Fenton-like Cerium Metal–Organic Frameworks (Ce-MOFs) for Catalytic Oxidation of Olefins, Alcohol, and Dyes Degradation

The cerium ions and 4,4-u2032,4u2032,4U2032u2032-nitrilotribenzoic acid linker was synthesized by a hydrothermal process in a metal scaffold. Ce-MOF is made up of a Lewis acid moiety, i. e. Both 100% and 53% conversions were observed. E. g. , It was applied for the oxidative degradation of dyes. The formation of radical hydroxyl species in the mechanistic study of oxidation. This research found the possibility of improving the oxidative catalytic efficiency, as well as organic pollution reduction by using advanced oxidation techniques using Ce-MOF. Without significantly affecting the material's catalytic performance, the catalyst is recyclable five times.

Ozone catalytic oxidation of low-concentration formaldehyde over ternary Mn-Ce-Ni oxide catalysts modified with FeO_x

We used the Pechini method to synthesize manganese-nickel ternary oxide catalysts and investigated the efficiency of catalytic deposition of formaldehyde and ozone at room temperature in this study. The catalyst demonstrated outstanding water vapor resistance after FeO_x treatment, demonstrating exceptional water vapor resistance and HCHO decomposition under dry conditions. Overall, the ternary mixed-oxide catalyst developed in this research has a promising role in both HCHO and ozone decomposition in the indoor environment.
