A New Strategy in Heterogeneous Catalysis: The Design of Cortex Catalysts

摘要

The majority of chemical transformations in industry are catalytic processes, more than 75% of which are carried out using heterogeneous catalysts. A large group of heterogeneous catalysts are the impregnation catalysts, prepared by impregnating solidsupports with metal salts followed by calcination and reduction at high temperatures. More recently, solvated metal atoms as well as certain molecular metal complexes and metal clusters have been immobilized on commercial solid metal oxides. Another current approach concerns surface organo-metallic chemistry according to which discrete catalytically active species are anchored on solid supports.
