Pd-based nanocatalysts hold significant promise for application in alkaline direct ethanol fuel cells (DEFCs). To address the challenges of low Pd atom utilization and poor reaction kinetics conventional catalysts, a self-etching strategy has been developed to synthesize Pd3Pb1 nanoparticles (NPs) with tunable size abundant tensile strain. The demonstrated markedly enhanced electrocatalytic performance. NPs-1 exhibited current density 2565 mA mgPd–1 oxidation (EOR). Following self-etching, smaller NPs-2 were synthesized, achieving higher 2820 EOR. Even after prolonged cyclic voltammetry (CV) testing, excellent stability. high mass activity is attributed favorable balance between active intermediates blocking species at catalyst interface. This work presents promising constructing alloying degrees, offering highly efficient catalysts cell applications. Moreover, this study provides reliable approach preparing monodisperse controllable morphology through techniques.
