Abstract
Bi promoted Pd/C catalyst (Bi-Pd/C) was prepared and evaluated for glucose oxidation. Reaction rate depends on Bi and Pd ratio on activiated carbon. Best promotion effect was got when PdCl2 to Bi(NO)3•5H2O weight ratio was 1 to 3 during catalyst preparation. Compared with other noble metal catalyst, the reaction time was shortened and Bi prevented Pd/C deactiviation during this reaction. The reaction cycles for this catalyst was increased compared to Pd/C catalyst alone. Through XPS analyzation, Bi and Pd was observed to be formed on the surface of activiated carbon particles. This catalyst can be used for industrial process to oxidize glucose to sodium gluconate.
Key words: Glucose oxidation, synthesis, sodium gluconate, Bi-Pd/C catalyst.
