| 摘要: 硅胶颗粒经过400 ℃高温活化后与四氯化硅在无水四氢呋喃溶剂中反应制得氯化硅胶。氯化硅胶再经乙酰胺修饰, 制备得到表面含羰基和氨基的硅胶修饰体。此组装体具有良好的配位能力, 能够与Fe3+进行配位, 从而得到表面催化活性点均匀分布的负载型催化剂。该催化剂对甲醛催化氧化具有良好的催化性能, 最高催化效率高达91.3%。 | |

| Abstract: After heated at 400 ℃, the activated silica gel reacted with silicon tetrachloride to obtain chlorinated silica gel in anhydrous tetrahydrofuran. And a modified silica gel with carbonyl and amino groups on its surface was obtained by the reaction between chlorinated silica gel and acetamide. The modification has good coordination ability to Fe3+, and a supported catalyst with catalytic active site of Fe3+ evenly distributed was then prepared by coordination between Fe3+ and the surface organic modified silica gel. The synthesized catalyst has good catalytic oxidation performance to formaldehyde, and a maximum conversion of formaldehyde is about 91.3%. | |
| Keywords: activated silica gel organic surface supported catalytic oxidation formaldehyde | |
