摘要：

The　development　of　efficient　and　durable　non-noble　metal　catalysts　remains　a　challenge　in　electrocatalytic　water　splitting　applications.　To　address　this,　a　bifunctional　catalyst　involving　hierarchical　NiCo2O4@Ni2P　nanorods　grown　on　nickel　nanorod　arrays　(NiCo2O4@Ni2P/NAs)　was　designed　and　fabricated　in　this　study　for　overall　water　splitting　that　provided　high　activity　and　acceptable　stability.　And　if　used　as　the　cathode　and　anode　in　alkaline　media,　the　NiCo2O4@Ni2P/NAs　only　required　1.58　V　to　achieve　a　current　density　of　10　mA　cm(-2),　which　is　superior　to　most　reported　catalysts　and　can　be　attributed　to　a　unique　core-shell　structure　and　coexisting　crystalline/amorphous　Ni2P　phases.　(c)　2020　Elsevier　Ltd.　All　rights　reserved.
