Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 366-18-7, Name is 2,2′-Bipyridine, SMILES is C1(C2=NC=CC=C2)=NC=CC=C1, belongs to catalyst-ligand compound. In a document, author is Wang, Chun-Li, introduce the new discover, HPLC of Formula: C10H8N2.
A cobalt complex of bis(methylthioether)pyridine, a new catalyst for hydrogen evolution
A new cobalt complex, [(btep)CoBr2], was produced by the reaction of CoBr2 and bis(methylthioether) pyridine (btep), and its structure has been determined by X-ray crystallography. [(btep)CoBr2] shows good activity for the electroand photocatalytic reduction of water to H-2. As an electrocatalyst, [(btep) CoBr2] can provide 591.9 mol of hydrogen per mole of catalyst per hour (mol H-2/mol catalyst/h) from neutral water under an overpotential (OP) of 837.6 mV. As a co-catalyst in a photocatalytic system, together with CdS nanorods (CdS NRs) (0.14 mg mL(-1)) as a photosensitizer, and ascorbic acid (H(2)A) (0.12 M) as a sacrificial electron donor in an aqueous solution (pH 4.5), [(btep)CoBr2] can afford 9326.4 mol H-2 per mole of catalyst over a 40 h irradiation with blue light (lambda(max) = 469 nm). The highest apparent quantum yield (AQY) is similar to 25.5%. The catalytic mechanism for H-2 production was investigated by several measurements and analysis. (c) 2020 Elsevier Ltd.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 366-18-7 is helpful to your research. HPLC of Formula: C10H8N2.
