LaMnO3was prepared by citrate sol‐gel,coprecipitation,hard template,and hydrothermal methods,respectively,and its catalytic performance for the combustion of vinyl chloride was investigated.N2adsorption‐desorption,X‐ray diffraction(XRD),Raman spectroscopy(Raman),O2temperature programmed desorption(O2‐TPD),H2temperature programmed surface reaction(H2‐TPR)and X‐ray photoelectron spectroscopy(XPS)were used to characterize the physicochemical properties of the LaMnO3samples.The preparation methods had obvious effects on the distribution of oxygen and manganese species on the catalyst surface.The reaction followed the suprafacial mechanism;the activity corresponded with the high amount of Mn4+and adsorbed oxygen species.LaMnO3prepared by the citrate sol‐gel method had the best performance for vinyl chloride combustion with T90of182°C.The optimal activity was attributed to the improved redox capability of Mn4+/Mn3+.More available adsorbed oxygen and Mn4+species on the surface were mainly responsible for the remarkable enhancement of the catalytic activity. 展开更多

Glucose, nitrate, and urea were respectively used as C, B, and N sources doped TiO2 at low temperature sol gel method, The obtained nano TiO2 was characterized by DRS, FIRT, TG-DTG. The photocatalytic properties and the optical response range of the natase nanocrystalline were analyzed and studied with the hybrid orbital theory. The results show that the band gap of the doped TiO2 was narrow, and the photocatalytic ability could be excited by the visible lighL and the doping of non metallic elements broadens the application range of TiO2, so that it could be excited under the visible light and obtained better use value. 展开更多
