Electrocatalytic reduction of CO 2 into high energy‐density fuels and value‐added chemicals under mild conditions can promote the sustainable cycle carbon decrease current energy environmental problems. Constructing electrocatalyst with activity, selectivity, stability, low cost is really matter to realize industrial application electrocatalytic (ECR). Metal–nitrogen–carbon (M–N–C), especially Ni–N–C, display excellent performance, such as nearly 100% density, outstanding tolerance, etc., which considered possess broad prospects. Based on research status, starting from mechanism ECR existence form Ni active species, latest progress Ni–N–C electrocatalysts in electroreduction systematically summarized. An overview emphatically interpreted regulatory strategies for activity optimization over including N coordination modulation, vacancy defects construction, morphology design, surface modification, heteroatom activation, bimetallic cooperation. Finally, some urgent problems future prospects designing catalysts are discussed. This review aims provide guidance design development practical application.
