Sequentially managing the coverage and dimerization of *CO on Cu catalysts is desirable for industrial-current-density CO 2 reduction (CO R) to C 2+ , which required multiscale design surface atom/architecture. However, oriented colossally difficult even no longer valid due unpredictable reconstruction. Here, we leverage synchronous leaching ligand molecules manipulate seeding-growth process during R reconstruction construct arrays with favorable (100) facets. The gradient diffusion in reconstructed array guarantees a higher coverage, can continuously supply reactant match its high-rate consumption high partial current density . Sequentially, lower energy barriers facets contribute selectivity Profiting from this sequential management, delivers an industrial-relevant FE C2+ 86.1% C2H4 60.8% at 700 mA cm −2 Profoundly, atomic-molecular scale delineation evolution reaction intermediates undoubtedly facilitate various electrocatalytic reactions.
