A number of anatase derivatives doped with iron, yttrium, and vanadium oxides were synthesized in a pressure reactor at 250°C by the solvothermal method in a solution of anhydrous capronic acid. It was shown that at certain iron and yttrium concentrations the photocatalytic activity of obtained samples exceeds the activity of the titanium dioxide nanopowder Aeroxide^® P25 used as a standard.
