A stable and efficient porous nickel phosphate (p-NiPO/Ti) electrocatalyst on titanium sheets was developed via electrochemical deposition low-temperature phosphatization. For obtaining the optimal performance of p-NiPO/Ti electrocatalyst, optimized experimental parameters phosphatization were determined by parallel experiments. After preparation, XPS XRD used to validate chemical amorphous structure, with SEM TEM simultaneously validating a distinct nanosheet/nanocluster crosslinked microstructure. In particular, conditions maintained at 300 °C for 10 min, produced demonstrated excellent charge transfer catalytic characteristics in 1.0 M KOH. The electrocatalytic results revealed that stability (~24 h) needs lower HER overpotentials (128 mV mA cm−2 242 100 cm−2) as inputs. This research provides promising strategy which use transition metal materials catalysts alkaline hydrogen production.
