Anatase nanocrystallites showing high surface area (∼62 m 2 /g) and good photocatalytic property have been obtained by pyrolyzing at 600°C for 4 h an ammonium titanyl double sulfate precursor (α‐(NH 4 ) 2 TiO(SO 4 ) 2 ) synthesized via a redox approach, that is, by oxidizing an aqueous solution of titanium trichloride (TiCl 3 ) with ammonium peroxodisulfate ((NH 4 ) 2 S 2 O 8 ), followed by reacting with ammonium sulfate ((NH 4 ) 2 SO 4 ).
