ZnO nano for remediation of methylene blue dye: A short review

Abstract

The presence of dyes in wastewater and water resources is one topic that is getting attention on a global scale. In the present decade, dye-based categories have seen vast development due to the rising need for garments by the increase in population. Mostly used dye in textiles is Methylene blue, which gives dye outflow contamination. It is dangerous and very risky for the surroundings. There are countless sources of methylene blue dye and their adequate medical care methods are inscribed in this present review. The multifunctional ZnO nanomaterial is more effective as a semiconducting photocatalyst than other materials because of its low cost, eco-friendliness, structure-dependent characteristics, and complete mineralization of pollutants. Among nanoparticles photocatalysts, ZnO have shown major capability for photoactive methylene blue deterioration. These metal oxides nanoparticles are the best perfect matter for abolishment of water contaminants, like materials are connected to the attributes of purity, malleability, adaptability, productivity and are highly reactive. The structure of methylene blue dye is highlighted and health impact as well as their effect environment are also discussed. Taking account of all these crucial aspects, the recent advances for remedy of cationic dyes methylene blue by applying ZnO nano is spotlighted in this current review.
