Splitting System

H 2 production in a water-acetonitrile solution containing iodide as an electron donor was investigated over dye-sensitized Pt∕TiO2 photocatalysts under visible light irradiation, as a potential water-splitting system based on an iodide redox mediator. The rates of H2 evolution decreased with increasing proportion of water in the solutions, because of a decrease in the energy gap between the redox potential of I3−∕I− and the highest occupied molecular orbital levels of the dyes, which decreases the efficiency of electron transfer from I− to dye.

Splitting System

H2 production from a water-acetonitrile mixed solution containing iodide electron donor was investigated over dye-sensitized Pt/TiO2 photocatalysts under visible light irradiation, as a part of water splitting system using iodide redox mediator. The rates of H2 evolution were decreased with the increase of the water ratio in the mixed solutions, because of the decrease in energy gap between the redox potential of I3−/I− and the HOMO levels of the dyes, which lowing the efficiency of electron transfer from I− to dye.

Catalytic Asymmetric

A hybrid system accomplishing cooperativity between an organophotoredox acridinium catalyst and a chiral chromium<br>complex catalyst was developed, enabling the unprecedented exploitation of unactivated hydrocarbon alkenes as precursors to chiral allylchromium nucleophiles for the asymmetric allylation of aldehydes. The reaction proceeded under visible light irradiation at room temperature and with high functional group tolerance, affording the corresponding homoallylic alcohols with up to >20/1 diastereomeric ratio and 99% ee. The addition of Mg(ClO4)2 elicited profound enhancement of both reactivity and enantioselectivity.
