负载型纳米金催化剂在环己烷氧化中的催化性能

 采用沉积-沉淀（DP）的方法制备了负载型催化剂Au/TS-1，采用XRD，FT-IR，SEM，TEM等方法对制备的催化剂进行了表征，并将其用于催化环己烷氧化反应。结果表明，该催化剂在环己烷氧化反应中具有优异的催化活性。当加入0.02g Au的负载量为1%的催化剂Au/TS-1, 在压力1.0MPa、150℃下反应2.5h，环己烷的转化率最高可达到11.20%，环己酮、环己醇和环己基过氧化氢的总选择性达到89.60%, 且催化剂使用4次后活性基本不变。

CATALYTIC PERFORMANCE OF SUPPORTED NANO-GOLD CATALYST IN CYCLOHEXANE OXIDATION

Supported Nano-gold Catalyst was prepared by deposition-precipitation method. The obtained Au/TS-1 was characterized and analyzed by FT-IR, XRD, IR, SEM and TEM，and applied for cyclohexane selective oxidation. It was found that the Au/TS-1 catalyst showed high catalytic performance on cyclohexane selective oxidation. The results showed that this catalyst had 11.20% cyclohexane conversion and 89.20% selectivity at 150℃ for 2.5h under the pressure of 1.0MPa. Moreover the catalytic activity of Au/TS-1 has only a slight lost after reused three times.
