Popis: | 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. |
