| Abstract: | A series of Cu-Mn catalyst samples with Ce additive supported on palygorskite (PG) were prepared by the wet impregnation method.The catalyst structure was characterized by X-ray diffraction,transmission electron microscopy (TEM),and temperature-pro-grammed reduction with H2.The state of various active species and their reducibility were investigated and correlated with catalytic performance of the catalyst.The catalyst activity was examined using toluene as a model volatile organic compound.The effect of di... |
