The environmental benefits of producing formate via electrochemical reduction CO 2 are not straightforward when compared with the conventional, fossil-based approach.

A novel foam-like Ni@Ni(OH)2 composite nanomaterial, synthesized by an organometallic approach, exhibited remarkable robustness and high catalytic performance for CO2 hydrogenation to formate.

New manganese compounds [Mn(HphpzMe)(2)(H(2)phpzMe)(HCO(2))] (1), [Mn(2)(phpzMe)(2)(HphpzMe)(2)(OCH(3))]·2CH(3)OH (2), Na{[Mn(HphpzPh)(phpzPh)(MeOH)(2)](2)}(HCO(2)) (3), [Mn(HphpzPh)(2)(EtOH)(2)]ClO(4)·2EtOH (4) and [Mn(HphpzPh)(2)N(3)] (5) were synthesized and characterized with various techniques. 1, 4 and 5 are mononuclear manganese(III) compounds, 2 is a mixed-valence dinuclear manganese(II...

Context. Hot cores in molecular clouds, such as Orion KL, Sgr B2, W51 e1/e2, are characterized by the presence of molecules at temperature high enough to significantly populate their low-frequency vibrationally excited states. For complex organic molecules, characterized by a dense spectrum both in the ground state and in the excited states, such as methyl formate, ethyl cyanide or dimethyl eth...

Previous studies had demonstrated that Furacin (5-nitro-2-furaldehyde semicarbazone) inhibited the dismutation of pyruvate as well as its conversion to acetylmethylcarbinol by cell-free extracts of both avian (1) and bacterial (2) cells. It was therefore thought desirable to investigate the effect of this compound on the so called phosphoroclastic dissimilation of pyruvate to acetyl phosphate a...

Although obligate syntrophic reactions cannot proceed without hydrogenotrophs, it has been unclear from the literature whether potential improvements are achievable with higher concentrations of hydrogenotrophs. In this study, the relative importance of formate-/H(2)-utilizing and acetate-utilizing trophic groups in the anaerobic degradation of butyrate and propionate was assessed by adding var...

Formate dehydrogenase has traditionally been assumed to play an essential role in energy generation during growth on C(1) compounds. However, this assumption has not yet been experimentally tested in methylotrophic bacteria. In this study, a whole-genome analysis approach was used to identify three different formate dehydrogenase systems in the facultative methylotroph Methylobacterium extorque...

Literature on the subject of glycine metabolism has been reviewed by Weinhouse (1) and by Arnstein (2). The three catabolic pathways for which there has been most support are: (a) the deamination of glycine to glyoxylate, and decarboxylation of the latter to CO2 and formate; in a liver homogenate the formate is oxidized to CO2 and water by catalase and the hydrogen peroxide produced by the acti...

THE ACTIVITY OF REDUCED FERREDOXIN: CO(2) oxidoreductase in Clostridium pasteurianum was correlated with the accumulation of formate in the growth medium. The data indicate that the in vivo function of the enzyme is to mediate formate synthesis rather than its degradation.

Molecular water promoted co-conversion of bicarbonate and methanol into formate over a Pd–Cu catalyst: H2-free approach for reduction.
