Industrial application of light-driven nanomaterial

Abstract In current scenario, the world is heading through challenging environmental concerns like greenhouse gas (GHG) emission, water security, clean energy, etc. Although numerous alternatives were practiced to counter the issue, a permanent relief was not drawn. As a result, a breakthrough in nanotechnology has laid a pathway for the evolution of light-driven energy materials. Since then they have gained popularity in numerous sectors of industrial application and some of the most demanding are solar cell, water treatment, hydrogen production, CO2 reduction, destruction of war fare chemicals, etc. They easily attracted multiple sectors owing to their sustainable characteristics, durability, and reusability potential over the conventional. Moreover, these materials allow reconstruction flexibility in accordance to the need and demand of the day-to-day world. Although these nanomaterials were seen as solution providers for the most prevailing concerns, majority of the remarkable achievements attained in this field were at bench scale. Hence, this chapter exclusively niches on the robust near and full industrial-scale applications of these nanomaterials for clean energy and environment.
