Abstract The precise regulation of active sites to steer reaction pathway for photocatalytic CO 2 reduction is critical, but remains challenges. Herein, an inert heteroatom substitution strategy developed activate adjacent dual‐active‐sites boosting diluted . As a proof concept, Co 2+ δ /Ni ζ in layered double hydroxides (LDHs) photocatalyst with high activity interspaced and regulated by Al substitution. corresponding elementary step optimized, where the Ni site shows activation weak absorption *CO, whilst facilitates water oxidation. Most importantly, produced *H on synchronized formation *COOH site, which synergistically lowers energy barrier (*CO *COOH) rate‐determining step. Resulting CoNiAl‐LDHs attains nearly 100% selectivity production rate 784 µmol g −1 h toward CO, representing best performance reported date. This work delivers feasible via proximate dual sites, provides fundamental guidance design photocatalysts reduction.
