Beschreibung
Zusammenfassung:	The invention discloses a method for peroxy titanic acid with visible-light activity for supported photocatalyst. Wherein, preparing clear solution with given concentration by TiSO4 to drip with diluted ammonia into deionized water with given pH value as basic solution; mixing and holding given pH value to form precursor deposition of titanium oxide; continuing to mix for some time; taking solid-liquid separation to the suspending liquid to clean for 3-5 times, dripping some H2O2 peptizer to deposite and obtain the product. The film coating can crystallize and form anatase phase at 150Deg. The membrane layer particle is 10-20 nano sphere or ~20X~100 nano column.
