Abstract：

In　order　to　realize　industrial　production　of　hydrogen　through　water　splitting,　it　is　essential　to　develop　a　cost-efficient　and　scalable　approach　to　synthesize　nonprecious　electrocatalysts　with　sufficiently　high　activity　and　stability　to　replace　commercial　noble-metal-based　electrocatalysts.　Herein　we　synthesize　cobalt　phosphide　nanoparticles　dispersed　within　nitrogen-doped　carbon　nanotube　network　(CP@NCNT)　via　scalable　spray　drying　and　thermal　treatments.　As　a　multifunctional　electrocatalyst,　the　CP@NCNT　hybrid　delivers　outstanding　activity　for　HER　(in　both　acidic　and　alkaline　electrolytes),　OER　and　overall　water　splitting.　Remarkably,　it　shows　an　ultra-low　overpotental　of　94　mV　to　obtain　10　mA　cm−2　in　HER.　It　also　demonstrates　outstanding　activity　in　overall　water　splitting,　requiring　only　1.619　V　to　deliver　10　mA　cm−2　with　more　than　72　h’　long-term　stability.　The　combination　of　notable　performance,　multi-functionality　and　highly　scalable　spray-drying　synthesis　method　enables　this　material　as　a　novel　and　cost-efficient　transition　metal-based　electrocatalysts　for　overall　water　splitting.　©　2020
