摘      要：Soil remediation containing numerous organic contaminants is of great significance to ecological ***,the synergetic effects of Ce-Mn/Al2O3with different active components on catalytic thermal desorption of chlorobenzene in soil were *** optimized Ce-Mn/Al2O3drastically enhance the desorption efficiency of chlorobenzene,and the corresponding conversion reaches 100%within 1 h at a low temperature of 120℃.The superior performance is ascribed to the formation of Ce-Mn solid solution during the calcination process,resulting in a certain lattice change to the generation of abundant oxygen vacancies and acidic *** with the analysis of in-situ diffuse reflectance infrared spectroscopy and gas chromatography-mass spectrometry,the final products of chlorobenzene are decomposed into CO2,H2O,Cl2and *** work sheds light on the rational design of highly-active catalysts for practical applications of sustainable soil remediation.
