Length-tunable Pd₂Sn@Pt core-shell nanorods for enhanced ethanol electrooxidation with concurrent hydrogen production.

ABSTRACT: The electrooxidation of ethanol as an alternative to the oxygen evolution reaction presents a promising approach for low-cost hydrogen production. However, the design and synthesis of efficient ethanol oxidation electrocatalysts remain key challenges. Here, a colloidal procedure is developed to prepare Pd₂Sn@Pt core-shell nanorods with an expanded Pt lattice and tunable length. The obtained Pd₂Sn@Pt catalysts exhibit superior activity and stability for ethanol electrooxidation compared to Pd₂Sn and commercial Pt/C catalysts. By tuning the length of the Pd₂Sn@Pt nanorods, remarkable mass activity of up to 4.75 A mg_Pd+Pt^-1 and specific activity of 20.14 mA cm^-2 are achieved for the short nanorods owing to their larg
