Synthetic Route of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.
Visible light driven water splitting in a dye-sensitized photoelectrochemical cell (DSPEC) based on a phosphonic acid-derivatized donor-pi-acceptor (D-pi-A) organic dye (P-A-pi-D) is described with the dye anchored to an FTO|SnO2/TiO2 core/shell photoanode in a pH 7 phosphate buffer solution. Transient absorption measurements on FTO|TiO2|-[P-A-pi-D] compared to core/shell, FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D], reveal that excitation of the dye is rapid and efficient with a decrease in back electron rate by a factor of ?10 on the core/shell. Upon visible, 1 sun excitation (100 mW cm-2) of FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D] in a phosphate buffer at pH 7 with 20 mM added hydroquinone (H2Q), photocurrents of ?2.5 mA cm-2 are observed which are sustained over >15 min photolysis periods with a current enhancement of ?30-fold compared to FTO|TiO2|-[P-A-pi-D] due to the core/shell effect. On surfaces co-loaded with both -[P-A-pi-D] and the known water oxidation catalyst, Ru(bda)(pyP)2 (pyP = pyridin-4-methyl phosphonic acid), maximum photocurrent levels of 1.4 mA cm-2 were observed which decreased over an 10 min interval to 0.1 mA cm-2. O2 was measured by use of a two-electrode, collector-generator sandwich cell and was produced in low faradaic efficiencies with the majority of the oxidative photocurrent due to oxidative decomposition of the dye.
