Homogeneous hydrogenation of carbon dioxide and bicarbonate in aqueous solution catalyzed by water-soluble ruthenium(II) phosphine complexes

A Well‐Defined Iron Catalyst for the Reduction of Bicarbonates and Carbon Dioxide to Formates, Alkyl Formates, and Formamides

“…For example, Joó and co-workers obtained a TON of 108 with [{RuCl 2 -(mTPPMS) 2 } 2 ] (mTPPMS = meta-monosulfonated triphenylphosphine) in aqueous solution. [10] An important long-standing goal in chemistry is the development of bio-inspired catalysis and the replacement of noble metal based catalysts, that is, ruthenium, iridium, and rhodium, with nonprecious metals, such as iron, zinc, and manganese. [11] In this respect, an iron-based reduction of carbonates and carbon dioxide constitutes a challenging and highly attractive goal.…”

Recent Advances in Transition Metal-Catalysed Homogeneous Hydrogenation of Carbon Dioxide in Aqueous Media

“…(Laurenczy et al, 2000) In 2003, Joó et al reported the hydrogenation of bicarbonate with [RuCl2(tppms)2]2 (tppms = sodium diphenylphosphinobenzene-3-sulfonate) at 50 °C and 10 bar H2, a TOF of 54 h −1 was obtained. (Elek et al, 2003) Their results suggest that bicarbonate is more reactive than hydrated CO2. Interestingly, in presence of 5 bar CO2 the reaction was about 10% slower than that without CO2.…”

The Virtuous CO2 Circle or the Three Cs: Capture, Cache, and Convert

“…The Ru-and Rh-based systems were found to be active catalysts in both aqueous media and organic solvents. Generally, the production of the formic acid is mediated by an amine which converts the acids into ammonium formate-like reaction intermediates [91,92]. Methanol is one of the most interesting products in terms of large CO 2 conversion volumes.…”
