“…An elegant way to understand in detail the results of these experiments is given by the numerous investigations which have been dedicated to the adsorption of nitrous oxide on metallic surfaces [59][60][61][62][63][64][65][66][67][68][69]. The literature indicates that the ability of transition metal surfaces to dissociate simple molecules (N 2 , O 2 , NO, etc.)…”

“…It is worth to keep in minds that the adsorption process even of small molecules is a complex process. Different NO adsorption geometries are observed, metallic surfaces may undergo reconstructions, and different factors such as the coverage as well as the temperature play a key role [59][60][61][62][63][64][65][66][67][68][69].…”

“…The production of nitrous oxide (N 2 O) by engineered myoglobins is found instead to proceed through a nitrosyl dimer (NO) 2 [8] . More generally, when looking at the mechanistic aspects of the reactions of nitric oxide, either with transition metal (TM) complexes or at surfaces, it is observed that homomolecular reactions involve disproportionation mechanisms covering a variety of pathways and products [9, 10] . In the former case (TM complexes), the atom transfer processes observed at Ni, Cu, Fe, Mn, and Ru centers can involve 3 to 4 NO molecules, yielding N 2 O+NO 2 or N 2 +2 NO 2 , respectively [9] .…”

Disproportionation of Nitric Oxide at a Surface‐Bound Nickel Porphyrinoid

Uncommon metal oxidation states in porphyrinoid cofactors are responsible for the activity of many enzymes. The F430 and P450nor co‐factors, with their reduced NiI‐ and FeIII‐containing tetrapyrrolic cores, are prototypical examples of biological systems involved in methane formation and in the reduction of nitric oxide, respectively. Herein, using a comprehensive range of experimental and theoretical methods, we raise evidence that nickel tetraphenyl porphyrins deposited in vacuo on a copper surface are reactive towards nitric oxide disproportionation at room temperature. The interpretation of the measurements is far from being straightforward due to the high reactivity of the different nitrogen oxides species (eventually present in the residual gas background) and of the possible reaction intermediates. The picture is detailed in order to disentangle the challenging complexity of the system, where even a small fraction of contamination can change the scenario.
