Synthesis, Characterization and Photocatalytic Application of TiO2, Nd3+, Cu2+ Masked Chitosan Nanocomposite

Abstract

Cu²⁺, Nd³⁺-Doped nanostructure TiO₂-coated Nd³⁺ (TiO₂/Nd³⁺) were prepared by sol-gel method. Titanium dioxide were synthesized by the sol-gel method using tetra n-butyl orthotitanate (TBT) as a precursor. The prepared nanoparticles characterized by XRD, SEM and TEM. The XRD showed that the major phase of nanocomposite is anatase. The morphology of the TiO₂/Nd³⁺/ Cu²⁺/chitosan microsphere was investigated using SEM. The TEM shows that the size of TiO₂/ Nd³⁺/Cu²⁺/chitosan was 8-10 nm. Moreover, particles shape were spherical. Acid red 151 removed photochemically by adding TiO₂/Nd³⁺/Cu²⁺/chitosan nanoparticle and H₂O₂ in the presence of the UV radiation. The results show that the kinetics model reaction in presence of catalyst followed from pseudo-second order equation presented by Blanchard.
