Abstract Tuning the lattice strain of catalysts represents a powerful strategy to alter their electronic structures and ultimately regulate catalytic performance. Electrocatalytic CO 2 reduction is promising avenue accomplish carbon‐neutral cycle, however, there still lacks distinct systematic understanding effect in electrochemical conversion. In this work, influence on Bi (012) facets formate production studied. The pre‐executed density functional theory (DFT) calculations reveal that compression promotes wrinkling exposed surface increases total state (DOS) active sites at Fermi level. As gradual intensification contraction, selectivity exhibits volcanic alteration, with an optimal contraction 3%. Experimentally synthesized O 3 /Bi heterogeneous catalyst confirms compression. When reaches −3.04% facets, possesses highest Faraday efficiency (FE) 96.17% −1.2 V RHE industrially scalable current −600 mA cm −2 . Additionally, seawater‐based electrolysis, also excellent remarkable FE 95.43% production.

Abstract Doping is a recognized method for enhancing catalytic performance. The introduction of strains common consequence doping, although it often overlooked. Differentiating the impact doping and strain on performance poses significant challenge. In this study, Cu‐doped Bi catalysts with substantial tensile are synthesized. synergistic effects in bismuth result remarkable CO 2 RR Under optimized conditions, Cu 1/6 ‐Bi demonstrates exceptional formate Faradaic efficiency (>95%) maintains over 90% across wide potential window 900 mV. Furthermore, delivers an industrial‐relevant partial current density −317 mA cm −2 at −1.2 V RHE flow cell, while maintaining its selectivity. Additionally, exhibits long‐term stability, surpassing 120 h −200 . Through experimental theoretical mechanistic investigations, has been determined that facilitates adsorption *CO , thereby reaction kinetics. Moreover, presence dopants further diminishes energy barrier formation *OCHO intermediate. This study not only offers valuable insights development effective through but also establishes correlations between lattice strains, properties catalysts.
