Electrocatalytic reduction of carbon dioxide into value-added chemical fuels is a promising way to achieve neutrality. Bismuth-based materials have been considered as favorable electrocatalysts for converting formic acid. Moreover, size-dependent catalysis offers significant advantages in catalyzed heterogeneous processes. However, the size effects bismuth nanoparticles on acid production not fully explored. Here, we prepared Bi uniformly supported porous TiO2 substrate electrocatalytic by situ segregation element from Bi4Ti3O12. The Bi-TiO2 electrocatalyst with 2.83 nm displays Faradaic efficiency greater than 90% over wide potential range 400 mV. Theoretical calculations also demonstrated subtle electronic structural evolutions induced variations nanoparticles, where display most active p-band and d-band centers guarantee high electroactivity toward CO2RR.

Published: Oct. 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 .
