Single‐Atom Anchored Curved Carbon Surface for Efficient CO2 Electro‐Reduction with Nearly 100% CO Selectivity and Industrially‐Relevant Current Density

, outperforming state-of-the-art PC-based catalysts. This work not only offers a new method for the rational synthesis of single atom catalysts with strained geometry to host rich active sites, but also provides in-depth insights for the origin of catalytic activity of curved structure-enriched PC-based catalysts.
