Preparation of nanoporous titania spherical nanoparticles

Journal of Solid State Chemistry, 2013
Abstract Preparation of nanoporous titania particles from well-defined titania–octadecylamine (titania–ODA) hybrid spherical particles with 450 nm in size, which were prepared by the method reported previously (Chem. Commun., 2009, pp. 6851–6853 [39] ; RSC Adv., 2012, vol. 2, pp. 1343–1349 [40] ), was studied.

Different Kinetic Degradation Of Methyl Orange By Nanostructured Titania: Titania Nanotube, Titania Nanofiber, And Titania Nanoparticle

Qatar Foundation Annual Research Forum Volume 2013 Issue 1, 2013
TiO2 is a semiconductor with photo-catalytic properties and is being thoroughly investigated for its use in the degradation of harmful environmental pollutants using photo-catalytic reactions. The effects of TiO2 nanoparticles and different structured TiO2 electrodes on methyl orange degradation using sunlight have been investigated.

Effect of annealing temperature on titania nanoparticles

AIP Conference Proceedings, 2014
Titania polycrystalline samples are prepared by using sol-gel route hydrolyzing a alkoxide titanium precursor under acidic conditions. The as prepared samples are treated with different calcination temperatures. The anatase phase of titania forms when treated below 600°C, above that temperature the anatase phase tends to transform into the rutile phase

Electrochemical performance of granulated titania nanoparticles

Journal of Power Sources, 2004
Abstract The electrochemical performance of Li-ion insertion into electrodes made of various sizes of anatase titania nanoparticles embedded in larger granulated entities (1–10 μm) is investigated. The granules are formed by spray drying of a suspension containing titania nanoparticles made by hydrolyzing titanium tetraisopropoxide (TTIP).

Polymer microspheres stabilized by titania nanoparticles

Materials Letters, 2006
Abstract Polymer microspheres stabilized by titania nanoparticles were synthesized using a two-step Pickering emulsion polymerization process, in which nanosized titania nanoparticles were used as solid emulsifiers and building blocks. It gives a simple but novel route for the fabrication of functional inorganic/polymer hybrid materials with ...

Deposition of Titania Nanoparticles on Spherical Silica

Journal of Sol-Gel Science and Technology, 2003
Titania coated silica nanoparticles were prepared through a sol-gel process using peptized TiO2 nano-sols. The TiO2 sols were obtained by peptization, the process of redispersing a coagulated colloid, and were coated on SiO2 particles by the control of the weight ratio of TiO2/SiO2 and the pH of the mixture in aqueous solution. At pH 4.5 the difference

Functionalized titania nanoparticles for mercury scavenging

J. Mater. Chem., 2007
Mesoporous films based on crystalline TiO2 nanoparticles functionalized with a ruthenium dye are used as efficient mercury [Hg(II)] scavengers. Mercury scavenging from aqueous solutions at room temperature was monitored both optically and by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). In both cases, the scavenging was observed to

High-density polyethylene reinforced with titania nanoparticles

2007
Titania nanoparticles were prepared by means of two different synthetic procedures in order to obtain different particle size (diameter ranging from 20 nm to 350 nm), shapes and morphologies (amorphous or crystalline). Titania nanoparticles were surface modified with octadecylsilane in order to improve their compatibility with respect to polymeric ...
