Self-Powered and Highly Efficient Production of H2O2 through a Zn–Air Battery with Oxygenated Carbon Electrocatalyst
Source abstract
Abstract
Industrially producing H2O2 consumes lots of energy and generates byproducts. For the first time, we demonstrate the non-energy-consuming, self-powered production of H2O2 based on a Zn–air battery with oxygenated carbon electrocatalyst. The battery with power density of 360 W mgeo–2 at a operating voltage of 0.8 V exhibited high H2O2 production rate of 5.93 mol mgeo–2 h–1. By tuning the ratio of the oxygen-containg groups, the origin of the high activity was investigated. Combining the DFT calculations, we found that C–O–C and −CHO contribute more to the H2O2 production compared to other functional groups.
