The direct production of formate from CO2 over Bi-based catalysts offers a promising route for producing important chemicals using renewable electricity. Nevertheless, limited by the unstable structure and states under electrochemical conditions, electroreduction to is still facing trade-off between activity stability, especially at high current densities. Herein, we reported metal–carbon interfacial modulation strategy synthesize cross-linked defective carbon-modified Bi nanoparticle (Bi-DC) catalyst with stable spatial unique CO2-philic hydrophobic interface. As result, Bi-DC featured remarkable ability in near neutral electrolyte (1 M KHCO3) was even comparable CO2-to-formate strongly basic systems, along partial density formation rate −378 mA cm–2 7 mmol h–1, respectively. Also, it achieved electrolysis 120 h 0.4 A membrane electrode assembly reactor operated stably an industrial large 5 A. carbon species promoted reconstruction dispersion active component Bi, together confinement effect that facilitated long-term electrolysis.

In the past decade, density functional theory (DFT) calculations have been employed to study mechanism of electrochemical CO2 reduction reactions. However, lack understanding chemisorption states, proton-coupled-electron-transfer (PCET) steps, and dynamic redox reactions electrode surface has limited reliability these simulations. The *OCHO *COOH species are widely recognized as key intermediates for formic acid carbon monoxide production, respectively. comparison between binding energies cannot directly indicate reaction trends. this work, we propose that energy difference on neutral extra-electron substrates, in form [ΔG(*COOHe) – ΔG(*COOH)], can serve a descriptor selectivity. addition, computational hydrogen (CHE) model is revised by applying previously studied charged species. noninteger charge-transfer (NICT) used calculation profile at certain potential, which good prediction potential-limiting step. oxide metal electrodes found play role modulating selectivity improving electron transfer CO2.
