Magnetic field effects on electrocatalysis have recently gained attention due to the substantial enhancement of the oxygen evolution reaction (OER) on ferromagnetic catalysts. An international team of researchers (Switzerland, Argentina) used a specifically designed magneto-electrochemical system and non-magnetic electrodes to quantify magnetic field effects. They found marginal enhancement in reactions with high reactant availability, such as the OER, whereas substantial boosts exceeding 50% were observed in diffusion limited reactions, exemplified by the oxygen reduction reaction (ORR). According to the researchers their results advanced the fundamental understanding of magnetic fields in electrocatalysis and unveil new prospects for developing more efficient and sustainable energy conversion… read more.
