Development of Visible Light-Responsive Sensitized Photocatalysts

Scheme 6

Potential energy diagram of H₂ production from water over dye-sensitized Pt/TiO₂ photocatalysts with I⁻ as an electron donor. HOMO (a) and LUMO (b) energy levels of merocyanine dye derived from CV measurement in DMF solvent containing 0.1 M tetrabutylammonium perchlorate. Reproduced with a perfect scheme copy from [33].
