Abstract
Extremely efficient nanomaterials are urgently needed in the field of photocatalysis for solar energy conversion and fuel production applications. MXenes are gaining significant attention as a promising layered material for usage in energy conversion processes. Large surface area, controllable surface functionalities (–OH, –O, and –F), high electrical conductivity, and metallic active sites are the unique properties of MXenes. MXenes used as co-catalysts with other photocatalytic materials and reduce the recombination in photo generated charge carriers which further improve the efficiency of the material. This review summarizes the synthesis of MXenes, their surface modifications, heterojunction schemes and applications in photocatalytic CO2 reduction and H2 production application. Furthermore, several methods for the preparation of MXene-based nanostructures with enhanced photocatalytic activity are also discussed. Photocatalysis involves the generation of photo-generated electrons in semiconductor materials and their effective migration to MXenes for the initiation of photochemical processes at various heterojunctions. This review also explores the underlying processes and basic concepts of photocatalysis at different heterojunction configurations. Lastly, the review presents the challenges and future advancements in MXene based heterojunction for viable renewable fuels.
