Promotion Effect of Lantanum ions on Co/SiO2 Catalysts Prepared via Solvated Metal Atom Impregnation Method 张守民1,吴世华1,黄维平1,石娟1,李保庆1 (1.Department of Chemistry, NanKai University, Tianjin 300071, China) Abstract:In order to assess the promotional effects of La3+ on CO hydrogenation of Co/SiO2 catalyst, solvated metal atom impregnation (SMAI) method was used to prepare unpromoted 10% (mass......
Preparation of Expanded Graphite-based Composites by One Step Impregnation刘成宝,陈志刚Department of Chemistry and Bioengineering,Suzhou University of Science and Technology摘 要:impregnation ratio and the activation temperature were,the easier the porosity development would be.And the BET surface area and the total pore volume were as high as 1978 m2/g and 0.9917 cm3/g......
by impregnation method and characterized by N2 adsorption-desorption and XPS. The catalytic activity of Au/AC for decomposition of ozone and toluene was evaluated. The results show that, under the condition... and after the reaction. Key words: gold catalyst; catalysis; ozone; impregnation 自20世纪80年代后期,HARUTA等[1]发现负载在过渡金属氧化物上的纳米金催化剂对低温CO氧化具有较高的催化活性后,人们掀起了对纳米金催化剂的研究热潮.近年来,载金催化剂在低温CO氧化[2?5],烯,醇类有机物环氧化[6?7],甲烷催......
