Organometallic Ir(III) Complex-Sensitized Ternary Hybrid Photocatalyst for CO2-to-CO Conversion |
| 초록 |
A series of heteroleptic Ir(III) complexes functionalized with the two phosphonic acid (–PO3H2) groups (dfppyIrP, ppyIrP, btpIrP, and piqIrP) are anchored onto Re(I) catalyst (ReP)-loaded TiO2 particles (TiO2/ReP) to build up a new IrP-sensitized TiO2 photocatalyst system (IrP/TiO2/ReP). The photosensitizing behavior of the IrP series was examined in IrP/TiO2/ReP platform for photocatalytic CO2-to-CO conversion. The four IrP-based ternary hybrids showed increased conversion activity and durability than the corresponding homogeneous and heterogeneous mixed systems. Among the four IrP/TiO2/ReP photocatalysts, the low energy light (＞500 nm)-active piqIrP immobilized ternary system exhibited the most durable conversion activity. |
