Abstract : A simple solid-state reaction was applied to synthesize Fe-doped perovskite-type PBFNO catalysts, and methylene blue decomposition studies were performed in the form of visible light according to the changes in the Fe doping content (0.4 to 1.9 mol ratio compared with Bi mol) and the amount of catalyst used (0.05 to 0.2 g used).

Defect-engineered MOF-801 for cycloaddition of CO2 with epoxides Heterogeneous catalysts based on defective metal-organic frameworks (MOFs) have attracted wide attention due to their facile formation of defects during the synthesis. Herein, two MOF-801(D) and MOF-801(P) were synthesized by solvothermal method using a modulation approach. Synthesized MOFs were characterized by using PXRD, N2 BET, TGA, NH3, and CO2-TPD, CO2 adsorption isotherm, XPS, FT-IR, and FE-SEM.

Fabrication of hierarchically porous MIL-88-NH2(Fe): Highly efficient catalyst for the chemical fixation of CO2 under ambient pressure A hierarchically micro- and mesoporous MIL-88-NH2 metal organic framework was prepared through an easy template directed methodology. Hierarchically porous MIL-88-NH2 promoted the CO2 fixation reactions with epoxide to yield cyclic carbonates at atmospheric pressure, low reaction temperature and solventless condition.
