英文摘要: Copper-containing mesoporous silicas with different mesostructures were synthesized by co-condensation of tetramethoxysilane and Cu(APTES)(4)(2+) (APTES: (EtO)(3)Si(CH(2))(3)NH(2)) with predefined copper species using P123 as template and KCl as additive under near neutral conditions. Scanning electron microscopy and nitrogen adsorption characterization showed that the material with a hierarchical pore structure was obtained at high Cu(APTES)(4)(2+)/TMOS ratio. In phenol hydroxylation using H(2)O(2) as oxidant, the material with the hierarchical porous structure showed a higher catalytic activity than that with only the mesoporous structure.
