Fabrication of Ce doped TiO for efficient organic pollutants removal from wastewater.

Pristine and Ce doped TiO nanoparticles were fabricated for toxic pollutants removal from wastewater. Pristine, 2% Ce and 4% Ce doped TiO photocatalysts were produced via hydrothermal route. 4% Ce doped TiO exhibited 2.41 eV bandgap which is smaller than pure TiO The morphology was also investigated and it was established that doping of Ce ions enhanced the surface roughness and reduced the particle size. The surface area was characterized through BET analysis and 4% Ce-TiO possess higher surface with large pore diameter which helped the photocatalytic activity. The prepared photocatalysts were investigated on reduction of pollutants from wastewater under visible light. Higher efficiency was obtained for 4% Ce-TiO photocatalyst for both model pollutants. The "k" value possessed was also higher for the doped TiO catalyst. These analysis reports the optimum level of ceria doping to enhance morphology, surface area and it increased activity than bare TiO. 4% Ce-TiO will be the potential candidate for efficient wastewater management. The 4% Ce doped TiO photocatalyst provided 77% and 88% on reducing MB and RhB dyes. The dopant has developed higher surface area, morphology and good recombination rate which reduced the toxic pollutants and changed the wastewater to reuse.
