Energy transfer on a two-dimensional antenna enhances the photocatalytic activity of CO 2 reduction by metal-organic layers

Excited state energies on a two-dimensional light-harvesting metal-organic layer (MOL) are efficiently transported to Re- and Ir-based reaction centers for converting CO2 to CO or HCOOH. Such energy transfer enhances the photocatalytic CO2 reduction activity because it enables multiple photo-electron injections in a short time period in the photocatalysis.
