Abstract
Synthesis of bimetallic phosphide like Pine cone efficient electrocatalyst for the development of water electrolyzers is of significant interest. Herein, NixCoyP catalyst was synthesized via Condensation reflux and phosphating process, and it has a defect rich nanosheet like morphology. The special morphology provided more active toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). NiCoP delivers the current density of 10 mA/cm2 for HER at an overpotential of 226 mV in alkaline. NiCo2P is also highly active toward OER and requires 154 mV to attain 10 mA/cm2. The NiCo2P delivers 10 mA/cm2 current density at a cell voltage of 1.49 V and retains 75% of its initial current density even after 12 h of continuous electrolysis.
