摘要
Exploring reversible Zn–CO2 batteries holds great promising potential for future CO2 fixation and energy supply. Herein, the bifunctional PdBi alloy anchoring on carbon substrate (BiPdC) is proposed for simultaneously catalyzing carbon dioxide reduction reaction (CO2RR) and formic acid oxidation (FAO). The synergistic effect between Pd and Bi overcomes the sluggish kinetics of CO2RR and FAO, causing the HCOOH Faraday efficiency (FEHCOOH) of 63.4% and 6.2 mA cm–2 current density for FAO. Benefiting from the CO2–HCOOH interconversion, the homemade reversible Zn–CO2 battery exhibits the optimal 52.6% FEHCOOH and 1.1 V voltage gap within 45 h of cycling.
