One of the most effective ways to cope with the problems of global warming and the energy shortage crisis is to develop renewable and clean energy sources. To achieve a carbon‐neutral energy cycle, advanced carbon sequestration technologies are urgently needed, but because CO 2 is a thermodynamically stable molecule with the highest carbon valence state of +4, this process faces many challenges. In recent years, electrochemical CO 2 reduction has become a promising approach to fix and convert CO 2 into high‐value‐added fuels and chemical feedstock. However, the large‐scale commercial use of electrochemical CO 2 reduction systems is hindered by poor electrocatalyst activity, large overpotential, low energy conversion efficiency, and product selectivity in reducing CO 2 . Therefore, there is an urgent need to rationally design highly efficient, stable, and scalable electrocatalysts to alleviate these problems. This minireview also aims to classify heterogeneous nanostructured electrocatalysts for the CO 2 reduction reaction (CDRR).
