A silver-manganese dual co-catalyst for selective reduction of carbon dioxide into carbon monoxide over a potassium hexatitanate photocatalyst with water

A Ag-Mn dual co-catalyst deposited on a K 2 Ti 6 O 13 photocatalyst significantly enhances the photocatalytic CO 2 reduction into CO with an extremely high selectivity of 98% by using H 2 O as an electron donor, owing to the properties of Ag and MnO x species for promoting CO and O 2 formation, resp...

Zusammenfassung:A Ag-Mn dual co-catalyst deposited on a K 2 Ti 6 O 13 photocatalyst significantly enhances the photocatalytic CO 2 reduction into CO with an extremely high selectivity of 98% by using H 2 O as an electron donor, owing to the properties of Ag and MnO x species for promoting CO and O 2 formation, respectively. A Ag-Mn dual co-catalyst can improve the photocatalytic activity of a K 2 Ti 6 O 13 photocatalyst to a great extent for CO 2 reduction to CO by using H 2 O as an electron donor with an extremely high CO selectivity ( S CO = 98%).
