Chitosan-titanium oxide fibers supported zero-valent nanoparticles: Highly efficient and easily retrievable catalyst for the removal of organic pollutants.

ABSTRACT: Different chitosan-titanium oxide (CS-TiO₂-x, with x = TiO₂ loadings of 1, 5, 10,15 and 20 wt%) nanocomposite fibers were prepared and kept separately in each salt solution of CuSO₄, CoNO₃, AgNO₃ and NiSO₄ to adsorb Cu²⁺, Co²⁺, Ag⁺, and Ni⁺ ions, respectively. The metal ions loaded onto CS-TiO₂ fibers were reduced to their respective zero-valent metal nanoparticles (ZV-MNPs) like Cu⁰, Co⁰, Ag⁰ and Ni⁰ by treating with NaBH₄. The CS-TiO₂ fibers templated with various ZV-MNPs were characterized and investigated for their catalytic efficiency. Among all prepared ZV-MNPs, Cu⁰ nanoparticles templated
