Formic acid dehydrogenation by [Ru(η⁶-benzene)(L)Cl] catalysts: L = 2-methylquinolin-8-olate and quinolin-8-olate

Abstract

The [Ru(η6-benzene)(L)Cl] (complex 1, L = 2-methylquinolin-8-olate and complex 2, L = quinolin-8-olate) complexes were synthesised and employed for the dehydrogenation of the formic acid (FA) in the presence of...

Formate dehydrogenase activity by a Cu(ii)-based molecular catalyst and deciphering the mechanism using DFT studies

“…S9 †). [40][41][42] Various concentrations of acid, base and catalyst, as well as various temperatures, were used to investigate the catalyst for dehydrogenation. At a constant temperature of 50 °C, the reaction rate was reliant on the concentration of the substrates and catalysts.…”

“…manometer, we have evaluated some previously described catalysts under comparable conditions. [40][41][42] A differential manometer is a pressure gauge that shows the disparity between the reference and working portions. Jacketed cells were utilized as the reference and working compartments at constant temperatures.…”

“…Recently, our group reported the dehydrogenation of formic acid using Rubased homogeneous catalysts using manometry and gas chromatography. [40][41][42] To explore the non-noble metal-based catalysts for formic acid dehydrogenation, we diligently investigated the catalytic efficiency by employing a Cu(II) complex with a polypyridyl ligand. Herein, the dehydrogenation of FA has been depicted utilizing a novel catalyst [Cu(N3Q3)Cl]Cl (N,N-bis(quinolin-8-ylmethyl)quinolin-8-amine = N3Q3), and the mechanism has been deduced via DFT studies.…”

Reviews on Homogeneous and Heterogeneous Catalysts for Dehydrogenation and Recycling of Formic Acid: Progress and Perspectives

“…Solakidou 31 et al found that catalytic complexes containing two ligands (phosphine and Schiff-base ligand) were significantly more efficient in producing H 2 from formic acid than 32 They also explain that the hydrogen pressure generated in the presence of triethylamine in isotonic conditions determines the thermodynamic equilibrium and thus the conversion of formic acid. 33 The complexes Ru(Z 6 -benzene)(L)Cl] (complex 1, L = 2methylquinolin-8-olate/complex 2, L = quinolin-8-olate) were synthesized by Vatsa 34 et al for the FADH in the presence of sodium formate (SF). The catalytic activity of the FA/SF solution at different temperatures and concentration ratios was also studied.…”
