The development of efficient electrocatalysts for the complete oxidation ethylene glycol (EG) is crucial enhancing practicality direct EG fuel cells (DEGFCs). However, significant challenges persist in developing highly active Pd-based catalytic electrodes. In this work, PdIrNi ternary telluride nanospheres (PdIrNiTe-MNSPs) with mesoporous morphology and an amorphous structure were successfully synthesized applied electrocatalytic reaction. Brunauer–Emmett–Teller analysis revealed typical characteristics, a surface area 8.33 m2·g−1 total pore volume 0.055 cm3·g−1, respectively. Transmission electron microscopy characterization showed that outer layer PdIrNiTe-MNSPs entirely structure. Electrochemical tests demonstrated exhibit enhanced specific activity (16.75 mA·cm−2) mass (1372.22 mA·mg−1) reaction (EGOR), achieving 3.17 2.09 times higher than commercial Pd/C, which can be attributed to its unique nanoarchitecture optimized configuration. situ spectroscopy incorporation IrNi, facilitate C-C bond cleavage EG, selectivity (≈93%) oxidizing C1 products, while PdTe-MNSPs glycolic acid EGOR. Taken together, work provides new insights into application nanomaterials electrocatalysis
