Photocatalytic degradation of pharmaceutical and pesticide compounds (PPCs) using doped TiO2 nanomaterials: A review

Abstract

Alarming level water pollution is a serious concern in heavily industrialized countries. The development of advanced waste water treatment techniques and their utilization is sought for effective removal of pollutants especially pharmaceutical and pesticide compounds (PPCs). Doped TiO2 nanomaterials mediated photocatalytic degradation of waste water has shown great potential in removing these complex organic pollutants. Improvement in properties of doped TiO2 nanomaterials resulted in the effective utilization of visible light and solar light as light source. Doped TiO2 nanomaterials show great potential to water and energy concerns by fulfilling two key features i.e., effective in removing pollutants which are persistent in nature and cost-effective energy consumption. In this context, doped TiO2 nanomaterials mediated waste water treatment process and its role in water energy nexus is briefly addressed. Application of doped TiO2 nanomaterials against PPCs under different light sources are also discussed in this review.
