Magnetic field-assisted photocatalytic CO2 reduction
This study 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 need. Photocatalysis technology has received a lot of attention for its potential in pollution treatment and energy conversion. Initially, this review delves into the magneto-thermal effect, negative magnetoresistance effect, Lorentz force and spin polarization, which are generally used to improve the photocatalytic efficiency. Then, the mechanism of magnetic field-assisted photocatalysis and its application in CO2 reduction are discussed in detail. By analyzing the influence of magnetic field on the separation and transport of photogenerated charges and the role of magnetothermal effect in the photocatalysis process, this review study summarizes the significant advantages of magnetic field-assisted photocatalysis technology in improving the efficiency of CO2 reduction. Finally, the challenges and future research directions in this field, including an 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, are presented.
期刊介绍：
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
