Use of Nanostructured Photocatalysts for Dye Degradation: A Review

Among the technologies proposed for wastewater treatment, Advanced Oxidation Processes are viable and technological strategies dyes degradation. Different photocatalytic systems classified in metal oxides alone or combined through hybrid composites immobilized onto supports have been designed various nanostructured shapes their application photodegradation of polluting dyes. This review aims to describe as an environmental threat, photocatalysis effective process remove from water provide overview recent studies using grouped according development. Furthermore, this describes main parameters a system with important role dye photodegradation. Finally, we discuss limitations real industrial applications challenges nanotechnology.
