New strategies in the preparation of binary g-C۳N۴/MXene composites for visible-light-driven photocatalytic applications

In recent years, g-C۳N۴@MXene photocatalysts have received much attention due to their special composition and excellent properties. MXenes consisting of transition metal carbides, nitrides, and carbonitrides derived from the MAX phase are used as cocatalysts or g-C۳N۴ (GCN) supporting composites in a variety of photocatalytic processes that accelerate the separation of charge carriers with their heterojunction structure. In addition to the high ability of g-C۳N۴@MXene nanocomposite to absorb light, it has high photocorrosion resistance in the processes of hydrogen evolution, wastewater treatment, nitrogen fixation, NO treatment, and oxidation and reduction photoreactions. In this review, the latest developments and new technologies for the manufacture and application of noble metal-free g-C۳N۴@MXene nanocomposite have been discussed and the future perspective has been drawn to deal with challenges related to energy and the environment.In recent years, g-C۳N۴@MXene photocatalysts have received much attention due to their special composition and excellent properties.
