Abstract Heterostructured Mo 2 C‐MoO x on carbon cloth (Mo /CC), as a model of easily oxidized electrocatalysts under ambient conditions, is investigated to uncover surface reconfiguration during the hydrogen evolution reaction (HER). Raman spectroscopy combined with electrochemical tests demonstrates that VI oxides are in situ reduced IV , accomplishing promoted HER acidic condition. As indicated by density functional theoretical calculations, terminal Mo=O moieties can effectively bring...
As a type of heterogeneous catalyst expected for the maximum atom efficiency, series single-atom catalysts (SACs) containing spatially isolated metal single atoms (M-SAs) have been successfully prepared by confining M-SAs in pore-nanospaces porphyrinic metal–organic frameworks (MOFs).
