One-pot hydrothermal synthesis: Enhanced MOR and OER performance using low-cost Mn_3O_4 electrocatalyst

摘要

Mn3O4 NPs were synthesized using a simple, rapid, and cost-effective hydrothermal method. High-resolution transmission electron microscopy showed that most of the synthesized NPs were cubic, with some NPs being spherical and hexagonal. The electrochemical results showed that the Mn3O4 cubes were exhibited good oxygen evolution activity (OER) and methanol oxidation activity (MOR) and stability in alkaline media, making them a promising and efficient material in energy applications.
