Si-doped Al2O3 nanosheet supported Pd for catalytic combustion of propane: effects of Si doping on morphology, thermal stability, and water resistance

Research Progress of a Composite Metal Oxide Catalyst for VOC Degradation

“…In the process of catalytic oxidation of VOCs, the abundant oxygen vacancy is conducive to the adsorption of oxygen and the generated reactive oxygen promotes the oxidation of organic compounds. Water molecules will cover part of the active site, and VOC molecules compete for the reaction area on the catalyst, which affects the catalytic performance . Yang et al found that under the condition of 60% relative humidity, 5CuO/V O –MnO 2 had the best degradation effect on CH 3 SH.…”

“…Water molecules will cover part of the active site, and VOC molecules compete for the reaction area on the catalyst, which affects the catalytic performance. 109 Yang et al 55 found that under the condition of 60% relative humidity, 5CuO/V O − MnO 2 had the best degradation effect on CH 3 SH. This is because the proper amount of water promotes the formation of active substances and enhances the oxidation of CH 3 SH.…”

Triazine covalent organic framework (COF)/θ-Al2O3 composites for supercapacitor application

“…Alumina is a widely used ceramic material, cheap and easy to obtain, and has the advantages of high temperature resistance, high mechanical strength, and good conductivity. Alumina materials have many applications in gas separation, 32 reaction catalysis, 33 energy storage 34 and other fields. Although the conductivity of alumina is lower than that of some other metal oxides, it has higher stability and a larger specific surface area.…”
