A study on the role of plasmonic TiCT MXene in enhancing photoredox catalysis.

Engineering the spatial separation and transfer of photogenerated charge carriers has been one of the most enduring research topics in the field of photocatalysis due to its crucial role in determining the performances of photocatalysts.

In addition to the band alignment-mediated electron transfer in TiO@CdS-TiCT heterojunctions, the plasmon-induced electric field enhancement of TiCT is found to cooperate with the electron-reservoir role of TiCT to extract photoinduced electrons.

Low-temperature assembly of MXene nanosheets into three-dimensional (3D) robust aerogels addresses the crucial stability concern of the nano-building blocks during the fabrication process, which is of key importance for transforming the fascinating properties at the nanoscale into the macroscopic scale for practical applications.

This elaborate aerogel construction not only suppresses the oxidation degradation of TiCT but also generates porous aerogels with a high TiCT content (87 wt%) and robustness, thereby guaranteeing the functional accessibility of TiCT nanosheets and operational reliability as integrated functional materials.
