The degradation of environmental quality has become an escalating concern in contemporary society that precipitates multifaceted issues. In response to this challenge and the imperative to restore natural environmental equilibrium, researchers are intensifying their investigations into the utilization of carbon nanotubes (CNTs) for environmental sustainability. CNTs manifest a notable adsorption capacity and superior reactivity, rendering them highly sensitive and selectively responsive to environmental pollutants. The functionalization of CNTs has yielded significant advancements in a diverse array of CNT-based sensors and adsorbents tailored for environmental protection. This review comprehensively explores the varied advantages offered by CNTs across various environmental applications. In addition to presenting the CNT use in air, water, and soil remediation, a particular emphasis is placed on the regeneration of spent CNTs. Drawing insights from the reviewed literature, it is evident that CNTs have been effectively regenerated and employed multiple times, underscoring their considerable potential as a promising material for environmental detoxification. The challenges, perspectives, and future considerations were presented at last to show the current situation and next potentials. This article assumes paramount importance for scientists and technologists seeking robust solutions for air, soil, and water purification challenges.
