Steering the Reaction Pathway of CO₂ Electroreduction by Tuning the Coordination Number of Copper Catalysts

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(23), P. 15917 - 15925

Published: May 28, 2024

Cu-based catalysts are optimal for the electroreduction of CO2 to generate hydrocarbon products. However, controlling product distribution remains a challenging topic. The theoretical investigations have revealed that coordination number (CN) Cu considerably influences adsorption energy *CO intermediates, thereby affecting reaction pathway. with different CNs were fabricated by reducing CuO precursors via cyclic voltammetry (Cyc-Cu), potentiostatic electrolysis (Pot-Cu), and pulsed (Pul-Cu), respectively. High-CN predominantly C2+ products, while low-CN favors CH4 production. For instance, over high-CN Pot-Cu, is main product, Faradaic efficiency (FE) reaching 82.5% partial current density (j) 514.3 mA cm–2. Conversely, Pul(3)-Cu production CH4, achieving highest FECH4 value 56.7% jCH4 234.4 In situ X-ray absorption spectroscopy Raman studies further confirm adsorptions CN, directing pathway CO2RR.

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(50)

Published: Aug. 13, 2024

Abstract Deeply electrolytic reduction of carbon dioxide (CO 2 ) to high‐value ethylene (C H 4 is very attractive. However, the sluggish kinetics C−C coupling seriously results in low selectivity CO electroreduction C . Herein, we report a copper‐based polyhedron (Cu2) that features uniformly distributed and atomically precise bi‐Cu units, which can stabilize *OCCO dipole facilitate for high selective production. The faradaic efficiency (FE) reaches 51 % with current density 469.4 mA cm −2 , much superior Cu single site catalyst (Cu SAC) (~0 %). Moreover, Cu2 has higher turnover frequency (TOF, ~520 h −1 compared nanoparticles (~9.42 SAC (~0.87 ). In situ characterizations theoretical calculations revealed unique structural configuration could optimize moments adsorbate promote generation
