Abstract

Abstract : This review summarizes the possible synthetic routes, optical and morphological features to explore the 2D/2D interface and mechanism path in 2D/2D MXene/g-C3 N4 nanocomposites for photocatalytic applications. Abstract : Recently, an enormous group of novel two-dimensional (2D) transition metal carbides, carbonitride and nitrides, known as MXenes, have attracted increasing interest owing to their elemental compositions and surface terminations. Accordingly, MXenes derived from the MAX phase, participating as a co-catalyst or supporting material with 2D g-C3 N4 have been used in photocatalytic systems and are effective due to the creation of an interface and Schottky heterojunction, which accelerate the separation of charge carrier pairs for excellent photocatalytic activities. Thus, the combination of 2D/2D MXene/g-C3 N4 can be a tremendous mode to overcome the limitations of individual semiconductors. Encouraged by these features, in this review, we present the latest synthetic strategies for the preparation of 2D/2D MXene/g-C3 N4 nanocomposites and explore the role of MXenes as a support or co-catalyst material considering recent advances in their application including H2 evolution, NO purification, H2 O2 evolution, CO2 reduction, and pollutant degradation. In addition, the mechanism for charge separation in 2D/2D MXene/g-C3 N4 nanocomposites for photocatalytic application is discussed and an outlook for their future perspectives is also outlined. This review also presents the promising research progress in the area of photocatalysis involving MXene/g-C3 N4 materials together with innovative technologies for significant insight into these processes, which can be established in the near future to deal with energy- and environment-related challenges.
