General description

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.

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.
