Abstract

Electrochemical activity and stability depend on the composition and morphology of nanocrystals. Mn₃O₄ nanoplates, Mn₂O₃ nanoplates, and porous Mn₂O₃ nanoplates were synthesized by heat treatment of Mn-glycolate nanoplates prepared by the wet-chemical method. In this research, the morphology and composition of the nanoplates could be easily controlled by varying the annealing temperature. The synthesized porous Mn₂O₃ nanoplates exhibited better electrocatalytic activities compared with Mn3O4 and Mn₂O₃ nanoplates, as similar as commercial IrO₂ catalyst.
