Preparation of nanocrystalline titanium oxide by decomposition of molecular precursor alpha-(NH4)(2)TiO(SO4)(2)
Hydroxy-free anatase TiO2 nanocrystals (25 nm) with photocatalytic activities higher than that of commercial photocatalyst Degussa P-25, were prepared by nonhydrolytic thermolysis of ammonium titanyl sulfate at 700degreesC for 2 h.
