Abstract: Normal temperature catalytic oxidation technology is an emerging VOCs treatment technology.In order to improve the activity of the catalyst and decrease the temperature needed by catalytic reaction in efficient degradation of VOCs,the catalytic degradation of isopropanol at normal temperature is mainly achieved over Pd-doped Cu-BTC modified MOF catalyst.Experimental results show that Pd-doped Cu-BTC has the best catalytic activity and can completely degrade isopropanol at 35℃ when the molar ratio of Cu and Pd is 12∶1.It is found through optimizing the activation temperature that Cu-Pd-BTC activated at 150℃ has the best catalytic activity,and can achieve a degradation effect of more than 93% after 7 cycles of recycling.In addition,the microstructure of Cu-Pd-BTC catalyst is revealed by SEM,EDS,XRD and other characterization methods,which proves the successful synthesis of Cu-BTC and further clarifies the relationship between the structure and catalytic activity of the catalyst.
