Abstract
A double-layered trimetallic phosphide of Ni<sub>12</sub>P<sub>5</sub>–Fe<sub>2</sub>P–NbP is engineered on plasma-treated nickel foam, and its overpotentials for the HER and OER are only 265 and 330 mV at <italic>j</italic><sub>400</sub> respectively, as well as showing a low cell voltage of 1.65 V at <italic>j</italic><sub>100</sub>.
