - Preparation of three-dimensional molecularly imprinted photocatalytic composite material involves preparing bismuth oxyiodide nanoparticles using bismuth nitrate, potassium iodide and polyvinylpyrrolidone-K30 as raw materials, dissolving p-nitrophenol and pyrrole in liquid mixture of methanol and distilled water, stirring, prepolymerizing resultant solution on surface of the prepared particles using iron(II) chloride as catalyst, eluting using sodium hydroxide solution, and mixing obtained product and graphene oxide in a mass ratio of 100:5-100:100. USE - Preparation of three-dimensional molecularly imprinted photocatalytic composite material used in degradation of organic pollutants in wastewater treatment. ADVANTAGE - The method enables efficient preparation of three-dimensional molecularly imprinted photocatalytic composite material having excellent selective decomposition capability with respect to organic pollutants in wastewater treatment. DETAILED DESCRIPTION - Preparation of three-dimensional molecularly imprinted photocatalytic composite material involves preparing bismuth oxyiodide nanoparticles using bismuth nitrate, potassium iodide and polyvinylpyrrolidone-K30 as raw materials, dissolving p-nitrophenol and pyrrole in liquid mixture of methanol and distilled water in a volume ratio of 1:1, stirring in dark for 30 minutes, prepolymerizing resultant solution on surface of the prepared particles using iron(II) chloride as catalyst, eluting using sodium hydroxide solution, forming imprinting hole, and mixing obtained product and graphene oxide in a mass ratio of 100:5-100:100.
