WebJul 11, 2024 · The δ 13 C of hydrate-bound CO 2 was lower than that of the residual CO 2 (1.0–1.5‰) in a formation temperature ranging between 226 K and 278 K. The results show that the small difference between equilibrium pressures of ~0.01 MPa in 12 CO 2 and 13 CO 2 hydrates causes carbon isotope fractionation of ~1‰. WebHerein, we describe the catalytic hydrogenation of CO2 to formate with (PNP)Mn–H (PNP = 2,6-bis(di-tert-butylphosphinomethyl)pyridine; Mn = Mn(CO)2). Contrary to the established mechanism for CO2 …
