Effect of calcination temperature on physical parameters and photocatalytic activity of mesoporous titania spheres using chitosan/poly(vinyl alcohol) hydrogel beads as a template

•Mesoporous titania spheres were prepared using CS/PVA hydrogel beads as a template.•The titania spheres prepared was mesoporous structure.•The photocatalytic activity of the mesoporous titania spheres calcined at 500°C was highest. Mesoporous titania spheres were prepared by modified sol–gel method...
