| 英文摘要 | Ordered mesoporous co3o4 has been synthesized by nanocasting from three-dimensional cubic kit-6 template the cobalt precursor is introduced into the silica pores by the "bi-solvent" method the structure and textural characteristics are investigated by x-ray diffraction. fourier transform infrared spectroscopy, transmission electron microscopy, nitrogen sorption at 77k by changing the hydrothermal temperature of the kit-6 template, two kinds of co3o4 replicas with different mesostructured symmetries are obtained mesopoious co3o4 oxides prepared from kit-6 aged at low temperature have uncoupled sub-frameworks while mesoporous co3o4 oxides prepared from kit-6 aged at high temperature possess coupled sub-frameworks co oxidation is carried out as a model reaction to evaluate the catalytic activity co3o4 replicas with uncoupled sub-frameworks which possess higher surface area and more open pole system exhibit better performance than co3o4 replicas with coupled sub-frameworks the light-off temperature of co oxidation reaches as low as 68 degrees c with a space velocity of 120.000 ml h(-1) g(cal)(-1) over the uncoupled co3o4 replica calcination temperature of the cobalt precursor only has negligible or slight impact on the catalytic activity (c) 2010 elsevier b v all rights reserved |
