Abstract: To improve the electrocatalytic activity of Pd for glucose oxidation, a novel binary Sn-Co oxide promoting Pd catalyst (Pd-SnCoOx /C) is synthesized via facile precipitation and polyol methods. Electrochemical results show that Pd-SnCoOx /C exhibits excellent electrocatalytic performance for glucose oxidation. Compared with Pd/C catalyst, as-prepared Pd-SnCoOx /C catalyst has larger electrochemically active surface area, higher electrochemical activity and superior stability. The high catalytic performance may be attributed to the synergistic effect between binary Sn-Co oxide and Pd nanoparticles, leading to smaller size and higher dispersion for Pd-SnCoOx /C than Pd/C. To further understand the glucose oxidation, the tafel plots, effects of concentrations and scan rates are also investigated.
