PdxRuy/C binary catalysts for glucose electrooxidation

Abstract

PdxRuy/C (x:y=1:2, 1:3, 2:1 and 3:1) electrocatalysts are prepared by a modified pulse microwave assisted polyol method and are studied for glucose electrooxidation in alkaline media. The effects of glucose's concentrations as well as of temperature on the activity of electrocatalysts are also investigated. According to the CV results, the electro-catalytic activity towards glucose electrooxidation of the investigated catalysts has the following order: Pd2Ru/C> Pd3Ru/C > PdRu/C > PdRu2/C > PdRu3/C. It was found that increasing glucose's concentration from 0.02 M to 0.5 M the current increases. Additionally, the increment of temperature enhances glucose electrooxidation until 40°C.
