Since multilayered MXenes (TiCT, a new family of two-dimensional materials) were initially introduced by researchers at Drexel University in 2011, various MXene-based nanocomposites have received increased attention as photocatalysts owing to their exceptional properties (e.g., rich surface chemistry, adjustable bandgap structures, high electrical conductivity, hydrophilicity, thermal stability, and large specific surface area). Therefore, we present a comprehensive review of recent studies on fabrication methods for MXene-based photocatalysts and photocatalytic performance for contaminant degradation, CO reduction, H evolution, and N fixation with various MXene-based nanocomposites. In addition, this review briefly discusses the stability of MXene-based nanophotocatalysts, current limitations, and future research needs, along with the various corresponding challenges, in an effort to reveal the unique properties of MXene-based nanocomposites.
自 2011 年德雷塞尔大学的研究人员首次引入多层 MXenes（TiCT，二维材料的新家族）以来，由于其独特的性质（例如丰富的表面化学、可调带隙结构、高导电性、亲水性、热稳定性和大比表面积），各种基于 MXene 的纳米复合材料作为光催化剂受到了越来越多的关注。因此，我们对基于 MXene 的光催化剂的制备方法和用于污染物降解、CO 还原、H 2 演化和 N 2 固定的各种基于 MXene 的纳米复合材料的光催化性能进行了全面综述。此外，本综述还简要讨论了基于 MXene 的纳米光催化剂的稳定性、当前的局限性以及未来的研究需求，以及各种相应的挑战，旨在揭示基于 MXene 的纳米复合材料的独特性质。
