Abstract：

The　development　of　high-efficient　electrocatalysts　with　low　applied　voltage　and　robust　stability　is　of　great　importance　for　electrolysis　of　water.　In　this　work,　a　bifunctional　electrode　has　been　developed　by　growing　palladium-modified　FeCoS2　nanosheet　arrays　on　Ni　foam　(Pd-FeCoS2　NAs/NF),　which　can　serve　as　anode　and　cathode　for　alkaline　water　splitting　with　high　activities　and　ultra-strong　durability.　The　Pd-FeCoS2　NAs/NF　shows　overpotentials　of　130　mV　for　hydrogen　evolution　reaction　(HER)　and　202　mV　for　alkaline　oxygen　evolution　reaction　(OER)　at　10　mA　cm−2.　The　alkaline　electrolyzer　is　built　by　employing　Pd-FeCoS2　NAs/NF　as　cathode　and　anode,　delivering　a　current　density　of　50　mA　cm−2　at　1.59　V.　Moreover,　the　electrolyzer　can　run　stably　for　600　h　with　negligible　decline.　©　2023　Wiley-VCH　GmbH.
