Abstract
The present invention relates to a photocatalytically active nanoparticulate material. A nanoparticle of the invention is a composite nanoparticle having two crystalline phases: hydrogen titanate and titania, which are uniformly mixed in the nanoparticle. The invention also relates to forming a nanoparticulate composite material by heating a basic titania sol under solvothermal conditions.
