Abstract

Two-dimensional (2D) materials have garnered a lot of attention in recent times due to their wide applicability in various areas. These materials exhibit a unique combination of structural and chemical characteristics that have shown promising results and have benefitted almost all the scientific fields including environmental science, engineering, material science, food and agriculture, medical and healthcare, information technology, and many more. These emerging materials have undoubtedly provided new perspectives and solutions to many pressing environmental problems such as the production of clean water through photothermal evaporation, nanosensors to detect the presence of pathogens or toxic materials, and gas-separation devices, to name a few, and hope to continue to do so in the future. Graphene and its derivatives have been the subject of research investigations for the last many years, and the majority of the literature is focused on this 2D material. Other members of the 2D group are less explored and discussed, which generates the literature gap in this field. To fill this knowledge gap, a thorough examination of the environmental applications of some of the recently developed 2D materials - aside from graphene - has been discussed. Although many 2D materials have been extensively discussed by various researchers and are reported in the literature, we have focused on transition metal dichalcogenides (TMDs), metal oxides, MXenes, and Xenes. Metal oxide-based nanomaterials such as nanosized iron oxides, manganese oxides, titanium oxides, zinc oxides, cerium oxides, magnesium oxides, zirconium oxides, and aluminium oxides are not present in 2D form yet they play a pivotal role in numerous environmental applications. In the present review, authors have tried to summarize the environmental applications, considering the size, structure, and various properties (molecular, optical, electrical, and magnetic) of these nanomaterials. This study also highlights the fascinating potential of these materials to strengthen our surroundings in the face of contemporary challenges, and may also advance the debate by describing likely future breakthroughs as well as obstacles in the search for sustainable and environment friendly technologies.

二维材料的环境复原力:未来视角
二维(2D)材料由于其在各个领域的广泛适用性,近年来引起了人们的广泛关注。这些材料表现出独特的结构和化学特性的组合,已经显示出有希望的结果,并已受益于几乎所有的科学领域,包括环境科学、工程、材料科学、食品和农业、医疗和保健、信息技术等等。这些新兴材料无疑为许多紧迫的环境问题提供了新的视角和解决方案,例如通过光热蒸发生产清洁水,检测病原体或有毒物质存在的纳米传感器,气体分离装置,仅举几例,并希望在未来继续这样做。石墨烯及其衍生物在过去的许多年中一直是研究调查的主题,大多数文献都集中在这种二维材料上。2D组的其他成员较少被探索和讨论,这造成了该领域的文献空白。为了填补这一知识空白,本文讨论了一些最近开发的二维材料(石墨烯除外)的环境应用。虽然许多二维材料已经被各种研究人员广泛讨论并在文献中报道,但我们主要关注过渡金属二硫化物(TMDs),金属氧化物,MXenes和Xenes。金属氧化物基纳米材料,如纳米级氧化铁、锰氧化物、钛氧化物、氧化锌、铈氧化物、氧化镁、氧化锆和氧化铝,不是以二维形式存在的,但它们在许多环境应用中发挥着关键作用。本文从纳米材料的尺寸、结构、分子、光学、电学、磁性等方面综述了纳米材料在环境方面的应用。这项研究还强调了这些材料在面对当代挑战时加强我们周围环境的迷人潜力,并可能通过描述未来可能的突破以及在寻找可持续和环境友好型技术方面的障碍来推进辩论。
