Abstract

This invention relates to a Ru-Ni bimetallic catalyst for the selective hydrogenation of quinoline-based organic hydrogen storage supports, its preparation method, and its application. The catalyst uses carbon nitride as a support, with Ru and Ni nanoparticles as active components co-supported on the carbon nitride support. The carbon nitride is prepared by mixing carbon tetrachloride, ethylenediamine, and nano-silica, reacting to obtain a carbon nitride polymer, calcining at 750-850°C, desilication treatment, filtering, and drying. The catalyst provided by this invention exhibits excellent catalytic hydrogenation performance in the selective hydrogenation of quinoline-based organic hydrogen storage supports. It eliminates the need for a solvent in the reaction system, making the reaction simple, environmentally friendly, and maximizing the mass hydrogen storage density of the system when using quinoline compounds as organic hydrogen supports. Furthermore, the catalyst demonstrates excellent cycle stability.
