A Facile Approach for the Synthesis of Zn₂SnO₄/BiOBr Hybrid Nanocomposites with Improved Visible-Light Photocatalytic Performance.

ABSTRACT: In this study, a novel Zn₂SnO₄/BiOBr hybrid photocatalyst was prepared via a mild hydrothermal synthesis combined with a chemical deposition method. The morphological structure, chemical composition, crystal structure, and optical properties were comprehensively characterized by a series of measurement techniques. Morphological observation showed that fine Zn₂SnO₄ nanoparticles were anchored on the nanoplate surface of a flower-like BiOBr 3D hierarchical structure. The experimental results of UV-vis diffuse reflection spectroscopy revealed that the visible-light absorptive capacity of the Zn₂SnO₄/BiOBr hybrid photocatalyst was promoted, as compared to that of pure Zn₂SnO₄. Evidenced by electro-negativity theoretical calculation, Zn₂SnO₄ and BiOBr possessed matched band edges for accelerati
