Compared with that of pure UiO-66(Fe/Zr), MoS2/UiO-66(Fe/Zr) exhibits a higher peroxidase-like activity due to the generation of superoxide free radical (˙O2−).

Tīmeklis2016. gada 10. maijs · Abstract A kind of core–shell catalyst with Fe–Zn–Zr as the core and a zeolite (HZSM-5, Hbeta, and HY) as the shell was synthesized by a simple cladding method. The catalyst has an obvious confinement effect on the synthesis of isoalkanes by CO 2 hydrogenation. TīmeklisAmong these catalysts, Fe 0.6 Zr 0.4 O 2 exhibited excellent catalytic activity in the HMF oxidation. A 60.6% FDCA yield and 99.9% HMF conversion could be obtained after 24 h under 2 MPa O 2 pressure and base-free conditions. The good performance could be attributed to the large amount of acidic and basic sites on the surface of the catalyst ... havilah seguros
