The catalysts at different weight percentages were characterized by inductively coupled plasma-mass spectrometry (ICP-MS), transmission electron microscopy (TEM), x-ray photoelectron spectroscopy (XPS), and x-ray diffraction (XRD) analytical techniques. Chronoamperometry (CA), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) measurements were applied to examine the glucose electrooxidation performance of the catalysts. Among the catalysts, the 7% Ga@PdAgCo(CNT) multi-metallic catalyst provided the best mass activity and specific activity of 231.08 mA/mg Pd and 2.475 mA/cm2, respectively. EIS results revealed that the 7% Ga@PdAgCo(CNT) catalyst has a faster electron transfer rate with low (632 Ω) charge transfer resistance (Rct). Consequently, the 7% Ga@PdAgCo(CNT) catalyst stands out as a potential anode catalyst for direct glucose fuel cells.
