Cobalt Single‐Atom Catalysts with High Stability for Selective Dehydrogenation of Formic Acid
Year: 2020
Type: article
Abstract: Metal–organic framework (MOF)‐derived Co‐N‐C catalysts with isolated single cobalt atoms have been synthesized and compared with cobalt nanoparticles for formic acid dehydrogenation. The atomically dispersed Co‐N‐C catalyst achieves superior activity, better acid resistance, and improved long‐term stability compared with nanoparticles synthesized by a similar route. High‐angle annular dark‐field–scanning transmission electron microscopy, X‐ray photoelectron spectroscopy, electron paramagnetic resonance, and X‐ray absorption fine structure characterizations reveal the formation of Co II N x centers as active sites. The optimal low‐cost catalyst is a promising candidate for liquid H 2 generation.
