| 英文摘要 | in order to understand the reason for the poor electrocatalytic stability of the pd/c catalyst for formic acid oxidation, the changes in the structure and the electrocatalytic performance of the pd/c catalyst after dipping in the formic acid solution for a certain time were investigated using x-ray diffraction spectroscopy and electrochemical methods. it is found that the relative crystallinity of the pd particles of pd/c catalyst increases from 1. 73 to 3. 34 and the average size decreases from 4.4 nm to 1. 8 nm after dipping in formic acid solution for 15 d. the electrocatalytic activity and stability of the pd/c catalyst for formic acid oxidation decrease. the peak current density of formic acid oxidation decreases from 9. 3 ma/cm(2) to 6. 7 ma/cm(2). it may. be due to the certain dissolution of pd in the pd/c catalyst and the catalytic decomposition of formic acid at the pd/c catalyst. this result may supply a new approach for exploring the reason for the poor electrocatalytic stability of the pd/c catalyst for the formic acid oxidation. |
