Abstract

Self-assembled functional dye molecules in mesoporous transition metal oxides have been synthesized directly by Pc (phthalocyanine) molecules doped within hexadecyltrimethylammonium bromide (C16 TMA) micelles assembled with oxide frameworks such as Vanadia (VOX), FeOx, MoO3 and WO3 to produce Pc-doped mesostructured materials. The Pc molecules were heavily doped inside the mesoporous channels and dye's optical absorption were measured. Pc molecules in contact with mesoporous transition metal oxides interfaces are optically excited and provide reductive electrons to water molecules to decompose into hydrogen by visible light exposures.
