Titania/zinc oxide nanocomposite coatings on glass or quartz substrate for photocatalytic degradation of direct blue 71

► We have coated zinc titanate nanocomposite was coated on glass and quartz substrate. ► We have studied optical properties of composite films. ► We have studied the effect of heat-treatment on the structure evolution. ► We have studied the photocatalytic activity of the nanocomposite toward photodegradation of direct blue 71.
