Titanium dioxide photocatalysts co-doped with iron(III) and lanthanum(III) have been prepared through a modified sol–gel method. Doping with Fe3þ resulted in a relatively lower anatase to rutile phase transformation ...

High temperature stable brookite rich titanium dioxide of average crystallite size 20 nm has been prepared by a novel aqueous sol-gel method involving hydroxyethyl cellulose polymer (HEC) as an organic intermediate, wherein ...
