为提高常温下对VOCs高效降解中催化剂的活性、降低催化反应温度，以异丙醇为研究对象，通过Pd掺杂的Cu-BTC改性MOF催化剂实现对异丙醇的常温催化降解。结果表明，当Cu与Pd的摩尔比为12：1时，Pd掺杂改性Cu-BTC具有最佳的催化活性，能够在35℃条件下实现对异丙醇的完全降解。对活化温度的优化研究发现，150℃活化后的Cu-Pd-BTC的活性最佳，催化剂在循环利用7次后仍能达到93%以上的降解效果。此外，通过SEM、EDS、XRD等表征手段揭示了Cu-Pd-BTC催化剂的微观结构，证明了Cu-BTC的成功合成，阐明了催化剂的结构与催化活性的关系。

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.
