| Abstract: | Three-dimensional (3D) manganese oxides consisted of tetragonal phase Mn3O4 and α-MnO2 with different morphology have been directly grown vertically on Ti foil by a simple electrochemical method without any template and used as the catalysts for oxygen evolution reaction (OER). The results show that manganese oxides with different morphology show high activity and good stability for OER and the manganese oxide (MnOx) nanowire arrays obtained at 70 °C show higher activity and better stability than MnOx with cotton wool structure and MnOx nanosheet arrays. |
