      abstract     = {While simultaneously highly active and durable catalysts
                      for the methanol-oxidation reaction (MOR) are rare, their
                      performance at device-relevant elevated temperatures has
                      been barely explored. In this work, we design oxophilic
                      Ni-doped Pd nanowire morphology, which can impart multiple
                      catalyst-electrode contacts, achieving a superior MOR mass
                      activity of ∼3.5 A mg–1 and commendable stability with
                      $<0.8\%$ degradation/hour. Through comprehensive studies
                      across varying temperatures and potentials, we reveal
                      significant performance deviations at high temperatures (HT)
                      compared to conventional room-temperature data, as well as
                      stark behavioral contrasts between Pt and Pd. The Pd
                      nanowires exhibit superior resistance to surface oxidation
                      at HT, thereby retaining their high MOR performance with
                      2-fold deviations in activation energy values with varied
                      applied potentials, while Pt barely shows any variation. To
                      corroborate this, we systematically map the
                      temperature-dependent −OH formation vs utilization
                      kinetics and establish a direct correlation with −OH
                      tolerance. Due to superior activation by resisting −OH
                      poisoning, the Pd nanowires widen their theoretical
                      operating potential window by over $180\%$ more than in Pt.
                      While Pd is already recognized for its superior CO
                      tolerance, our study establishes that it is also more
                      resilient to OH poisoning at elevated temperatures, enabling
                      simultaneous high activity and activation.},
