Enhanced Removal of Crystal Violet Dye and Anti-Biofilm Activity of Ti Doped CeO 2 Nanoparticles Synthesized by Phoenix Dactylifera Mediated Green Method

Currently eco-friendly green method is used for the synthesis of biocompatible pure and Ti doped cerium oxide nanoparticles. Various chemical methods have been reported for the synthesis of nanomaterials. In the present work, the green chemistry route was employed for the synthesis of Ti doped CeO2 nanoparticles (nanoceria) by Phoenix Dactylifera fruit extract. Their structural, morphological and optical properties were investigated by XRD, XPS, UV-DRS, GC–MS, FTIR and TEM. Structural analysis confirms the formation of Ti doped CeO2 nanoparticles with particle size ranging from 7 to 9 nm and XPS analysis confirms the presence of Ti+4 ions in CeO2 nanoparticles. It was observed that Ti doped CeO2 nanoparticles (NPs) exhibited the enhanced removal of crystal violet dye and maximum degradation was obtained by 15% Ti doped nanoceria. Antibiofilm activity of Ti doped CeO2 nanoparticles were also investigated against P. aeruginosa PAO1, which shows maximum antibiofilm activity for 20% Ti doped CeO2 nanoparticles.
