沉积时间对一锅式沉积沉淀法制备的Au/Al2O3催化CO氧化性能的影响
Effect of Deposition Time on Catalytic CO Oxidation Performance of Au/Al2O3 Prepared by One-pot Deposition Precipitation Method
摘要
Abstract
To improve the CO oxidation performance of Au/Al2O3 catalyst at room temperature,a one-pot deposi-tion precipitation method was designed and developed.The effect of deposition time on the catalytic performance of Au catalyst was investigated,and the structure-activity relationship of the catalyst was explored by characterizing its physicochemical properties,the size of nano Au particles,and the strong interaction between the Au and its sup-port.The experimental results show that the catalyst prepared using the one-pot deposition precipitation method ex-hibits excellent catalytic performance,and the Au/Al2O3 catalyst prepared with a deposition time of 16 hours has the highest catalytic activity.The activity improvement may result from the appropriate deposition time promoting the full dispersion of nano Au particles on the surface of the carrier,improving the dispersion of nano Au,enhan-cing the strong interaction between the metal and its support,and having better catalytic oxidation ability for CO.关键词
