Ligand Steric Hindrance-Engineered Spatially Asymmetric Single-Atom Catalysts: A New Platform for Electrochemical Oxygen Reduction.
Single-atom catalysts (SACs) have demonstrated tremendous potential in heterogeneous electrocatalysis due to their high atom utilization and well-defined active sites. However, conventional SACs typically exhibit a symmetric electron density distribution, which leads to poor adsorption/desorption and activation of reac...
