| Abstract: | Pure silica MCM-41 with surface grafted Cu 2+ ions(donated as CuMCM-41) was synthesized via a novel co-assemble route; XRD, ESR and ion-exchange studies revealed that the copper was located on the surface of the pure silica MCM-41 and coordinated with bridged oxygen in the framework. In addition, we also studied its catalysis behavior for hydroxylation of phenol and naphthol with hydrogen peroxide as the oxygen donor. The experimental results show that Cu-MCM-41 possesses an excellent catalytic activity compared with other catalysts Cu-AlMCM-41 and CuO-MCM-41. |
