Self-Tandem Electrocatalytic NO Reduction to NH3 on a W Single- Atom Catalyst

Kai Chen et al.

Summary: In this study, single-atom W confined in MoO3-x amorphous nanosheets (W1/MoO3-x) with W1-O5 motifs was designed as a highly active and durable NORR catalyst. The dual functions of W1-O5 motifs were revealed through theoretical and operando spectroscopic investigations, which are to facilitate the activation and protonation of NO molecules and promote H2O dissociation while suppressing *H dimerization. This resulted in a self-tandem NORR mechanism of W1/MoO3-x, greatly accelerating the protonation energetics of the NOto-NH3 pathway, and achieving the highest NH3-Faradaic efficiency and NH3 yield rate among reported NORR catalysts.
