摘要
A bismuth oxyiodide/zinc oxide composite material and a preparation method therefor and an application thereof in piezoelectric-photocatalytic removal of organic pollutants. The conductive substrate spin-coated with a zinc oxide seed solution is annealed and added to a precursor solution for reaction to obtain a zinc oxide nanorod array (ZnO NRs); the zinc oxide nanorod array is added to a bismuth oxyiodide precursor solution for reaction to obtain the bismuth oxyiodide/zinc oxide composite material (BiOI/ZnO NAs). The composite material is put in an aqueous solution containing bisphenol A, absorption is performed in the dark for half an hour, and then ultrasound and visible light are used together to remove organic pollutants in the water. After piezoelectric-photocatalytic degradation for 90 minutes, bisphenol A is almost completely degraded.
