Quality Control of Ruthenium(III) chloride xhydrate. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Ru nanoassembly catalysts for hydrogen evolution and oxidation reactions in electrolytes at various pH values.
Here, in an effort to prepare Ru-based metal organic frameworks, the authors developed a one-step solvothermal synthesis for Ru nanoassembly catalysts, which consist of ∼4 nm Ru nanoparticles well dispersed on amorphous carbon (Ru/C). The Ru/C catalyst obtained from a mixed solvent of H2O and CH3CH2OH (Ru/C-H2O/CH3CH2OH), featured a chain-like porous structure, provides Pt-like catalytic properties with low overpotentials at -10 mA cm-2 for the hydrogen evolution reaction (HER) within a wide range of pH values, i.e., 35 mV in 0.5 M H2SO4, 53 mV in 1.0 M KOH, and 93 mV in 3.5 wt% NaCl. Ru/C is also an efficient hydrogen oxidation reaction (HOR) catalyst at all pH values. In the alk. media, Ru/C-H2O/CH3CH2OH achieves a mass activity of 41.1 mA mg-1 at an overpotential of 50 mV and a high exchange c.d. (0.65 mA cm-2). The work provides a facile strategy to synthesize highly active Ru/C catalysts for bifunctional HER and HOR electrocatalysis.
