Abstract Main‐group element indium (In) is a promising electrocatalyst which triggers CO 2 reduction to formate, while the high overpotential and low Faradaic efficiency (FE) hinder its practical application. Herein, we rationally design new In single‐atom catalyst containing exclusive isolated δ+ –N 4 atomic interface sites for electroreduction formate with efficiency. This exhibits an extremely large turnover frequency (TOF) up 12500 h −1 at −0.95 V versus reversible hydrogen electrode (RHE), FE of 96 % current density 8.87 mA cm −2 potential −0.65 RHE. Our findings present feasible strategy accurate regulation main‐group catalysts scale.
