Titanium Carbide (TiC) MXene-based Graphitic Carbon Nitride Composites for Energy and Environment Applications

Photocatalytic hydrogen generation is an intriguing renewable energy technique that can be used to alleviate environmental problems and energy challenges. As a result of the intimate interaction between diverse elements, it is vital to investigate the most appropriate photocatalysts employing multi-cocatalysts. Photocatalytic water splitting has been identified as a promising method of generating hydrogen. Designing a catalyst with a high segregation performance of photo-induced carriers is crucial for increasing the pace of hydrogen production. The Schottky junction is thought to be a viable way to improve the spatial charge segregation and transfer of the photocatalytic process. Under visible light exposure, the photocatalytic hydrogen generation yield of the optimized g-C 3 N 4/Ti 3 C 2 composite was more than six times that of pure g-C 3 N 4. In order to better understand the possible photocatalytic mechanism, an MXene component is successfully constructed as a precursor for synthesizing C-TiO 2/g-C 3 N 4 photocatalysts without the inclusion of extra carbon, and the photocatalysts demonstrate significantly increased photocatalytic hydrogen production processes, and the photocatalytic efficacy of various Chl/Ti 3 C 2 T x composition ratios is evaluated.
