Реферат: BACKGROUND The development of highly efficient and selective bimetallic catalytic systems for the hydrogenation of unsaturated compounds is an important scientific task. RESULTS A new bimetallic 1%Cu-1%Pt/SiO2 catalyst for the selective hydrogenation of phenylacetylene was developed. The bimetallic catalysts were prepared by a consecutive incipient wetness impregnation method and a redox method with preadsorbed hydrogen. We showed that the catalytic properties of 1%Cu-1%Pt/SiO2 catalysts and selectivity toward styrene depend on the states of metals and interactions between Cu and Pt in bimetallic particles. The strong contact interaction between Pt0, Ptδ– and Cu<2+ in sample prepared by the impregnation method provides a high selectivity of about 82% in styrene formation, while the interaction between PtO and CuO phases provides a 60% selectivity under mild conditions. CONCLUSIONS A new highly effective bimetallic Cu-Pt/SiO2 catalyst was found for the selective hydrogenation of phenylacetylene with the formation of styrene. © 2021 Society of Chemical Industry (SCI).
