Synthesis of TiO2NPs with agricultural waste for photocatalytic and antibacterial applications

Abstract

Titanium dioxide (TiO2) nanostructures with palm trunk mince were deposited via hydrothermal technique. The crystalline structure of TiO2 has two phases anatase and rutile, which analyzed by X-ray diffraction (XRD). TiO2 NPs morphology were examined by field-emission scanning electron microscopy, which revealed that product has hexagonal nanobelts, nanorods, and nanowires. Photocatalyst activates of TiO2 were studied on degradation of methylene blue dye (MB) under UV irradiation, MB absorption decrease with increasing the irradiation time, which optimum degradation showed with nanowires shape comparable with nanorod and nanobelts shapes. The antibacterial study clearly indicates that the palm trunk extract mediated of TiO2 NPS exhibit the excellent antimicrobial activity.
