Abstract Formic acid (or formate) is suggested to be one of the most economically viable products from electrochemical carbon dioxide reduction. However, its commercial viability hinges on development highly active and selective electrocatalysts.

The electrochemical CO2 reduction reaction (CO2 RR) is of great importance to tackle the rising concentration in atmosphere. RR can be driven by renewable energy sources, producing precious chemicals and fuels, with implementation this process largely relying on development low-cost efficient electrocatalysts. Recently, a range heterogeneous potentially single-atom catalysts (SACs) containing non-precious metals coordinated earth-abundant elements have emerged as promising candidates for RR.

Bismuthene for highly efficient carbon dioxide electroreduction reaction

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Feb. 27, 2020

Abstract Bismuth (Bi) has been known as a highly efficient electrocatalyst for CO 2 reduction reaction. Stable free-standing two-dimensional Bi monolayer (Bismuthene) structures have predicted theoretically, but never realized experimentally. Here, we show the first simple large-scale synthesis of Bismuthene, to our knowledge, and demonstrate its high electrocatalytic efficiency formate (HCOO − ) formation from The catalytic performance is evident by Faradaic (99% at −580 mV vs. Reversible Hydrogen Electrode (RHE)), small onset overpotential (<90 mV) durability (no decay after 75 h annealing 400 °C). Density functional theory calculations structure-sensitivity reaction over Bismuthene thicker nanosheets, suggesting that selective HCOO indeed can proceed easily on (111) facet due unique compressive strain. This work paves way extensive experimental investigation in many different fields.
