Abstract
Abstract Copper (Cu)‐based catalysts exhibit distinctive performance in the electrochemical CO 2 reduction reaction (CO 2 RR) with complex mechanism and sophisticated types of products. The management of key intermediates *CO and *H is a necessary factor for achieving high product selectivity, but lack of efficient and versatile strategies. Herein, we designed Pt modified Cu catalysts to effectively modulate the competitive coverage of those intermediates. The Pt single‐atoms and Pt nanoparticles modified Cu catalysts (denoted as Cu‐Pt 1 and Cu‐Pt NPs ) precisely regulated the protonation and dimerization, with the faradaic efficiency (FE) of C 2+ products up to 70.4 % and the FE of CH 4 reaching 57.7 %,…
