The as\u2010fabricated CP@Ni\u2010P electrode exhibits excellent electrocatalytic performance toward hydrogen evolution in both acidic and alkaline solutions, with only small overpotentials of 162 and 250 mV, respectively, attaining a cathodic current density of 100 mA cm<jats:sup>\u22122<\/jats:sup>. Furthermore, the CP@Ni\u2010P electrode also exhibits superior catalytic performance toward oxygen evolution reaction (OER). An exceptionally high OER current of 50.4 mA cm<jats:sup>\u22122<\/jats:sup> is achieved at an overpotential of 0.3 V in 1.0 <jats:sc>m<\/jats:sc> KOH. The electrode can sustain 10 mA cm<jats:sup>\u22122<\/jats:sup> for 180 h with only negligible degradation, showing outstanding durability. Detailed microstructural and compositional studies reveal that upon OER in alkaline solution the surface Ni\u2010P is transformed to NiO covered with a thin Ni(OH)<jats:italic><jats:sub>x<\/jats:sub><\/jats:italic> layer, forming a Ni\u2010P\/NiO\/Ni(OH)<jats:italic><jats:sub>x<\/jats:sub><\/jats:italic> heterojunction, which presumably enhances the electrocatalytic performance for OER. Given the well\u2010defined bifunctionality, a full alkaline electrolyzer is constructed using two identical CP@Ni\u2010P electrodes as cathode and anode, respectively, which can realize overall water splitting with efficiency as high as 91.0% at 10 mA cm<jats:sup>\u22122<\/jats:sup> for 100 h.<\/jats:p>","DOI":"10.1002\/adfm.201505509","type":"journal-article","created":{"date-parts":[[2016,4,13]],"date-time":"2016-04-13T05:03:34Z","timestamp":1460523814000},"page":"4067-4077","source":"Crossref","is-referenced-by-count":668,"title":["Bifunctional Nickel Phosphide Nanocatalysts Supported on Carbon Fiber Paper for Highly Efficient and Stable Overall Water Splitting"],"prefix":"10.1002","volume":"26","author":[{"given":"Xiaoguang","family":"Wang","sequence":"first","affiliation":[{"name":"International Iberian Nanotechnology Laboratory (INL)  Av.
