General description

Titanium(IV) oxide is a chemically inert and non-toxic semiconductormaterial widely used in the field of photovoltaics and environmentalremediation. Thephotocatalytic activity of anatase is superior tothat of other polymorphs of titanium oxide.

Application

Titanium(IV) oxide can be used as a precursor:
  • To synthesize TiO2/ZnO- calcium alginate photocatalyst for removal of copper from aqueous solutions.
  • To fabricate implantable composite bioelectrode for biosensing applications.
It can also be used as a nanoparticle growth initiator for the anodic modification of microbial fuel cells(MFC) to enhance their performance.

Features and Benefits

  • Higher electron mobility
  • Low dielectric constant
  • Lower ability to adsorb oxygen
  • Higher Fermi level
  • High degree of hydroxylation
  • Superior biocompatibility
  • Corrosion resistance
