CO2-to-CO/Formate Reduction of Half-Metallocene Ru(II)(η6-p-cymene) Catalyst and Its Mechanistic Investigation |
| 초록 |
This study details the photocatalytic CO2-to-CO or formate conversion activities of two different photocatalytic systems (IrPE + (p-Cym)RuPE and IrP/TiO2/(p-Cym)RuP) to evaluate the catalytic behavior of homogeneous and heterogenized (p-Cym)Ru(II) catalyst, respectively. A single run photolysis of the mixed homogeneous system (IrPE + (p-Cym)RuPE) in the presence of 16.7 vol % TEOA exhibited a maximal turnover number (TON) of ~800 for 48 h with a high product selectivity of formate (>79%), while the ternary hybrid system with TiO2-immobilized (p-Cym)RuP showed the relatively higher and steady CO2-to-CO and CO2-to-formate conversion activities (a TON of >1660 for 100 h), reflecting the CO2 reduction route bisected by heterogenization of (p-Cym)RuP. |
