文摘

A NiSe/NF electrode was conveniently prepared from electrodeposition method. The uniform and dense coverage of NiSe on NF provided plentiful surface catalytic sites. The electrode is bifunctional for both electrocatalytic HER and OER in an alkaline electrolyte. The electrode is extremely efficient for OER. A two-electrode water electrolyser based on this janus electrode showed efficient and stable water splitting performance under low cell voltages.
