ZIOC researchers developed a new mineral-like catalyst based on nickel phyllosilicate for the selective hydrogenation of unsaturated compounds

Nowadays, materials with a phyllosilicate structure are of great interest in heterogeneous catalysis due to their developed specific surface, high dispersion of the active metal, and the presence of a strong contact interaction between the supported transition metal and the support.

Scientists of the Laboratory for the Development and Research of Polyfunctional Catalysts of the ZIOC together with researchers from Lomonosov Moscow State University developed a new catalyst based on nickel phyllosilicate for the selective hydrogenation of a carbon-carbon triple bond in a number of unsaturated compounds. A nickel-containing catalyst with a micro-mesoporous structure was first synthesized inside the pores of a commercially available SiO2 support by thermal urea hydrolysis precipitation. The developed catalyst has a high selectivity (more than 90%) with respect to the C=C double bond in comparison with the supported catalyst based on nickel oxide and the commercial Raney nickel catalyst, as well as stability for seven cycles of reuse without loss of selectivity.

The results of the study were published in the Molecular Catalysis journal.
