Abstract
Bi2O3 is a photocatalyst with excellent performance; however, its applications are limited due to its wide bandgap. In this paper, by adding BiOI and the metal–organic framework UiO-66, a Bi2O3@BiOI@UiO-66 composite material is obtained with high adsorption capacity, in which the bandgap of Bi2O3 is reduced, the recombination of photogenerated electrons and holes is prevented, the photocatalytic efficiency and stability are improved. In visible light degradation experiments, Bi2O3@BiOI@UiO-66 has obvious degradation effects on Rhodamine B and tetracycline, which are 22.2 and 1.04 times that of pure Bi2O3, respectively. Bi2O3@BiOI@UiO-66 demonstrats its potential as photocatalytic degradation material.
