## Description

- description: The sluggish reaction kinetics of the oxygen evolution reaction (OER)
    and methanol oxidation reaction (MOR) remain obstacles to the commercial promotion
    of water splitting and direct methanol fuel cells. Considering the vital role
    of noble metals in electrocatalytic activity, this work focuses on the rational
    synthesis of Ni-noble metal composite nanocatalysts for overcoming the drawbacks
    of high cost and susceptible oxidized surfaces of noble metals. The inherent catalytic
    activity is improved by the altered electronic structure and effective active
    sites of the catalyst induced by the size effect of noble metal clusters. In particular,
    a series of Ni-noble metal nanocomposites are successfully synthesized by partially
    introducing noble metal into Ni with porous interfacial defects derived from Ni-Al
    layered double hydroxide (LDH). The Ni10Pd1 nanocomposite exhibits high OER catalytic
    activity with an overpotential of 0.279 V at 10 mA/cm2, surpassing Ni10Ag1 and
    Ni10Au1 counterparts. Furthermore, the average diameter of Pd clusters gradually
    increases from 5.57 nm to 44.44 nm with the increased proportion of doped Pd,
    leading to the passivation of catalytic activity due to the exacerbated surface
    oxidation of Pd in the form of Pd2+. After optimization, Ni10Pd1 delivers significantly
    enhanced OER and MOR electroactivities and long-term stability compared to that
    of Ni2Pd1, Ni1Pd1 and Ni1Pd2, which is conducive to the effective utilization
    of Pd and alleviation of surface oxidation.
