TiO2-mediated DSPC system was the most reliable inorganic foundation, and, therefore, much effort has been exerted on engaging molecular visible photosensitizers as well as photocatalysts onto the platform. The basic process of photocatalysis is initiated by the visible-light absorption by organic/organometallic dyes, followed by the charge separation and interfacial electron transfer (ET) toward catalytic center occurring on the TiO2 semiconductor surface. These reactions primarily occur at the interface between molecular functional components (diverse types of organic/organometallic photosensitizers and molecular Re(I)/Mn(I)/Ru(II) reduction catalysts) and semiconductor (mainly well-defined n-type TiO2). Herein, we report the details of the interfacial ET process between components and discuss the structure-activity relationships based on the relative excited-state energy levels of components. |
