摘要
Two-dimensional(2D)materials,especially transition metal carbides and/or nitrides(MXenes),have aroused extensive research interest in the field of photocatalysis.Specifically,the unique properties of high electrical conductivity,abundant surface functional groups,considerable specific surface area,and excellent photo-thermal effect allow MXenes to play versatile roles in photocatalysis.Herein,the latest and encouraging developments in MXenes-based composite materials for photocatalytic applications in recent two years are reviewed.We first briefly describe the roles of MXenes as a support and co-catalyst to promote the distribution of photocatalysts and facilitate the separation of the photogenerated charge carriers,respectively.Then,the design and fabrication of MXenes-based composite materials for various photocatalytic applications including H_(2) evolution,CO_(2) reduction,environmental remediation,and H_(2)O_(2) generation are comprehensively illustrated.Finally,we point out the challenges and prospects for the future development of MXenes-based composite materials.
