Mol. catalysts help overcome the kinetic limitations of H2O oxidation and generally result in faster rates for H2O oxidation than do heterogeneous catalysts. However, mol. catalysts typically function in the dark and therefore require sacrificial oxidants such as Ce4+ or S2O82- to provide the driving force for the reaction. In this Communication, covalently anchoring a phosphonate-derivatized complex, Fe(tebppmcn)Cl2 (1), to WO3 removes the need for a sacrificial oxidant and increases the rate of photoelectrochem. H2O oxidation on WO3 by 60%. The dual-action catalyst, 1-WO3, also gives rise to increased selectivity for H2O oxidation in pH 3 Na2SO4 (56% on bare WO3, 79% on 1-WO3). This approach provides promising alternative routes for solar H2O oxidation In the experiment, the researchers used many compounds, for example, (4-Bromopyridin-2-yl)methanol (cas: 131747-45-0Quality Control of (4-Bromopyridin-2-yl)methanol).
(4-Bromopyridin-2-yl)methanol (cas: 131747-45-0) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Quality Control of (4-Bromopyridin-2-yl)methanol
