When coupled with catalytic processes such as the hydrogen evolution reaction (HER), they have the potential to control catalytic efficiency. Herein, we studied the magnetic response of a series of materials as HER catalysts, specifically ferromagnetic Co2VGa, Co2MnGa, and Ni, ferrimagnetic Mn2CoGa, and paramagnetic Pt. We found that all the Heusler compounds exhibit impressively high intrinsic activity. Most importantly, the presence of a magnetic field can change the HER efficiency significantly, regardless of the magnetic state of the catalyst. We observed boosting HER kinetics for ferromagnetic Ni and paramagnetic Pt, and a decrease of efficiency for ferro/ferrimagnetic Heusler alloys. Our calculations suggest that the binding energy between the reaction intermediate and the catalyst can be tailored effectively by controlling the number of transferred electrons. These findings highlight the vital role of magnetic fields in tailoring heterogeneous catalytic reactions that involve adsorption of reactants.
