摘要：The solubility of ammonium tungstate in a special hydrothermal condition is exploited to synthesize uniform microspheres of Ce-Cu-W-O *** to their W-undoped counterparts,they possess more Ce^3+ and oxygen vacancies,thereby promoting oxygen *** formed rich WO3 surface can effectively provide acid sites,which is helpful for adsorption of vinyl chloride and interrupting the C-Cl *** addition,the presence of WO3 induces the formation of finer CuO nanoparticles with respect to the traditional coprecipitation method,thereby resulting in a better *** from both the enhanced acidity and reducibility,the Ce-Cu-W-O microspheres deliver excellent low-temperature vinyl chloride oxidation activity(a reaction rate of 2.01×10^-7 mol/(gcat·s)at 250℃)and high HCl ***,subtle deactivation occurs after the three cycling activity tests,and a stable vinyl chloride conversion as well as mineralization are observed during the 72-h durability test at 300℃,which demonstrates good thermal *** strategy can provide new insights into the design and synthesis of metal oxides for catalytic oxidation of chlorinated volatile organic compounds.
