Mesoporous Assembled Mn3O4 Nanoparticle Networks as Efficient Catalysts for Selective Oxidation of Alkenes and Aryl Alkanes

摘要: The design of nanoscale materials has been considered important for enhancing their surface properties catalysis. Metal oxide nanoparticles have a large number exposed active sites, but they suffer from low reactivity and poor stability resulting excessive aggregation into less microscopic structures. Herein, the synthesis mesoporous Mn3 O4 nanoparticle assemblies by polymer-assisted self-assembly is presented catalytic activity demonstrated in oxidation various saturated unsaturated hydrocarbons, including aromatic alkenes aryl alkanes, presence tert-butyl hydroperoxide as mild oxidant. It also shown through comparative studies that high these arise unique three-dimensional open-pore structure, internal area (90 m2  g-1 ) uniform mesopores (≈6.6 nm size).
