Platinum–Chromium–Nickel Catalysts of Bicyclohexyl Dehydrogenation, Supported on Oxidized Sibunit Carbon

Bicyclohexyl dehydrogenation using PtCrNi-containing catalysts supported on oxidized Sibunit carbon is studied as a key stage of hydrogen storage and evolution systems using liquid organic hydrogen carriers. It is shown that modifying platinum with nickel and chromium raises the specific activity of the catalyst considerably, relative to the evolution of hydrogen at a low content of the noble metal (0.1 wt % Pt). It is found that using an oxidized Sibunit carbon support to synthesize active supported Pt catalysts for bicyclohexyl dehydrogenation does not produce products of side reactions.
