High-Efficiency Oxygen Reduction to Hydrogen Peroxide Catalyzed by Oxidized Mo2TiC2 MXene

Catalysts, Journal Year: 2022, Volume and Issue: 12(8), P. 850 - 850

Published: Aug. 2, 2022

The two-electron oxygen reduction reaction (2e−ORR) pathway electrochemical synthesis to H2O2 has the advantages of low investment and environmental protection is considered be a promising green method. Herein, oxidized Mo2TiC2 MXene (O-Mo2TiC2) was successfully synthesized by facile hydrothermal method as an electrocatalyst in electrocatalytic production. O-Mo2TiC2 achieved 90% selectivity 0.72 V vs. RHE onset potential. Moreover, showed high charge transfer ability long-term stable working 40 h. This significantly enhanced production capacity assigned oxidation treatment generate more oxygen-containing groups O-Mo2TiC2. work provides catalyst candidate for H2O2.
