Photosensitizing Behavior of Squaraine Dyes in Dye-Sensitized Photocatalysis for Photocatalytic Water or Carbon Dioxide Reduction |
| 초록 |
Red light-sensitized squaraine (SQ) dyes were developed and incorporated into dye-sensitized catalyst (DSC) with the formula of SQ/TiO2/Cat, and their efficacies were evaluated in terms of performance on either water or carbon dioxide reduction. Pt nanoparticles or fac-[Re(4,4′-bis-(diethoxyphosphorylmethyl)-2,2′-bipyridine)(CO)3Cl] were used as each catalytic center within the DSC frame of SQ/TiO2/Pt (Type I) or SQ/TiO2/Re(I) (Type II). In order to convey the potential utility of SQ in low energy sensitization, the following catalytic reductions were carried out under selective lower energy irradiation (＞500 nm). Type I and II showed different catalytic performances, primarily due to the choice of solvent for each catalytic condition: hydrogenation was carried out in H2O, but CO2 reduction in DMF, and SQ was more stable in aqueous acid condition for hydrogen generation than CO2 reduction in DMF. |
