Sunlight active U3O8@ZnO nanocomposite superfast photocatalyst: synthesis, characterization and application

Sunlight active U3O8@ZnO nanocomposite photocatalyst has been synthesized for the first time using co-precipitation method. The synthesized composite has a particle size ranging from 18 nm to 30 nm with band gap energy of 2.9 eV. The composite photocatalyst is capable of degrading methylene blue completely within 30 min under sunlight irradiation. Therefore, this superfast efficient sunlight-active photocatalyst is very useful in industrial organic waste water treatment.
