The three-dimensional (3D) Pd-based nanoflower structures, assembled from two-dimensional (2D) nanosheets, are characterized by their stable and ordered configurations. These structures have been extensively designed as anode materials for fuel cells. However, the exploration of trimetallic nanoflowers with porous architectures remains limited. In this study, we present a straightforward one-step solvothermal method for the synthesis of trimetallic PdCuNi porous nanoflowers (PNFs). Leveraging several unique advantages, such as an open superstructure, high porosity, and enhanced electronic interactions among the trimetals, the resulting PdCuNi PNFs demonstrate significantly improved electrochemical performance, with mass activities reaching 5.94 and 10.14 A/mg for the ethanol oxidation reaction (EOR) and the ethylene glycol oxidation reaction (EGOR), respectively. Furthermore, the PdCuNi PNFs exhibit optimized d-band centers and the most negative onset oxidation potential, indicating enhanced antitoxicity and stability. This study not only provides a novel perspective on the synthesis of 3D porous nanomaterials but also highlights the potential application value of trimetallic nanoalloys in catalysis.
