Abstract

The health danger generated by dye and textile industries contaminants are of the utmost carcinogenic nature and they pose a hazard to aquatic biota and humans. To resolve this issue, different heterostructure nanomaterials with various probable have been proposed. Among these heterostructures, novel porous 3 wt% Flyash/metal oxides with unique physical, chemical and biological properties, have attracted excessive attention for the degradation of organic dyes from dissimilar solutions. In this research, a new heterostructure of 3 wt% Flyash/ZnMoO4 was successfully synthesized through a fast, simple, and cost-effective hydrothermal technique. The FE–SEM analysis confirms that Flyash/ZnMoO4 structure as nanoplate like microporous structures. HR-TEM study exposed that the synthesized nanomaterial structure was spherical and hexagonal and the particle size (Average size) was well uniformed. Flyash/ZnMoO4 has a higher surface area value (28.65 m2 g−1) than ZnMoO4 (12.42 m2 g−1). The results of the reusability examination exposed that the prepared heterocatalyst was reusable with a degradation efficiency of 96% even after four successive cycles. Moreover, it is recommended and concluded that Flyash/ZnMoO4 prepared from the green hydrothermal method should be the finest economic alternative for textile and dye effluent treatment.
