Recent Progress of Magnetic Field Effect on Catalysts

Dear Colleagues,

Developing new strategies to advance the performance of catalysts is crucial to mitigating multiple contemporary technological challenges. In recent years, research on the intersection of magnetic fields and catalysis has attracted increasing attention, and magnetic field-enhanced catalysis has been employed as a frontier and novel strategy to further improve conventional catalysts' activity, selectivity, and overall efficiency. The unique magnetic field effects in the catalytic process, including the magnetothermal effect, magnetohydrodynamic effect, Lorentz forces, Kelvin forces, Maxwell tension, and spin polarization, can accelerate the reaction rate, relieve the adhesion of bubbles on the electrode, promote the mass transfer, and change the reaction pathway. This results in significantly increased catalytic activities in the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER), the CO₂ reduction reaction, etc. On the other hand, when a magnetic field is employed in a catalyst synthesis system, the specific structures, such as the morphology, exposed crystal plane, surface electronic structure modulation, and electron spin state, will be adjusted, which can also promote the improvement of catalytic performance. Although considerable progress has been achieved in magnetic field-mediated strategy, there is still much space for future combinations of catalysts with magnetic fields.

This Special Issue of Magnetochemistry aims to publish a collection of research contributions illustrating the recent progress in all aspects of the magnetic field-mediated strategy on catalysts' performance in the topics listed below.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs).
