Abstract

Formic acid (HCOOH) is one of the most promising chemical fuels that can be produced through CO₂ electroreduction. However, most of the catalysts for CO₂ electroreduction to HCOOH in aqueous solution often suffer from low current density and limited production rate. Herein, we provide a bismuth/cerium oxide (Bi/CeO_x ) catalyst, which exhibits not only high current density (149 mA cm^-2 ), but also unprecedented production rate (2600 μmol h^-1 cm^-2 ) with high Faradaic efficiency (FE, 92 %) for HCOOH generation in aqueous media. Furthermore, Bi/CeO_x also shows favorable stability over 34 h. We hope this work could offer an attractive and promising strategy to develop efficient catalysts for CO₂ electroreduction with superior activity and desirable stability.

Keywords: CO2 electroreduction; current density; formic acid; production rate.
