摘要
人类活动、自然现象和工业来源释放的汞离子(Hg2+)污染了全球的水体,被Hg2+污染的水体在低浓度也就会对人体和环境产生很多不利影响.因此迫切需要一种快速和低成本的检测Hg2+的方法.具有亚纳米结构的金属纳米团簇(MNCs)材料因其特殊的光学、物理和化学性质近年来被广泛用于高选择性和高检测灵敏度传感器的构建.本文将对金属纳米团簇的合成及其用于Hg2+的检测进行综述.
Abstract
Mercuric ion(Hg2+)released from human activities,natural phenomena,and industrial sources is regarded as the global pollutant of world's water.Contaminated water by Hg2+has several adverse effects on human health and the environment even at low concentrations.Therefore,rapid and cost-effective method is urgently required for the detection of Hg2+.Due to its unique optical,physical,and chemical properties,metal nanoclusters(MNCs)have attracted considerable attention for the construction of sensors with high selectivity and sensitivity as a promising material.This review is focused on the synthesis strategies of MNCs and their applications in Hg2+detection.
