Sonochemical Synthesis of Mesoporous NiTiO3 Ilmenite Nanorods for the Catalytic Degradation of Tergitol in Water

Ilmenite type titanates have, very wide applications in 'various' fields. In this, paper, we report the synthesis of mesoporous NiTiO3 ilmenite nanorods via a sonochemical approach. The method is vety facile and effective allowing the preparation of NiTiO3 nanopartides with a high yield and uniform size distribution. The reaction intermediate and particularly the final product have been well characterized by various analytical tools (IR, XRD, Raman; TEM, BET, XPS). The final NiTiO3 nanopartides can be described as a hierarchical structure Composed of small nanopartides interconnected generating nanoporous rods. In comparison With anatase TiO2 nanopartides, the catalytic removal rate for the pollutant Tergitol (NP-9) by a process combined with zonation is two and half-fold higher in the presence of mesoporous NiTiO3 ilmenite nanorods.
