Abstract
Direct conversion of solar energy into chemical fuels via semiconducting materials through photocatalytic technology is a sustainable way to tackle the global warming,environmental issue and energy crisis.Tran-sition metal carbides and nitrides(MXenes),a newly emerging class of 2D layered materials,has gained tremendous attention as a noble metal-free co-catalyst for boosting photoreactivity due to its extraor-dinary characteristics like elemental abundance,excellent electrical conductivity,abundant surface func-tional groups,unique hydrophilic behavior and flexible modulation of chemical composition.The rational integration of low-dimensional MXenes in the form of 2D layered structures or 0D quantum dots with diverse semiconducting materials offer more versatile and robust heterostructured-photocatalysts that are applicable in solar fuel generation.Herein,we summarize the recent advances and achievements in the synthesis of low-dimensional MXenes and their application in hydrogen production from water splitting and CO2 photoreduction.A comprehensive discussion of the fundamentals for solar fuel production,syn-thesis strategies and theoretical calculations for MXenes-based photocatalysts are also given.Finally,the existing challenges and further perspectives of MXenes-based nanostructures for efficient solar fuel pro-duction are addressed.
