Highly Dispersed Metal Carbide on ZIF-Derived Pyridinic-N-Doped Carbon for CO Enrichment and Selective Hydrogenation.

Catalytic conversion of CO into chemicals is a critical issue for energy and environmental research. Among such reactions, converting CO into CO has been regarded as a significant foundation to generate a liquid fuels and chemicals on a large scale. In this work, zeolitic imidazolate framework-derived N-doped carbon-supported metal carbide catalysts (M/ZIF-8-C; M=Ni, Fe, Co and Cu) with highly dispersed metal carbide were prepared for selective CO hydrogenation.
