| 摘要: 应用溶剂化金属原子浸渍(SMAI)法和普通浸渍(CI)法制备了金属含量相同的γ-Al2O3负载Ni-Ag双金属催化剂。研究了这些催化剂在甲苯和二丙酮醇加氢以及CO2甲醇化反应中的催化性质，结果表明与组成相同的普通浸渍法催化剂相比，在所有这些反应中SMAI催化剂都显示出较高的催化活性，这是因为SMAI催化剂具有较高的分散度和还原度(零价金属百分比)。 |

| Abstract: The Solvated Metal Atom Impregnation (SMAI) and Conventional Impregnation (CI) methods were used to prepare Ni-Ag/γ-Al2O3 bimetallic catalysts with the same content. The catalytic properties of these catalysts in hydrogenation of toluene and diacetone alcohol as well as CO2 methanation were studied. The results showed that the SMAI catalysts exhibited much greater activities for all the reactions compared with the CI catalysts with the same composition. This is because the SMAI catalysts possess higher despersity and reaction degree (percentage of metal in zerovalent state). |
