Selective electrocatalytic conversion of nitrogen species requires control over proton and electron transfer. Here, independent optimization of the driving force for proton transfer is realized through the use of MoS2 phases with different pKas, allowing high selectivity for NO, N2O, N2 and NH4+ to be achieved by varying the applied potential.
