Synthesis of Mixed-Phase TiO2 for Treatment of Organic Pollutants in Wastewater
Due to the population boom, rapid industrialisation, urbanisation and excessive use of fertiliser in the agriculture sector, water pollution has become a serious issue in developing countries like India. Public health and the health of live stocks and crops are in danger due to the recent water pollution. To deal with the problem, the authors developed a highly effective and environment-friendly TiO2 photocatalyst (metal oxide semiconductor) to remove organic pollutants from water bodies. In the present paper, the author describes the chemical process of synthesis of TiO2 photocatalyst along with the details of the material characterisations. The authors also explain how the synthesis pH and reaction temperature highly affects the prepared sample’s nucleation, growth mechanism and surface characteristics.The results show that the prepared material is effective (efficiency > 99 % in 80 min) in the degradation of organic pollutants (model pollutants - phenol, methylene blue, and antibiotics) from water. The synthesised photocatalyst seems non-toxic, cost-effective and likely to have long-term stability in water media.The prepared photocatalyst could be helpful for the degradation of organic pollutants in wastewater to protect the environment.
