Abstract
- In this paper, we present our work on electrochemical reduction of CO 2 under ambient conditions using a high-surface-area bismuth (HSA-Bi) catalyst, which is fabricated by electrochemical reduction of BiOCl nanosheets. This HSA-Bi catalyst exhibits surprising selectivity towards reduction of CO 2 to formate with a high Faradic efficiency (~ 92%). In addition, the activity of this catalyst remains stable during long-time electrolysis and maximum current density of ~ 3.7 mA mg - 1 could be obtained. The high activity is attributed to the special nanostructure of catalyst, as indicated by lower overpotential of CO 2 reduction on HSA-Bi than that on commercial Bi powder. The HSA-Bi catalyst is believed to be a promising catalyst for further application. [ABSTRACT FROM AUTHOR]
