Effects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity
Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...
متن کاملPreparation and Photocatalytic Properties of Silver Doped Titanium Dioxide Nanoparticles and Using Artificial Neural Network For Modeling of Photocatalytic Activity
This paper presents a study on the preparation method for Ag-TiO2 nano particles. Photodeposition of silver on TiO2 nanoparticles was carried out by adding a desired volume of aqueous AgNO3. Ag-deposited TiO2 catalyst was characterised by XRD, TEM, SEM. The Ag-TiO2 catalyst was evaluated for their photocatalytic activity towards the degradation of Malachite green (MG) under UV irradiation. An a...
متن کاملBlack Hydroxylated Titanium Dioxide Prepared via Ultrasonication with Enhanced Photocatalytic Activity
The amorphous TiO2 derived from hydroxylation has become an effective approach for the enhancement of photocatalytic activity of TiO2 since a kind of special black TiO2 was prepared by engineering disordered layers on TiO2 nanocrystals via hydrogenation. In this contribution, we prepared totally amorphous TiO2 with various degrees of blackness by introducing hydroxyls via ultrasonic irradiation...
متن کاملThe preparation of tubular heterostructures based on titanium dioxide and silica nanotubes and their photocatalytic activity.
Tubular heterostructures based on titanium dioxide (TiO2) and silica nanotubes (SNTs) with high photocatalytic activity have been successfully obtained by a simple combination of an electrospinning technique and a solvothermal process. The as-prepared products were characterized by field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (X...
متن کاملPhotocatalytic Removal of Pseudomonas Aeruginosa from Water Using Titanium Dioxide Nanoparticles and UV Irradiation
Background: Titanium dioxide (TiO2)-mediated photocatalysis has been found to be an efficient method of water treatment and is capable of degrading a wide range of organic pollutants and microbial agents with high efficiency. The microorganism Pseudomonas aeruginosa is resistant to chemicals and UV irradiation. Bacteria which are resistant to UV-induced oxidative damage of the cell membrane are...
