在近中性条件下,以正硅酸甲酯和Cu(APTES)42+(APTES:(EtO)3Si(CH2)3NH2)为前驱体,P123为模板剂,KCl为添加剂合成了不同孔结构的含铜介孔氧化硅材料.扫描电镜和氮气吸附结果表明,当Cu(APTES)42+/TMOS摩尔比较高时能得到具有多级孔结构的材料.在以H2O2为氧化剂的苯酚羟基化反应中,具有多级孔结构的含铜介孔氧化硅材料表现出比单一介孔材料高的催化性能.
Under near-neutral conditions, P123 was synthesized with methyl orthosilicate and Cu (APTES) 42+ (APTES: (EtO) 3Si (CH2) 3NH2) as precursors and KCl as additive The results of scanning electron microscopy and nitrogen adsorption show that the material with multi-level pore structure can be obtained when the molar ratio of Cu (APTES) 42 + / TMOS is high.In the hydroxylation of phenol with H2O2 as oxidant , A copper-containing mesoporous silica material having a multi-stage pore structure exhibits a higher catalytic performance than a single mesoporous material.
