Population outbursts and industrial growth drastically reduced the quality of the environment and food worldwide. An alarming concern has been raised within society due to the paucity of emerging innovative solutions to mitigate the challenges imposed by environmental pollution. Various emerging materials, such as nanomaterials, have been implemented in various fields, including environmental remediation due to their large surface area, superior electrochemical properties as well and greater mechanical strength. MXenes, one of the 2-dimensional (2D) nanomaterials, possess high electron mobility, bending rigidity, and conductivity as compared to other potential nanomaterials. Moreover, surface functionalization of MXenes with abundant oxygen and hydroxyl groups induces adsorption capacity in them. The mechanism underlying MXene-driven environmental remediation majorly involves adsorption and photocatalysis. Soil remediation by MXenes involves the process of immobilization, which delimits the bioavailability of metals and other toxic compounds to the crops, hence elevating the crop productivity along with decreasing the environmental pollution. Thus, MXenes play an important role in achieving agricultural sustainability. Moreover, MXenes have been employed in developing nano-sensors exhibiting high accuracy and precision even with minute amounts of pollutants or other stimuli. As compared to other materials, MXenes are cost-effective; still, experts are conducting interdisciplinary research to enhance the scalability of this material by further reducing the cost and developing a regulatory framework to gain acceptance by society.
