TI  - Anatase formation during the synthesis of mesoporous titania and its 
      photocatalytic effect.
PG  - 10081-6
AB  - Thermally stable mesoporous titania can be synthesized following different 
      synthesis routes. In this paper, mesoporous titania was synthesized applying the 
      evaporation-induced self-assembly (EISA) method. The mesostructured titania was 
      treated with an NH(4)OH solution to increase the thermal stability. The influence 
      of this postsynthesis treatment on the anatase formation was investigated using 
      different initial synthesis conditions. Mesoporous titania was synthesized under 
      both acidic and basic conditions, with hexadecylamine and cetyltrimethylammonium 
      bromide as surfactants. The samples were investigated with FT-Raman to 
      investigate when exactly anatase was formed during the synthesis. It will be 
      shown that the anatase formation depends mainly on the initial synthesis 
      conditions. This study shows that anatase can already be formed before 
      calcination under certain circumstances. Furthermore, the accessibility of the 
      anatase phase influenced the photocatalytic activity.
