Anionic (IO3-) non-metal doped TiO2 nanoparticles for the photocatalytic degradation of hazardous pollutant in water

This work focuses on the structure, morphology and photocatalytic performance of pure TiO2 and IO3--doped TiO2 nanoparticles. The photocatalytic activity IO3--doped TiO2 nanoparticles in the decomposition of monocrotophos (MCP) are illustrated and discussed in comparison with standard Degussa P-25. Furthermore, IO3--doped TiO2 showed high relative photonic efficiency compared with some of the commercial photocatalysts. The obtained results show a significant dependence of the degradation performance on IO3--doped TiO2 nanoparticles’s structural, morphological and composition properties. In particular, smaller particle size, large surface area and the formation of mixed phases of TiO2 by the addition of iodic acid have a beneficial influence to enhance the photocatalytic activity of IO3--doped TiO2 nanoparticles for the degradation as well as mineralization of MCP.
