Today, environmental contamination is a big concern for both developing and developed countries. The primary sources of contamination of land, water, and air are extensive industrialization and intense agricultural activities. Various traditional methods are available for the treatment of different pollutants in the environment, but all have some limitations. Due to this, an alternative method is required which is effective and less toxic and provides better outcomes. Nanomaterials have attracted a lot of interest in terms of environmental remediation. Because of their huge surface area and related high reactivity, nanomaterials perform better in environmental clean-up than other conventional approaches. They can be modified for specific uses to provide novel features. Due to the large surface-area-to-volume ratio and the presence of a larger number of reactive sites, nanoscale materials can be extremely reactive. These characteristics allow for higher interaction with contaminants, leading to a quick reduction of contaminant concentration. In the present review, an overview of different nanomaterials that are potential in the remediation of environmental pollutants has been discussed.
如今，环境污染是发展中国家和发达国家都十分关注的问题。土地、水和空气污染的主要来源是广泛的工业化和密集的农业活动。有各种传统方法可用于处理环境中的不同污染物，但都存在一些局限性。因此，需要一种替代方法，这种方法有效、毒性小且能提供更好的效果。纳米材料在环境修复方面引起了广泛关注。由于其巨大的表面积和相关的高反应活性，纳米材料在环境清理方面比其他传统方法表现更好。它们可以针对特定用途进行改性以提供新颖的特性。由于大的表面积与体积比以及存在大量的反应位点，纳米级材料可能具有极高的反应活性。这些特性使得与污染物的相互作用更强，从而导致污染物浓度迅速降低。在本综述中，已讨论了在环境污染物修复方面具有潜力的不同纳米材料的概述。
