Fundamentals and Recent Progress in Magnetic Field Assisted CO 2 Capture and Conversion.

CO ₂ capture and conversion technology are highly promising technologies that definitely play a part in the journey towards carbon neutrality. Releasing CO ₂ by mild stimulation and the development of high efficiency catalytic processes are urgently needed. The magnetic field, as a thermodynamic parameter independent of temperature and pressure, is vital in the enhancement of CO ₂ capture and conversion process. In this review, the recent progress of magnetic field-enhanced CO ₂ capture and conversion is comprehensively summarized. The theoretical fundamentals of magnetic field on CO ₂ adsorption, release and catalytic reduction process are discussed, including the magnetothermal, magnetohydrodynamic, spin selection, Lorentz forces, magnetoresistance and spin relaxation effects. Additionally, a thorough review of the current progress of the enhancement strategies of magnetic field coupled with a variety of fields (including thermal, electricity, and light) is summarized in the aspect of CO ₂ related process. Finally, the challenges and prospects associated with the utilization of magnetic field-assisted techniques in the construction of CO ₂ capture and conversion systems are proposed. This review offers a reference value for the future design of catalysts, mechanistic investigations, and practical implementation for magnetic field enhanced CO ₂ capture and conversion.
