Magnetic Field Electrocatalysis: Exploring the Synergy Between Magnetism and Electrochemistry
In a recent study conducted by a collaboration of research groups from ICIQ, the intriguing relationship between magnetic fields and electrocatalytic processes has been brought to light. The research delves into the impact of an external magnetic field on the reaction mechanism of the electrocatalytic oxygen evolution reaction (OER), specifically during water electrolysis for green hydrogen production.
The study, published in APL Energy, demonstrates a direct effect of the magnetic field on the OER reaction mechanism, leading to enhanced kinetics at the electrode surface. This effect is attributed to a larger accumulation of the active NiOOH species, facilitating faster reaction rates. Prof. J.R. Galán-Mascarós, Prof. Núria López, and Dr. Bahareh Khezri, along with the Institute of Advanced Materials (INAM), spearheaded this research endeavor.
Unveiling the Mechanism: Experimental Evidence of Magnetic Field Influence
The findings of this study shed light on a phenomenon that has been the subject of much speculation in the field of electrochemistry. While previous reports have hinted at the magneto-electrochemical enhancement, this study provides concrete experimental evidence to identify the origin of this effect. According to Prof. Galán-Mascarós, the results point towards a microscopic origin at the active site of the catalyst, paving the way for further optimization and utilization of this discovery.
