Synthesis, characterization and investigation of photocatalytic activity of nano-titania from natural ilmenite with graphite for cigarette smoke degradation

Titanium dioxide (TiO2) nanoparticles and TiO2 with recycled graphite (TiO2/G) nanocomposite have been successfully synthesized by alkaline fusion method using synthetic rutile for measuring the degradation time of the cigarette smoke under the visible light irradiation. In this work, the synthetic...
