摘要

作为使用液态有机氢载体的氢存储和进化系统的一个关键阶段，研究了使用氧化锡布尼碳支撑的含铂铬镍催化剂进行双环己基脱氢的情况。研究表明，用镍和铬对铂进行改性，可以大大提高催化剂的比活度，相对于在贵金属含量较低（0.1 wt % 铂）时的氢气进化。研究发现，使用氧化锡布尼碳载体合成双环己基脱氢的活性载体铂催化剂不会产生副反应产物。

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.
