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.

To utilize intermittent renewable energy as well achieve the goals of peak carbon dioxide emissions and neutrality, various electrocatalytic devices have been developed. However, reactions, e.g., hydrogen evolution reaction/oxygen reaction in overall water splitting, polysulfide conversion lithium–sulfur batteries, formation/decomposition lithium peroxide lithium–oxygen nitrate reduction to degrade sewage, suffer from sluggish kinetics caused by multielectron transfer processes. Owing merits accelerated charge transport, optimized adsorption/desorption intermediates, raised conductivity, regulation microenvironment, ease combine with geometric characteristics, built-in electric field (BIEF) is expected overcome above problems. Here, we give a Review about very recent progress BIEF for efficient electrocatalysis. First, construction strategies characterization methods (qualitative quantitative analysis) are summarized. Then, up-to-date overviews engineering electrocatalysis, attention on electron structure optimization microenvironment modulation, analyzed discussed detail. In end, challenges perspectives proposed. This gives deep understanding design electrocatalysts next-generation storage devices.

Abstract Electrochemical carbon dioxide (CO 2 ) reduction reaction RR) is an attractive approach to deal with the emission of CO and produce valuable fuels chemicals in a carbon‐neutral way. Many efforts have been devoted boost activity selectivity high‐value multicarbon products (C 2+ on Cu‐based electrocatalysts. However, RR electrocatalysts suffer from poor catalytic stability mainly due structural degradation loss active species under condition. To date, most reported present stabilities over dozens hours, which limits advance for RR. Herein, porous chlorine‐doped Cu electrocatalyst exhibits high C Faradaic efficiency (FE) 53.8 % at −1.00 V versus reversible hydrogen electrode (V RHE ). Importantly, catalyst exhibited outstanding long‐term electrocatalysis 240 h. Experimental results show that chlorine‐induced stable cationic 0 /Cu + well‐preserved structure abundant sites are critical FE run electrochemical reduction.
