AI Article Synopsis
- Supported atomically dispersed metals are effective photocatalysts for converting CO to solar fuels, but they typically rely on rare and expensive materials like platinum and palladium, which also face stability issues.
- Recent research has found that atomically dispersed copper supported on ultrathin TiO nanosheets can effectively reduce CO in an aqueous solution.
- This new copper-based photocatalyst is not only abundant and low-cost but can also be easily recycled, offering a promising step towards sustainable solar fuel technologies.
Article Abstract
Supported atomically dispersed metals are proving to be efficacious photocatalysts for CO reduction to solar fuels. While being atom efficient, they suffer from being noble, rare, and costly (Pt, Pd, Au, Ag, Rh) and lacking in long-term stability. Herein, all of these problems are solved with the discovery that atomically dispersed Cu supported on ultrathin TiO nanosheets can photocatalytically reduce an aqueous solution of CO to CO. The atomically dispersed Cu can be recycled in a straightforward procedure when they become oxidatively deactivated. This advance bodes well for the development of a solar fuels technology founded on abundant, low-cost, nontoxic, atomically dispersed metal photocatalysts.
