The catalysts were comprehensively characterized by Inductively coupled plasma mass spectrometry (ICP-MS), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), N2 adsorption-desorption, Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDX), and elemental mapping, and electrochemical techniques namely cyclic voltammetry (CV), chronoamperometry (CA), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS). Pd70Bi30/g-C3N4 had the best electrocatalytic performance among the synthesized catalysts, with the lowest onset potential (-0.31 V), the lowest charge transfer resistance, and the highest specific/mass activity (9.60 mA/cm2 and 180.8 mA/mgPd). Pd and Bi's synergistic interaction, the optimal d-band center position, and the efficient dispersion of nanoparticles on g-C3N4 were all credited with the increased activity. These findings show how atomic ratio tweaking and support material selection can be used to create high-performance anode catalysts for direct glycerol fuel cells (DGFCs).eninfo:eu-repo/semantics/closedAccessGlycerol ElectrooxidationGraphitic Carbon NitrideAnode CatalystNanoparticleCharacterizationArticle
