Bimetallic nanoalloys in heterogeneous catalysis of industrially important reactions: synergetic effects and structural organization of the active components
Abstract:
The review is concerned with correlations between synergetic effects and structural organization of the surface of bimetallic alloys that are used as active components of catalysts for selective hydrogenation of organic compounds and the oxidation of CO in hydrogen-rich mixtures. Studies on the preparation of novel highly efficient catalysts using modern theoretical approaches, computer-assisted molecular design and original synthetic procedures are considered. It is shown that introduction of a second metal into the monometallic catalyst and subsequent formation of an alloy with the modified structure of the surface and near-surface layers leads to nonadditive enhancement of catalytic activity and/or selectivity.
