Description

General description

Our titanium(IV) oxide nanopowder is a fine white powder composed of titanium dioxide nanoparticles with an average particle size of 21 nm, resulting in a high surface area of 35-65 m²/g. Two main physico-chemically distinct polymorphs of TiO₂ are anatase and rutile. Anatase has a higher photocatalytic activity than rutile but is thermodynamically less stable.

We are committed to bringing you Greener Alternative Products that adhere to one of the four categories of Greener Alternatives. This is an enabling product that enhances the performance of perovskite fuel cells, facilitating high solar energy conversion and contributing to more efficient energy solutions.

Application

TiO₂ nanoparticles were used to study the photocatalytic hexane vapor degradation. It has been used as a sorbent for arsenic removal. TiO₂ nanoparticles are suitable for remediation of antiseptic components in wastewater by photocatalysis. It has also been used to study adsorption of DNA oligonucleotides by titanium dioxide nanoparticles.
