Abstract
Acute water cataclysm on account of eco-noxious anthropogenic exploitation caused massive
setbacks on the global prerequisite of clean water. Subsequently, with the purpose of circumventing
the worldwide unpolluted water deficiency, wastewater treatment technologies have received
extraordinary precedence to disinfect water for a sustainable environment. Presently, diverse, efficient
materials are being used to remove organic/ inorganic noxious substances from wastewater,
among which graphene and its composites have received remarkable attention for water decontamination
technology by virtue of their substantial surface area, mechanical strength, mesoporosity,
nanosheet arrangement and outstanding absorption proficiency for the contaminant. The present review
accentuates the contemporary progresses in the implementation of graphene along with its
composite as a potential adsorbent for the exclusion of pernicious inorganic mixture of miscellaneous
pollutants, as photocatalysts for the breakdown of venomous organic toxins by employing photocatalytic
oxidation. The prospect of graphene and its nanocomposites towards comprehensive water
treatment approaches has been discussed.
Keywords:
Adsorbent, composite, graphene oxide, graphene, photocatalyst, water decontamination.
