Abstract

A series of supported cobalt-based nanocatalysts were synthesized by a one-step self-reduction method using cobalt-based organic framework as precursor. The effect of self-reduction of carbonization on the catalytic performance of supported cobalt-based catalysts was studied. This method successfully controlled the hierarchically porous structure of supports and the size of cobalt nanoparticles. The prepared Co-based catalysts had high catalytic activity and product selectivity for selective hydrogenation of 1,3-butadiene. Specially, it was found that the catalyst carbonized at 600℃ contained a hierarchically porous structure with large surface area, and a uniform distribution of cobalt nanoparticles without obvious aggregation. Most importantly, the corresponding sample exhibited a rather low 100% conversion temperature at 60℃ for selective hydrogenation of 1,3-butadiene, but with butenes selectivity as high as 61%. This work provides a new strategy for the preparation of supported non-noble metal catalysts with high-performance for hydrogenation reactions.
