Facile Fabrication of F-Doped SnO2 Nanomaterials for Improved Photocatalytic Activity

Abstract

Non-metal doping introduces structural defects, which alter the metal oxide band gap, resulting in high photocatalytic performance. Herein, a F doped SnO2 was synthesized via a simple solvothermal method. Through adjusting the solvothermal time, surfactants and F doping ratio, the optimal sample was prepared. In addition, the as-prepared nano-powder was characterized and analyzed by X-Ray-Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Disperse Spectroscopy (EDS) and Fourier Transform Infrared Spectrum (FT-IR). Interestingly, the results of photocatalytic degradation showed that the degradation rate of rhodamine B (Rh B) reached 92.9% in 25 min after a 5-hour solvent heat treatment with polyethylene glycol (PEG) surfactant and F doping ratio of n(F):n(Sn) = 1:15. Through the study of photocatalytic performance, we found that F-doped SnO2 has high photocatalytic activity during a short time and its development potential in the field of photocatalysis, which provides a strong support for our further study of its practical application.

Advances in Sno₂-Based Nanomaterials for Photocatalysis, Supercapacitors, and Antibacterial Activities

“…The SnO2 and SnO2 based materials have been used by different researchers in photocatalysis, SCs, and antibacterial activity as of the present (year 2022). Xiao et al [122] investigated the photocatalytic degradation of RhB using Fdoped SnO2. The RhB degraded at a rate of 92.9% in 25 min following a 5-hour solvent heat treatment with polyethylene glycol (PEG) surfactant and F-doped SnO2.…”
