Abstract

Currently, the fabrication of low cost and high efficiency electrocatalysts is a hotspot in the study of water splitting. Herein, plasma spray (PS) was used to induce a microcosmic explosion (me) on Ni mesh to modify the nanoscale Ni for the preparation of me-PS-NM electrodes with excellent hydrogen evolution. We also demonstrated that oxygen evolution could be significantly enhanced after the me-PS-NM electrodes were doped with Fe3+. Both electrodes formed a system exhibiting superior activity and stability for overall water splitting without noble metals.
