Abstract

The undoped and Zn-doped SnO2 products have been synthesized by a solvothermal method. With the Zn doping concentration changing from 0 to 20 mol%, the SnO2 morphology evolved from aggregated nanoprisms into hierarchical porous spheres. The products were characterized by x-ray diffraction, Raman spectroscopy, field emission scanning electron microscopy, energy-dispersive spectroscopy, transmission electron microscopy, selected area electron diffraction, UV-Vis absorption spectra, and photoluminescence spectra analysis. The results showed that Zn doping concentration significantly influenced on the microstructure, size, morphology, and optical property of the SnO2 products. Furthermore, the influence of the doping effect on the photocatalytic performance of the as-prepared SnO2 products was compared. The results revealed that 20 mol% Zn-doped SnO2 with hierarchical porous spheres exhibited excellent efficiency of photocatalytic activity, which could be attributed to their abundant oxygen vacancies, large specific surface area, and porous structure.
