摘要
Well- crystallised TiO2 particles (P-25, 20 - 30 nm in diameter) were directly incorporated into surfactant-templated mesoporous silica particles ( pore diameter: 2.7 nm), and the composite material with a high TiO2 content ( 60 wt%) showed molecular selective and enhanced photocatalysis for decomposition of 4-nonylphenol.
