To develop novel strategies for fabricating metal carbon‐based materials with desirable compositions and structures for catalysis is of great importance. Here we propose for the first time the utilization of metal ionic liquid as a precursor for the synthesis of metal carbon‐based materials through a one‐step pyrolysis route. The method produces the metal dispersed cross‐linked carbon framework with a highly mesoporous structure. Such a Ni/C−N catalyst exhibits outstanding electrocatalytic activity for CO 2 reduction reaction, i. e ., an excellent CO faradaic efficiency of approximately 94 % at an potential of −0.75 V (versus the reversible hydrogen electrode). The method proposed in this work is simple, convenient, low‐cost, adjustable and versatile for the synthesis of different kinds of M/C−N materials because the structures and properties of metal ionic liquids can be easily designed and tuned by changing the anions and cations.
