Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts.

ABSTRACT: Developing nonprecious, high-efficiency, and durable electrocatalysts for H₂ evolution in acidic media is highly desirable. Extensive research has focused on improving electrocatalyst activity through techniques like defect engineering, composite formation, and doping. Here, nickel-cobalt phosphide (NiCoP) nanorods' electrocatalytic activity enhancement by applying an external magnetic field is reported. The nanorods are synthesized via a simple hydrothermal method. When coated onto carbon paper, the NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm^-2. However, under a low magnetic field of 2000 G, the overpotential reduced to 62 mV at 10 mA cm^-2 in 0.5 M H₂SO₄, demonstrating that the external magnetic field positively affe
