Direct‐methanol fuel cells (DMFCs) have become a hot research topic in the energy field due to their excellent conversion efficiency and environmental sustainability. Optimization of catalyst preparation strategy is key enhance performance DMFC. In this study, melt quenching employed synthesize Al–Pd–Ag precursor alloy ribbons, self‐supported nanoporous Pd–Ag catalysts with high activity are successfully prepared by precisely controlled dealloying process. The characterized microstructurally tested electrochemically, compared samples without sodium terephthalate addition commercial Pt/C Pd/C catalysts. results, it shown that maximum peak current density methanol electrocatalytic oxidation significantly enhanced 1451.16 mA mg −1 15 mM terephthalate, which about 6.6 times higher than unadded samples, catalytic improved factor 7.7 12.0, respectively, those Pd/C. This remarkable enhancement attributed innovative method, not only refines structure but also achieves significant increase through assistance active self‐supporting structures interfacial synergistic effects between palladium silver.
