磁致载流子分离增强光催化机理研究进展
Research progress in mechanism of enhanced photocatalysis by magnetic carrier separation
摘要
Abstract
Certain materials,when exposed to light irradiation,exhibit the ability to undergo electron transitions,resulting in the generation of electron holes.These electron holes,upon separation,produce active substances,thereby realizing the photocatalytic effect,which holds significant promise for addressing the energy crisis and mitigating environmental pollution.To enhance the photocatalytic effect,external fields,such as electric and magnetic fields,are employed for modulation.Among them,magnetic field modulation stands out due to its non-contact nature and simplicity,effectively boosting photocatalytic activity by facilitating the separation of photogenerated carriers.This approach has garnered considerable attention in the field of photocatalysis.In this paper,we comprehensively review the research advancements in magnetically induced carrier separation for enhanced photocatalysis.Subsequently,we delve into the physical mechanisms underlying magnetic field-enhanced photocatalysis,examining how magnetic fields influence solution absorbance,promoting the separation of photogenerated carriers,and regulating the spin-polarization process.Finally,we consolidate and categorize the reaction conditions for magnetic field-optimized photocatalysis,as well as the modulation mechanism of the magneto-thermal effect on photocatalysis,with the aim of providing scientific insights for future enhancements in photocatalytic efficiency.关键词
