Abstract

The CO2 reduction reaction (CO2RR) and oxygen reduction reaction (ORR) show great promise for expanding the use of renewable energy sources and fostering carbon neutrality. Sn-based catalysts show CO2RR activity; however, they have been rarely reported in ORR. Herein, we prepared a nitrogen-carbon structure loaded by Fe-doped Sn nanoparticles (Fe-Sn/NC), which has good ORR and CO2RR activity. The results reveal that the Fe-Sn/NC catalysts deliver a high FECO of 99.0% at a low overpotential of 0.47 V in an H-type cell for over 100 h. Notably, a peak powder density of 1.36 mW cm-2 is achieved in Zn-CO2 battery with the Fe-Sn/NC cathode at discharge current densities varies from 2.0~4.0 mA cm-2, and the FECO remains above 99.0%. Due to efficient oxygen reduction reaction (ORR) performance and Zn-air battery (ZAB) characteristics, ZAB-driven CO2RR has strong catalytic stability. This work proves that Fe-Sn/NC enhances the performance of CO2RR and ORR, and the study of Zn-based batteries provides a new research direction for energy conversion.
