Equation 13 in the Supporting Information contained a sign error, resulting in the incorrect pKa values reported for (PNP)Ru–CO2 and PNP. The pKa of (PNP)Ru–CO2 should be 26.1 ± 0.4 (not 24.6 ± 0.4). The pKa of PNP should be 29.0 ± 0.4 (not 28.6 ± 0.4). The same incorrect pKa values are reported on page 14322, in the left column, last paragraph for PNP, and in the right column, first paragraph for (PNP)Ru–CO2), and on page 14323, in Table 2, as well as in the SI (Table S3 and Figure S12 caption).

The hydrogenation of CO2 in the presence of amines to formate, formamides, and methanol (MeOH) is a promising approach to streamlining carbon capture and recycling. To achieve this, understanding how catalyst design impacts selectivity and performance is critical. Herein we describe a thorough thermochemical analysis of the (de)hydrogenation catalyst, (PNP)Ru–Cl (PNP = 2,6-bis(di-tert-butylphosphinomethyl)pyridine; Ru = Ru(CO)(H)) and correlate our findings to catalyst performance.
