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

ChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic
