Abstract

Titanium dioxide-Alginate (TiO₂-Alg) and Zinc oxide-Alginate (ZnO-Alg) nanocomposites were synthesized and their optical, structural, spectral and morphological analyses were carried out by several techniques. The prepared TiO₂-Alg and ZnO-Alg nanocomposites act as a photocatalyst for removal of Rhodamine B (RhB) dye under visible light irradiation. The pseudo first order kinetics was derived according to Langmuir-Hinshelwood (L-H) model.
