Titanium Carbide MXene-Based Perovskites Composites for Energy and Environment Applications

MXenes acting as co-catalysts in conjunction with particular photocatalysts have been utilized in photocatalytic systems to improve photogenerated charge separation, inhibit rapid charge recombination, and convert solar energy into chemical energy. Therefore, MXenes can be coupled with other semiconductors to enhance the performance of the composite semiconductors. MXene-based perovskite materials with a suitable energy band structure and excellent visible-light response are promising photocatalysts for enhancing our knowledge of the various chemical reactions. It was the intimate interfacial interaction that proved to be the most important factor in photocatalytic applications. Heterostructure materials can enhance photocatalytic activity and are promising for CO 2 abatement and pollutant degradation. Therefore, this chapter will mainly be focusing to understand the fundamentals of photocatalysis using MXene/perovskite composites to meet the application requirements. In addition, strategies to further enhance its photoactivity in terms of charge separation efficiency and reduction of the bandgap to meet the application requirements of catalysts onto chemicals have been elaborated. This work provides a new understanding and design platform for perovskite/MXene-based photocatalysts in different applications.
