| Abstract: | Low temperature combustion of diesel soot is the focus of study in recent years.CuK2 /Al2O3 and Cu2K/Al2O3 catalysts for oxidation of diesel soot were prepared by an in situ synthesis method.Structures and catalytic activities were examined by low temperature nitrogen adsorption/adsorption experiments,X-ray diffraction,X-ray photo electron spectroscopy,and temperature-programmed oxidation.Results indicated that the pore structures of CuK2 /Al2O3 and Cu2K/Al2O3 were mesopore,with pore sizes in the range of 2... |
