The fine regulation of catalysts by the atomic-level removal of inactive atoms can promote the active site exposure for performance enhancement, whereas suffering from the difficulty in controllably removing atoms using current micro/nano-scale material fabrication technologies. Here, we developed a surface atom knockout method to promote the active site exposure in an alloy catalyst. Taking Cu3 Pd alloy as an example, it refers to assemble a battery using Cu3 Pd and Zn as cathode and anode, the charge process of which proceeds at about 1...
