One‐Step Approach for Constructing High‐Density Single‐Atom Catalysts toward Overall Water Splitting at Industrial Current Densities

single atoms and remodeled Pt triple-atom sites enhanced the occupancy of Ir-O bonding orbitals and improved the occupation of Pt-H antibonding orbital, respectively, contributing to the formation of the O-O bond and the desorption of hydrogen. This one-step approach was also generalized to fabricate other 20 single-atom catalysts.
