| Abstract: | "Catalytic combustion of chlorinated volatile organic compounds (CVOCs) driven by natural sunlight is the promising CVOCs elimination method, which has not been realized. In this work, we designed a new sunlight-driven catalytic system for CVOCs combustion based on a scalable CuMnCeO(x) gel and a new photothermal conversion device. The CVOCs elimination rate of CuMnCeO(x) gel was reached to 99% at 250 degrees C, 25 times higher than that of CuMnCeO(x) in bulk form. Further, the new photothermal conversion device could heat the CuMnCeO(x) gel to 300 degrees C under one standard solar irradiation and this joint showed a stable one standard sunlight-driven CVOCs combustion at the rate of 6.8 mmol g(-1) h(-1), which was more than 7.8 times higher than the state of the art of photocatalytic CVOCs decomposition. Moreover, the new sunlight-driven thermal catalytic system was able to stable full oxidize the CVOCs in the concentration from 0.1 to 1000 ppm. Therefore, the natural sunlight-driven thermal CVOCs combustion system with high activity and zero secondary pollution shows the potential for large-scale industrial applications" |
