主　　题：Anatase {001} and {101} facets H_(2)O_(2)-NH_(3) 

摘      要：Anatase titanium(IV)oxide(TiO_(2))particles with exposed{001}and{101}facets were prepared by hydrothermal treatment of amorphous TiO_(2) with H_(2)O_(2)-NH_(3) *** phase,shape,and size of TiO_(2) particles are found to be greatly dependent on the ratio of H_(2)O_(2)-NH_(3) *** prepared TiO_(2) particles with specific exposed crystal faces show higher photocatalytic activity for acetaldehyde decomposition than commercial spherical TiO_(2) *** result implies that recombination is prevented by spatial separation of redox sites in the particles because of selective migration of electrons and positive holes to specific exposed crystal faces and/or different reactivity of electrons and positive holes on the specific exposed crystal face.
