Recent progression in MXene-based catalysts for emerging photocatalytic applications of CO reduction and H production: A review.

The development of advanced materials for efficient photocatalytic H production and CO reduction is highly recommended for addressing environmental issues and producing clean energy sources. Specifically, MXenes have emerged as two-dimensional (2D) materials extensively used as high-performance cocatalysts in photocatalyst systems owing to their outstanding features of structure and properties such as high conductivity, large specific surface area, and abundant active sites. Nevertheless, there is a lack of deep and systematic studies concerning the application of these emerging materials for CO reduction reaction (CRR) and H production (HER).
