ABSTRACT

Anatase-type TiO2 particles were formed on a surface of rutile particles by thermal crystallization from amorphous titan oxyhydroxide that was obtained from the aqueous solution of TiOCl2 using urea hydrolysis. Special attention was paid to obtain rutile-anatase composite with reproductive physico-chemical properties by control of synthesis parameters. Catalytic activity of the synthesized composite was studied on photoinduced oxidation of formaldehyde vapours in a flow reactor.
