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

With their promising photocatalytic properties, MXenes are quickly becoming a material of choice for MXene-based composites. Catalysis is an area that can greatly benefit from MXenes because of their wealth of characteristics. TiC MXenes, a well-characterized MXene class in the field of photocatalysis, are well-known for their compositional diversity and ability to create a variety of structures with complex surface chemistry. Metal–organic frameworks (MOFs) are one of the most extensively investigated advanced materials among the co-catalysts that are used for MXene-based composites. Pure MOFs are not ideal for photocatalytic hydrogen generation because of their limitations. Despite tremendous efforts toward mitigating the limitations including the stability of MOF materials, little progress has made researchers inclined toward developing hybrid/composite materials. Similarly, pristine MXenes are not so useful in certain photocatalytic applications. TiC MXenes are one of the mostly used MXene types in the domain of catalysis. Hybridization of MOFs with TiC MXene materials is advantageous as the host structure enables the required qualities to be stabilized and improved. Due to that, recently combining MOFs with TiC MXenes has gained the attention of the researchers. This chapter highlights current advances in TiC MXene/MOF composites and hybrids, as well as their photocatalytic water splitting, photodegradation, and CO 2 reduction applications. Comprehensive reviews of current advances in fast emerging TiC MXene/MOF materials for hydrogen generation, photodegradation, and CO 2 reduction are included.
