We report Pd-Co nanoparticles made by straightforward chemical reduction on graphitic carbon nitride (PdxCoy/g-C3N4) with adjustable Pd/Co ratios. The g-C3N4 exhibits well-dispersed domains, according to structural and surface analyses. Performance in alkaline glycerol is controlled by composition: an intermediate Pd/Co ratio (Pd50Co50) exhibits the lowest charge-transfer resistance and stable chronoamperometric currents over similar to 10(3) s, increases activity (mass activity of 4.13 mA mg(Pd)(-1) and current density of 0.285 mA cm(- 2) in CV at 50 mV s(- 1); 0.051 mA cm(-2) in LSV at 5 mV s(-1)), and decreases onset potential (-0.12 V). Compared with other PdxCoy/g-C3N4 catalysts investigated, Pd50Co50/g-C3N4 delivers superior activity and durability, highlighting the critical role of Pd/Co ratio optimization. This enhanced performance arises from the optimal Pd-Co alloying effect, which induces favorable electronic modulation of Pd active sites and improves the adsorption-desorption balance of glycerol oxidation intermediates. These findings demonstrate that Pd/Co ratio engineering on g-C3N4 offers a scalable path to economical, effective anodes for the electrooxidation of glycerol.eninfo:eu-repo/semantics/closedAccessAnode CatalystPDCoGlycerol ElectrooxidationArticle
