Synthesis of Aliphatic Acids from CO2 and Water at Efficiencies Close to the Photosynthesis Limit Using Mixed Copper and Iron Oxide Films |
| 초록 |
The photocatalytic conversion of CO2 and water into value-added chemicals remains a great challenge. This study shows that uniformly mixed copper and iron oxide (CuO/CuFeO2; CFO) bulky heterojunction films are capable of converting CO2 and water into C1−C6 aliphatic acid anions and O2 at a solar-tochemical energy conversion (STC) efficiency close to 3% under simulated sunlight in the absence of any sacrificial chemicals or electrical biases. When the CFO film is simply wired to a Pt foil, C1 (formate, with selectivity of 100%) and O2 are produced at a near-stoichiometric ratio at an STC efficiency of ∼5% via the Z-scheme charge transfer mechanism. The CFO films are durable over 1 week and recyclable over 5 weeks under continuous irradiation. |
