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.

目前，环保的绿色方法被用于合成生物相容的纯钛掺杂的氧化铈纳米颗粒。已经报道了用于合成纳米材料的各种化学方法。在目前的工作中，采用绿色化学路线通过Phoenix Dactylifera果实提取物合成Ti掺杂的CeO ₂纳米颗粒（纳米藻）。通过XRD，XPS，UV-DRS，GC-MS，FTIR和TEM研究了它们的结构，形态和光学性质。结构分析证实了形成的Ti掺杂CeO ₂纳米颗粒的粒径为7至9 nm，而XPS分析证实了Ce ⁺ ₂纳米颗粒中存在Ti ⁺⁴离子。观察到Ti掺杂的CeO ₂纳米颗粒（NPs）表现出增强的结晶紫染料去除能力，并且15％的Ti掺杂纳米氧化铈获得最大的降解。还研究了掺钛的CeO ₂纳米颗粒对铜绿假单胞菌PAO1的抗生物膜活性，这显示了20％掺钛的CeO ₂纳米颗粒的最大抗生物膜活性。
