“…In particular, some papers, including those published in high-profile journals, discuss the feasibility of charge-transfer steps only, the thermodynamics of which can be favourably adjusted by "applying" an increasingly (sometimes unrealistic) negative potential, but ignore the very significant energy barriers, of the order of a few eV, for other steps such as N 2 adsorption or NH 3 desorption, which do not depend on the potential. For example, theoretical data of this kind appear in publications 3,23,29,40,41,51,55,82,92,97,105,109,112,116,122, and 123 in Supplementary Table 1. Significant disagreement between the theoretically predicted potentials required for the NRR with those reported experimentally is also not uncommon.…”
