Abstract

Pollution of water raises many concerns for the community because these substances are considered hazardous and can be detrimental to the environment. Waste such as dyes and pesticide residues are the most significant contributors to organic pollution. These hazardous and toxic materials must be properly removed from the environment to ensure and protect human health, safety, and the environment. Adsorption and photodegradation are two effective water purification techniques with high efficiency, economy, and ease of operation, promising environmental remediation through efficient energy use. Metal-organic frameworks (MOFs) that combine metal ions with organic ligands have diverse physical and chemical properties, making them excellent materials for removing toxic pollutants. MOFs possess unique structural properties and are utilized in the latest technological advancements for removing pesticides, heavy metal ions, pharmaceutical waste, and dyes. The functionalization, modification, defects, and deformations of adsorbents can improve the adsorption and photocatalytic performance of MOFs. Several essential factors related to MOF synthesis have been studied concerning structural properties, the basis of linker functionalization, the synthetic strategy of MIX-MOF assembly, mixed ligands, and framework defects, which can improve MOF performance in certain areas. Several topics will be discussed in this review, including MOFs, the strategy of using mixed ligands in MOF synthesis, and their application for treating environmental pollution.

采用混合配体策略对 MOF 材料进行结构修饰，以增强其对有机污染物的光催化降解和吸附能力：综述

水污染引起了社会的许多关注，因为这些物质被认为是有害的，会对环境造成危害。染料和杀虫剂残留物等废物是造成有机污染的最主要因素。这些有害和有毒物质必须从环境中适当清除，以确保和保护人类健康、安全和环境。吸附和光降解是两种有效的水净化技术，具有高效、经济、操作简便等特点，有望通过有效利用能源来修复环境。金属有机框架（MOFs）将金属离子与有机配体结合在一起，具有多种物理和化学特性，是去除有毒污染物的绝佳材料。MOFs 具有独特的结构特性，可用于去除杀虫剂、重金属离子、医药废弃物和染料等最新的技术进步。吸附剂的功能化、改性、缺陷和变形可以提高 MOFs 的吸附和光催化性能。与 MOF 合成有关的几个重要因素已得到研究，包括结构特性、连接体功能化基础、MIX-MOF 组装合成策略、混合配体和框架缺陷，这些因素可以改善 MOF 在某些领域的性能。本综述将讨论几个主题，包括 MOF、在 MOF 合成中使用混合配体的策略及其在处理环境污染中的应用。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
