摘　　要：光催化技术凭借其独特的优势,如利用太阳能作为驱动力、反应条件温和且无需额外添加化学试剂等,成为了当前研究的热点,而其走向实际应用的关键是发展高效、稳定的光催化剂。Aurivillius型层状光催化剂凭借其独特的交替堆叠结构与显著的层间极性差异的结构优势,有效地促进了光生载流子的定向分离与高效传输,从众多光催化剂中脱颖而出。尤为显著的是,其结构中正负交替的极性电荷层分别作为光催化反应还原端与氧化端,实现了反应物分子的精准吸附、高效活化以及反应位点的空间分离,从而显著提升了光催化反应的效率与选择性。本文系统介绍了Aurivillius型层状光催化剂在光催化氧化及还原反应领域的最新研究进展,并深入探讨其改性策略,旨在为该类催化剂在光催化全反应体系中的深入应用提供参考,以促进光催化领域的持续创新与发展。Photocatalysis technology with its unique advantages,such as the use of solar energy as a driving force,mild reaction conditions,and no additional chemical reagents,has become a hot spot of current research,and the key to its practical application is to develop efficient and stable photocatalysts.Aurivillius layered photocatalysts stand out from many photocatalysts by virtue of their unique alternating stack structure and significant interlayer polarity difference,which effectively promote the directional separation and efficient transport of photogenerated carriers.In particular,the alternating positive and negative polar charge layer in its structure serves as the reduction end and oxidation end of the photocatalytic reaction,respectively,to achieve accurate adsorption and efficient activation of reactant molecules and spatial separation of reaction sites,thus significantly improving the efficiency and selectivity of the photocatalytic reaction.This paper systematically introduces the latest research progress of Aurivillius-type layered photocatalysts in photocatalytic oxidation and reduction reactions.It discusses its modification strategies in depth,aiming to provide a solid theoretical basis and research framework for the further application of such catalysts in the photocatalytic total reaction system,to promote continuous innovation and development in the field of photocatalysis.
