Magnetic field assisted photocatalytic CO2 reduction

Abstract

This paper reviews the recent progress in magnetic field assisted photocatalytic carbon dioxide (CO2) reduction. With the intensification of global warming and environmental pollution, reducing greenhouse gas emissions, especially CO2, has become a global challenge. Photocatalysis technology has received a lot of attention for its potential in environmental governance and energy conversion. The magneto-thermal effect, negative magnetoresistive effect, Lorentz force and spin polarization were used to improve the photocatalytic efficiency. Then, the mechanism of magnetic field assisted photocatalysis and its application in CO2 reduction are introduced in detail. By analyzing the influence of magnetic field on the separation and transport of photogenerated charge, and the role of magnetothermal effect in the photocatalysis process, this paper summarizes the significant advantages of magnetic field assisted photocatalysis technology in improving the efficiency of CO2 reduction. Finally, this paper presents the challenges and future research directions in this field, including in-depth understanding of the specific mechanism of magnetic field effect, optimization of photocatalytic material design, and exploration of multi-field synergies, with a view to promoting the widespread application of magnetic field assisted photocatalysis technology.
