| Outline of Final Research Achievements |
Focusing on the effective utilization of waste glycerin, a biodiesel byproduct, we fabricated an electrode capable of directly oxidizing glycerin. It is known that the catalytic activity of glycerin oxidation using precious metal electrodes decreases due to inactive oxidation products such as carbon monoxide; however, the electrolytic treatment proposed in this study using a palladium electrode improves the electrocatalytic activity. Based on the results of electrochemical measurements and electrode surface observations, we concluded that the modification of the palladium surface with carboxyl-containing oxides enhances the electrocatalytic activity.

| Academic Significance and Societal Importance of the Research Achievements |
本研究においては，グリセリン酸化に適した原子配置を模索するような材料組織面からのアプローチとは異なり，貴金属触媒の表面修飾という観点からのアプローチを行った．貴金属電極の電解処理あるいは有機物吸着による触媒活性向上が可能であることを示すものであり，簡便な方法のみを用いた電極作製に基づく直接型グリセリン燃料電池の開発へと通ずるものと考える．
