Mechanistic details for the aqueous hydrogen evolution reaction (HER) electrocatalyst [Ni(DHMPE)2]2+ (DHMPE = 2-bis(bis(hydroxymethyl)phosphino)ethane) are reported. The proposed 2e– reduced catalytic intermediate [Ni(DHMPE)2] was added to solutions between pH 1 and 5. The two sequential protonation events leading to H2 evolution were monitored by 31P{1H} NMR spectroscopy. The initial protonation event to generate the metal hydride [HNi(DHMPE)2]+ proceeds to completion within 1.5 min. In contrast, significant variation in the pH-dependent rate and reaction progress of the second protonation event to form the H–H bond is observed. The differences are discussed in the context of the free energy of each protonation event, which also de...
