Cover Picture: CO2 photoreduction is a sustainable strategy for converting CO2 into high-value solar fuels. However, its complex reaction pathways, kinetics, and thermodynamic challenges limit its application. MXenes, as an emerging two-dimensional material, have become a focus in photocatalysis due to their unique structural characteristics and highly tunable electrical and optical properties. As for the MXenes-based photocatalysts towards CO2 reduction, significant advances have been achieved in this field. This review starts with an introduction to the key thermodynamic and kinetic factors limiting CO2 photoreduction performance. The structural, electronic and optical properties of MXenes will be discussed to highlight their potential applications in CO2 photoreduction. Then, the latest research progress in MXenes-based photocatalysts for CO2 reduction will be summarized from the perspective of the role of MXenes in MXenes-based photocatalysts. Finally, the review concludes with a summary and future perspectives, outlining potential research directions in this rapidly evolving field. This work can serve as a guide for the development of MXenes-based catalysts for photocatalytic CO2 reduction, benefiting researchers working in this potentially game-changing field.
