Synthetic Mechanism of UiO‐66‐NH₂/BiVO₄/BiOBr Spherical and Lamellar Dual Z‐scheme Heterojunction and Efficient Photocatalytic Degradation of Tetracycline Under Visible Light

Abstract

In order to solve antibiotic pollution, it is necessary to design photocatalysts with high specific surface area and efficient electron transfer performance. In this study, we report that two‐dimensional (2D) BiVO4/BiOBr flakes were anchored on the smooth surface of UIO‐66‐NH2 using a two‐step solvothermal‐hydrothermal approach, which forms the dual Z‐scheme mechanism and has rich specific surface area (306.5 m2/g), uniform particle size (2.05 nm) and wide absorption spectrum (2.76 eV). It shows 89.56 % tetracycline (TC) degradation efficiency within 180 min under visible light illumination due to the excellent adsorption properties and ample active sites. This work provides an effective strategy for designing a novel ternary photocatalyst to the degradation of refractory organic pollutants.
