Low-cost and efficient Mn/CeO2 catalyst for photocatalytic VOCs degradation via scalable colloidal solution combustion synthesis method
文献摘要：
Colloidal solution combustion synthesis(CSCS)is a simple and easy method for mass-production of crys-talline nanomaterials with tunable pore structure.In this work,mesoporous Mn/CeO2 catalysts were fab-ricated via CSCS method coupled with a dip-coating process and used for photocatalytic oxidation(PCO)of toluene.Under vacuum ultraviolet(VUV)irradiation,a high toluene removal efficiency of about 92％was achieved with a toluene reaction rate of about 118 μmol/g/h in a continuous flow reactor.A pos-sible degradation pathway was proposed based on the analysis of intermediates by Fourier transform infrared photoluminescence spectra(FTIR)and GC-Mass.Hydrogen temperature-programmed reduction(H2-TPR),Brunauer-Emmett-Teller(BET)surface areas,photoluminescence spectra(PL)spectra and X-ray photoelectron spectroscopy(XPS)were carried out to analyze physical and chemical properties of the cat-alysts.Compared with MnxCe1-xO2 catalysts synthesized by one step CSCS method,Mn/CeO2 has a higher photocatalytic activity,which is attributed to the presence of higher contents of Ce3+,Mn2+and Mn3+species.The presence of higher contents of these species plays a key role in the activity enhancement of toluene oxidation and ozone decomposition.This method is facile,efficient and scalable,and it may become a promising industrial application technology for catalyst synthesis in the near future.
