Lack of environmental sustainability is a vital and growing
problem due to the issues: such as climate change, pollution, and disturbances
associated with biodiversity. A major cause of these environmental threats is
pollutants in the atmosphere.
Semiconducting
metal oxide nanostructures play an important role in developing smart
materials that are well efficient for sensing and simultaneously destroy
harmful chemical contaminants from our environment.
This review article highlights some recent advances of
nano-science in the area of environmental hazardous contaminant detection by
sensing followed by the remediation; focused on water remediation especially
through photo-catalysis
