Mineralization of Recalcitrant Pollutants from Wastewater by Solar Nano-photocatalysis

Abstract

In recent years, the application of the process of heterogeneous photocatalytic water purification has gained great attention due to its effectiveness for degradation and mineralization of recalcitrant organic compounds as well as the possibility of utilizing the solar UV and visible-light spectrum. Heterogeneous photocatalysis, supported by semiconductors and solar energy, is considered a promising process to solve the global crisis of energy supply and to alleviate environmental pollution. In recent years, numerous semiconducting materials have been investigated to explore their photocatalytic potentials. This era of scientific revolution demands the fabrication of efficient nanomaterials with the utmost capability of resolving environmental issues to offset increasingly damaging anthropogenic effects. These nanomaterials basically have non-xenobiotic attributes and they are fabricated following particular zero-waste and green methods. Advanced oxidation processes using metal oxide-based materials have played a vital role in the complete mineralization of recalcitrant pollutants from industrial wastewater.
