Popis: Surface exposed catalytic active species are thought to be responsible for overall catalytic activity and selectivity. In this paper, controllable contents of iron oxides were in situ introduced into the inner surface of anionic surfactant-templated mesoporous silica (AMS) by the metal-modified anionic surfactant templating route, in which anionic micelles decorated with different amounts of Fe2+ were direct utilized to assemble with organosilicate. The characterization results demonstrated that, after thermal treatments, Fe2O3 species were in situ formed and highly-dispersed in the channels of AMS, and the pore size was accordingly tailored to the microporous level (
