Аннотация доклада:
Nowadays increasing attention is paid to intermetallic compounds (IMCs) as highly stable heterogeneous catalysts. The unique combination of ionic and covalent bonding results in the homogeneity of both crystal and electronic structures of IMCs providing exclusive catalytic characteristics. Recently, PdIn system was reported as one of the promising IMCs for hydrogenation of substituted alkynes in gas- and/or liquid-phase. One of specific properties of PdIn IMCs is high oxophilicity of indium which can lead to the instability of IMCs. On the other hand selective oxidation of In component may provide a new technique of tuning catalytic characteristics by controlled oxidative treatment. Therefore the main objective of this research was to explore the effect of mild oxidation on the surface structure and catalytic performance of PdIn/Al2O3 in selective hydrogenation of diphenylacetylene (DPA).
