High-curvature single-atom catalysts for electrocatalysis: A review

The catalytic performance of a high-curvature single-atom catalyst is highly dependent on its geometry and the type of metal atoms it carries. This review uses a combination of extensive literature research and theoretical analysis to comprehensively analyze several key aspects of high-curvature single-atom catalysts, including dimension, energy, reaction mechanism, radius of curvature, reaction selectivity, size, different metal atoms, and different types of reactions. In this paper, the unique advantages of high-curvature single-atom catalysts are successfully summarized and refined. On the one hand, it has been found that the surface of this catalyst is highly curved, which promotes the adsorption and reaction of atoms. On the other hand, this paper states that choosing the right radius of curvature is essential to optimize the catalytic process. The comprehensive literature analysis in recent years may provide important reference and enlightenment for researchers, promote the further development of the field of catalysis, and develop more advanced high-curvature single-atom catalytic materials.
