Abstract (en)

[origin: WO2022200411A1] The present invention relates to a new cobalt (Co) catalyst for selective hydrogenations of alkynes to alkenes. The catalyst is prepared by impregnating fumed silica with a cobalt complex comprising, for instance, melamine, drying the impregnated material and pyrolysing it to obtain cobalt nanoparticles and nitrogen-doped carbon supported on silica.
