摘要

MXenes(Mn+1XnTx)是二维(2D)材料的一个子类,具体包括过渡金属碳化物、氮化物和碳氮化物。它们具有优异的电催化和光催化特性,非常适合用于检测和去除水环境中的污染物。由于它们具有高比表面积和卓越的性能,因此被广泛应用于催化、传感和吸附等领域,以消除污染并减轻其不利影响。为了阐明二维 MXene 的结构,我们采用了不同的表征技术,如 XRD、SEM、TEM、紫外-可见光谱和拉曼光谱。在对水体系中的有害污染物进行电化学传感时,使用了多种电分析技术,包括差分脉冲伏安法、安培法、方波阳极剥离伏安法等,测量了电流对施加电位的响应。本综述全面论述了 MXene 的结构模式、合成、特性及其在电化学检测氢醌、苯酚、邻苯二酚、汞和铅等致命污染物中的应用。这篇综述将有助于批判性地理解 MX 烯的合成方法和在去除环境污染物方面的应用。

2D MXene-Based Nanoscale Materials for Electrochemical Sensing Toward the Detection of Hazardous Pollutants: A Perspective.

MXenes (Mn+1XnTx), a subgroup of 2-dimensional (2D) materials, specifically comprise transition metal carbides, nitrides, and carbonitrides. They exhibit exceptional electrocatalytic and photocatalytic properties, making them well-suited for the detection and removal of pollutants from aqueous environments. Because of their high surface area and remarkable properties, they are being utilized in various applications, including catalysis, sensing, and adsorption, to combat pollution and mitigate its adverse effects. Different characterization techniques like XRD, SEM, TEM, UV-Visible spectroscopy, and Raman spectroscopy have been used for the structural elucidation of 2D MXene. Current responses against applied potential were measured during the electrochemical sensing of the hazardous pollutants in an aqueous system using a variety of electroanalytical techniques, including differential pulse voltammetry, amperometry, square wave anodic stripping voltammetry, etc. In this review, a comprehensive discussion on structural patterns, synthesis, properties of MXene and their application for electrochemical detection of lethal pollutants like hydroquionone, phenol, catechol, mercury and lead, etc. are presented. This review will be helpful to critically understand the methods of synthesis and application of MXenes for the removal of environmental pollutants.

期刊介绍: Critical Reviews in Analytical Chemistry continues to be a dependable resource for both the expert and the student by providing in-depth, scholarly, insightful reviews of important topics within the discipline of analytical chemistry and related measurement sciences. The journal exclusively publishes review articles that illuminate the underlying science, that evaluate the field''s status by putting recent developments into proper perspective and context, and that speculate on possible future developments. A limited number of articles are of a "tutorial" format written by experts for scientists seeking introduction or clarification in a new area. This journal serves as a forum for linking various underlying components in broad and interdisciplinary means, while maintaining balance between applied and fundamental research. Topics we are interested in receiving reviews on are the following: · chemical analysis; · instrumentation; · chemometrics; · analytical biochemistry; · medicinal analysis; · forensics; · environmental sciences; · applied physics; · and material science.
