abstract = {By means of electrocatalytic tests, surface-science
techniques and density functional theory, we unveil the
physicochemical mechanisms ruling the electrocatalytic
activity of recently discovered mitrofanovite (Pt3Te4)
mineral. Mitrofanovite represents a very promising
electrocatalyst candidate for energy-related applications,
with a reduction of costs by $47\%$ compared to pure Pt and
superior robustness to CO poisoning. We show that Pt3Te4 is
a weak topological metal with the Z2 invariant, exhibiting
electrical conductivity (∼4 × 106 S/m) comparable with
pure Pt. In hydrogen evolution reaction (HER), the electrode
based on bulk Pt3Te4 shows a very small overpotential of 46
mV at 10 mA cm–2 and a Tafel slope of 36–49 mV dec–1
associated with the Volmer–Heyrovsky mechanism. The
outstanding ambient stability of Pt3Te4 also provides
durability of the electrode and long-term stability of its
efficient catalytic performances.},
