Intriguing and boosting molybdenum sulfide (MoS2)-based materials for decontamination and purification of wastewater/seawater: An upgraded review

[Display omitted] •This review summarizes the modification of MoS2bMats in recent years.•An up-to-date review is conducted on the environmental applications of MoS2bMats.•Potential and challenges of MoS2bMats are outlooked. Water pollution and the shortage of clean water resource are two of the most urgent issues that need to be addressed in the 21st century. Molybdenum disulfide (MoS2) has been currently one of the most intriguing and boosting 2D materials for wastewater treatment and seawater desalination due to its unique characteristics such as high specific surface area, low cost, high visible light absorbance, narrow band gap and convenient functionalization. In this review, recent effective strategies on modification of MoS2-based materials (MoS2bMats) for improving wastewater treatment and water purification have been reviewed comprehensively. This review focuses on summarizing the applications of MoS2bMats in adsorption, photocatalytic degradation and reduction, Fenton-AOPs, PMS/PS-AOPs, wastewater desalination, etc. Finally, the existing gaps, engineering challenges, future research efforts and opportunities of MoS2bMats are discussed and proposed, aiming at providing in-depth guidance for designing more effective MoS2bMats in decontamination and purification of wastewater/seawater.
