설명

일반 설명

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.

애플리케이션

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.
