摘要

硅酸钛-1 （TS-1）在环己酮氨肟化反应中的催化活性受TS-1中内部Si-OH基团与H2O2、NH3和NH2OH之间的氢键相互作用导致的晶内扩散限制所控制，而这些Si-OH基团可以通过紫外辅助热后处理有效退火，从而增强活性。

Insights into the intracrystalline diffusion limitations of TS-1 in catalytic cyclohexanone ammoximation: effects of the Si–OH groups inside the zeotype micropores†

The catalytic activity of titanium silicalite-1 (TS-1) in cyclohexanone ammoximation is controlled by the intracrystalline diffusion limitations due to the hydrogen-bonding interactions between the internal Si–OH groups in TS-1 and H₂O₂, NH₃, and NH₂OH, while these Si–OH groups can be effectively annealed by an ultraviolet-assisted heat post-treatment, resulting in enhanced activity.
