Abstract Exploring efficient electrocatalysts with fundamental understanding of the reaction mechanism is imperative in CO 2 electroreduction. However, impact sluggish water dissociation as proton source and surface species are still unclear. Herein, we report a strategy promoting protonation electroreduction by implementing oxygen vacancy engineering on Bi O 3 over which high Faradaic efficiency formate (above 90%) large partial current density (162 mA cm −2 ) achieved. Systematic study reveals that production rate mainly hampered dissociation, while introduction accelerates kinetics strengthening hydroxyl adsorption reduces energetic span Moreover, * involved formation key clearly identified electron spin resonance measurements designed situ Raman spectroscopy combined isotopic labelling. Coupled photovoltaic device, solar to energy conversion reaches 13.3%.

Enhancing Local CO₂ Adsorption by L‐histidine Incorporation for Selective Formate Production Over the Wide Potential Window

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(49)

Опубликована: Окт. 19, 2023

Electrochemical carbon dioxide reduction reaction (CO2 RR) to produce valuable chemicals is a promising pathway alleviate the energy crisis and global warming issues. However, simultaneously achieving high Faradaic efficiency (FE) current densities of CO2 RR in wide potential range remains as huge challenge for practical implements. Herein, we demonstrate that incorporating bismuth-based (BH) catalysts with L-histidine, common amino acid molecule proteins, an effective strategy overcome inherent trade-off between activity selectivity. Benefiting from significantly enhanced adsorption capability promoted electron-rich nature by L-histidine integrity, BH catalyst exhibits excellent FEformate unprecedented windows (>90 % within -0.1--1.8 V >95 -0.2--1.6 versus reversible hydrogen electrode, RHE). Excellent performance can still be achieved under low-concentration feeding (e.g., 20 vol.%). Besides, extremely low onset -0.05 VRHE (close theoretical thermodynamic -0.02 ) was detected situ ultraviolet-visible (UV-Vis) measurements, together stable operation over 50 h preserved ≈95 partial density 326.2 mA cm-2 at -1.0 .
