Antimicrobial and catalytic applications of TiO2 nanoparticles prepared from titanium(IV)-Schiff base complexes as precursor

Abstract

Attempts have been made to synthesis titanium dioxide (TiO₂) nanoparticles using titanium (IV) complexes of Schiff base (TiOL) as a precursor where Schiff base ligand (L) act as a dibasic tetradentate one. TiO₂ nanoparticles were synthesized by the direct calcination of titanium complexes at 500 °C for 3 hours. The analytical tools such as FT-IR, XRD, EDS, and SEM provided evidences in favor of the formation of TiO₂ nanoparticles_. Antimicrobial study showed that all prepared TiO₂ nanoparticles have inhibition capacity on the growth against selected plant pathogenic fungi as well as some selected human pathogenic bacteria. Moreover, these TiO₂ nanoparticles have catalytic capacity for the remarkable degradation (54.0%) of organic dye (Mordent brown 48) as well as industrial dye solutions.
