Nitrogen Fixation: Spontaneous Atomic Ruthenium Doping in Mo2CTX MXene Defects Enhances Electrocatalytic Activity for the Nitrogen Reduction Reaction (Adv. Energy Mater. 25/2020)

In article number 2001364, Yongwen Tan and co-workers develop single-atomic ruthenium modified Mo2CTX MXene nanosheets as an efficient electrocatalyst for artificial nitrogen fixation under ambient conditions. Operando XAS studies reveal that single-atoms of ruthenium anchored on Mo2CTX MXene nanosheets act as important electron back-donation centers for N2 activation, thus greatly accelerating nitrogen activation and further hydrogenation.
