| There have been extensive studies on designing molecular systems that can lead to long-lived photochemically generated and spatially separated charge pairs with the goal of solar energy conversion. However, practical performance of such systems will be limited, unless the spatially charge-separated species are used for chemical reactions. We will report on using a zeolite film grown on alumina membrane for charge separation and chemical reaction. Ruthenium oxide was generated in the alumina membrane by thermal decarbonylation of Ru3(CO)12 followed by heating in air. The observed RuO2 was c.a. 10 nm size with a fibrous shape. The catalytic activity of ruthenium oxide for H2 formation from H2O was examined using the well-established photochemical system Ru(bpy)32+-DQ2+-PVS in conjunction with the zeolite membrane. The system successfully demonstrates the effective spatial charge separation through the zeolite membrane followed by reaction of water on the RuO2 to produce hydrogen.
