Related Products of 15746-57-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II). In a document type is Article, introducing its new discovery.

Water oxidation catalysis by [(bpy)2(H2O)Ru-O-Ru(H2O)(bpy)2]4+ (Ru(III)(OH2)-O-Ru(III)(OH2)) complex was studied in a homogeneous aqueous solution (AS) as well as heterogeneous Nafion membrane (HM) using Ce(IV) oxidant. The initial O2 evolution rate, V(O2) (mol s-1) increased linearly at low complex concentrations under the excess Ce(IV) oxidant, showing that 4-electron water oxidation is catalyzed by one molecule of the complex. The intrinsic catalytic activities, k(O2) (s-1), in the AS and HM were 4.2 X 10-3 s-1 and 2.4 X 10-3 s-1, respectively. These values are much higher than those of well-known metal and metal oxide catalysts. Comparison of catalytic activity for various metal complexes and oxides is presented.
