摘要: 在室温下制备了Cu-HMS(六方介孔硅酸盐)介孔含Cu杂原子分子筛,利用XRD、IR和ESR对其进行了表征,表明Cu原子已进入硅酸盐骨架。探讨了这种新型杂原子分子筛对苯酚羟化反应的催化作用,发现Cu-HMS与V-HMS,Ti-HMS,TS-1,Cu-ZSM-5和Cu-Y相比,具有较高的催化活性。研究了反应介质及pH值对苯酚羟化反应的影响,并给出了相应的反应机理。

Abstract: Copper containing mesoporous molecular sieve(Cu-HMS)was prepared at room temperature; XRD, IR and ESR spectra studies revealed the incorporation of copper in the framework. Compared with other catalysts V-HMS, Ti-HMS, TS-1, Cu-ZSM-5 and Cu-Y, Cu-HMS showed an excellent catalytic activity for phenol hydroxylation with hydrogen peroxide as oxygen donor. The mechanism of the reaction has been discussed.

Key words: Cu-HMS, mesoporous molecular sieve, phenol hydroxylation, hydrogen peroxide
