The need for fresh and conveniently treated water has become a major concern in recent years. Molybdenum disulfide (MoS) nanomaterials are attracting attention in various fields, such as energy, hydrogen production, and water decontamination. This review provides an overview of the recent developments in MoS-based nanomaterials for water treatment via adsorption and photodegradation. Primary attention is given to the structure, properties, and major methods for the synthesis and modification of MoS, aiming for efficient water-contaminant removal. The combination of MoS with other components results in nanocomposites that can be separated easily or that present enhanced adsorptive and photocatalytic properties. The performance of these materials in the adsorption of heavy metal ions and organic contaminants, such as dyes and drugs, is reviewed. The review also summarizes current progress in the photocatalytic degradation of various water pollutants, using MoS-based nanomaterials under UV-VIS light irradiation. MoS-based materials showed good activity after several reuse cycles and in real water scenarios. Regarding the ecotoxicity of the MoS, the number of studies is still limited, and more work is needed to effectively evaluate the risks of using this nanomaterial in water treatment.
近年来，人们对新鲜且方便处理的水的需求成为一个主要关注点。二硫化钼（MoS）纳米材料在能源、制氢和水净化等各个领域引起了关注。本综述概述了通过吸附和光降解作用用于水处理的基于 MoS 的纳米材料的最新进展。重点关注 MoS 的结构、性质以及主要的合成和修饰方法，旨在实现高效的污染物去除。MoS 与其他成分的结合产生了易于分离或表现出增强的吸附和光催化性能的纳米复合材料。综述了这些材料在吸附重金属离子和有机污染物（如染料和药物）方面的性能。综述还总结了在 UV-VIS 光照射下使用基于 MoS 的纳米材料光催化降解各种水污染物的最新进展。基于 MoS 的材料在经过几次重复使用循环和在实际水场景中表现出良好的活性。关于 MoS 的生态毒性，研究数量仍然有限，需要开展更多的工作来有效评估在水处理中使用这种纳米材料的风险。
