摘　　要：The sluggish kinetics of oxygen evolution reaction(OER)have seriously obstructed the industrial application of water electrolysis and rechargeable metal-air batteries.Intrigued by the molecular orbital bonding of O2 in a spin triplet state,magnetic field-assisted strategies are widely explored to boost OER electroctalytic activities such as magnetohydrodynamic(MHD)effect,magnetoresistance effect,magnetothermal effect,and spin effect.Here,we investigated the impact of magnetic fields on ferromagnetic catalysts,demonstrating that magnetic fields enhance OER activity by aligning spins and improving mass transfer;then we proposed reasonable verification methods for spin alignments.Subsequently,the possibilities of both mass diffusion and surface conditions besides the spin effect were analyzed sufficiently.Finally,we highlighted the importance of distinguishing spin effects from MHD influences.
