Abstract

Abstract: MXene-based nanomaterials (MBNs) are two-dimensional materials that exhibit a series of sought after properties, including rich surface chemistry, adjustable bandgap structures, high electrical conductivity, hydrophobicity, thermal stability, and large specific surface area. MBNs have an exemplar performance when applied for the degradation of hazardous pollutants with various advanced oxidation processes such as heterogeneous sonocatalysis. As such, this work focuses on the sonocatalytic degradation of various hazardous pollutants using MXene-based catalysts. First, the general principles of sonocatalysis are examined, followed by an analysis of the main components of the MXene-based sonocatalysts and their application for pollutant degradation. Lastly, ongoing challenges are highlighted with recommendations to address the issues. Graphical abstract: Image 1 Highlights: Pollutants removal by two-dimensional MXene-based nanomaterials (MBNs) was reviewed. Sonocatalytic degradation hazardous pollutants using MBNs was appraised. Sonocatalyst of MBNs intensifies H O ⋅ formation and enhanced pollutants elimination. MBNs increases photon absorption and improves the sonocatalyst efficiency. MBNs have superb electro-conductivity and superior surface chemistry.
