Abstract

Modern research findings for the interaction of two-dimensional molybdenum disulfide (primarily in the nanocrystalline state) with water and air moisture were analyzed. Studies focusing on water intercalation/deintercalation processes and mechanisms in nanocrystalline d-transition metal dichalcogenides (TMDs, mainly 2D MoS2) are at their initial stage. Intercalated water was found to significantly influence the multifunctional properties of 2D MoS2 nanostructures and microsized powders. The need for interdisciplinary studies of 2D TMD nanostructures intercalated with water through complex mechanisms was justified. In particular, the studies should include the development of intercalation/deintercalation nanotechnologies, establishment of interrelationships between the intercalation processes/mechanisms and the state of actual surfaces and features of actual nanostructures, determination of differences in intercalation processes and mechanisms for various semiconductor and metallic nanostructures, and design of multifunctional low-dimensional van der Waals nanomaterials with controllable properties based on nanosized 2D/nD heterostructures (n = = 0, 1, 2, 3) intercalated with water. Promising applications for 2D MoS2 nanostructures intercalated with water are as follows: nanotechnologies of heterostructures with abnormal water properties, tribological characteristics of solid lubricants with moisture present, nanotechnologies using water or aqueous solutions, sorbents and photocatalysts for water purification, electro(photo, piezo)catalysts for the production of hydrogen and oxygen through water electrolysis, as well as hydrovoltaic effects, air humidity sensors, biosensors, and disinfection agents (COVID-19 pandemic).

二维二硫化钼-水:互嵌过程、新功能特性和应用前景
分析了二维二硫化钼(主要是纳米晶态)与水和空气湿度相互作用的现代研究成果。有关纳米晶二过渡金属二卤化物(TMD,主要是二维 MoS2)中水的插层/脱插层过程和机制的研究正处于起步阶段。研究发现,夹杂水会显著影响二维 MoS2 纳米结构和微粉的多功能特性。通过复杂的机制对二维 TMD 纳米结构与水插层进行跨学科研究的必要性得到了证明。特别是,研究应包括开发插层/脱插层纳米技术,建立插层过程/机制与实际表面状态和实际纳米结构特征之间的相互关系,确定各种半导体和金属纳米结构插层过程和机制的差异,以及设计基于水插层的纳米级 2D/nD 异质结构(n = = 0、1、2、3)的具有可控特性的多功能低维范德华纳米材料。水插层二维 MoS2 纳米结构的应用前景如下:具有异常水特性的异质结构纳米技术、存在水分的固体润滑剂的摩擦学特性、使用水或水溶液的纳米技术、用于水净化的吸附剂和光催化剂、通过水电解产生氢气和氧气的电(光、压)催化剂以及水伏特效应、空气湿度传感器、生物传感器和消毒剂(COVID-19 大流行病)。
