D-band frontier, the weight of d-band in [−1.0 eV, 1.0 eV of Pt single atoms, is correlated with the HER activities of Pt 1 /TMDs, which may be a new HER descriptor of Pt single-atom catalysts. • A new descriptor, d-band frontier ( d f ), was developed to estimate the intrinsic HER activity of Pt single-atom catalysts. • d f descriptor highlights the contribution of d-band in [–1.0 eV, 1.0 eV to the HER of Pt single-atom catalysts. • d f was exactly correlated with the |ΔG H | of Pt single atoms on TMDs and other supports (e.g., C 3 N 4 , C, MoO 3 , and CoO). • Systematic experiments demonstrated the rationality of the proposed d f descriptor. Hydrogen evolution reaction (HER) is crucial for achieving sustainable development and carbon neutrality, and thus demands efficient catalysts, which necessitates fundamental theory to relieve trial-and-error experiment. To fast screen HER candidates, most studies focus on d-band center ( ε d ) associated with the Gibbs energy of H adsorption (Δ G H ). Unfortunately, ε d rule is not applicable to Pt single atoms on transition metal disulfides (Pt 1 /TMDs) because of the additional contributions from p states of S atom. Here, we propose a new HER descriptor — d-band frontier ( d f ) by defining the weight of d-band in the energy range of [−1.0 eV, 1.0 eV of Pt single atoms. This d f is exactly correlated with the Δ G H of Pt 1 /TMDs, and thus perfectly describes the structure–activity relationship, as validated by systematical experimental evidences. Moreover, this d f descriptor can be extended to Pt single atoms anchored on other supports (e.g., C 3 N 4 , C, MoO 3 , and CoO), indicating its promising generality.
