Cooperative ion-exchange and self-redox process to load catalytic metal nanoparticles into a MOF with Johnson-type cages.
نویسندگان
چکیده
Through a cooperative ion-exchange and self-redox process, a new MOF material with nanosized Johnson-type cages has successfully produced Pd- or Ag-NPs in its pores without any external reducing agents, leading to the formation of M-NP-embedded catalysts for the hydrogenation of styrene.

Catalytic Aerobic Oxidation of Alkenes by Ag@Metal Organic Framework with High Catalytic Activity and Selectivity
By coupling of Fe2O3@SiO2 particles with metal organic Framework (MOF) the magnetic MOF structure was fabricated. Precipitation and hydrothermal methods were applied for synthesis of core and MOF. Silver nanoparticles were deposited on nickel based metal organic framework surface and magnetic Fe2O3@SiO2@MOF@Ag was obtained. Because of strong coupling between silver nanoparticles and metal organ...
متن کاملRegulating the spatial distribution of metal nanoparticles within metal-organic frameworks to enhance catalytic efficiency
Composites incorporating metal nanoparticles (MNPs) within metal-organic frameworks (MOFs) have broad applications in many fields. However, the controlled spatial distribution of the MNPs within MOFs remains a challenge for addressing key issues in catalysis, for example, the efficiency of catalysts due to the limitation of molecular diffusion within MOF channels. Here we report a facile strate...
