A visible-light harvesting system for CO2 reduction using a Ru(II) -Re(I) photocatalyst adsorbed in mesoporous organosilica.

Ueda Y, Takeda H, Yui T, Koike K, Goto Y, Inagaki S, Ishitani O - ChemSusChem (2014)

Bottom Line: The embedded organic groups absorbed visible light, and the excitation energy was funneled to the Ru units.The energy accumulation was followed by electron transfer and catalytic reduction of CO2 to CO on the Re unit.The light harvesting of these hybrids enhanced the photocatalytic CO evolution rate by a factor of up to ten compared with that of RuRe adsorbed on mesoporous silica without a light harvester.
