Selective Glycerol Oxidation by Electrocatalytic Dehydrogenation |
| 초록 |
In this work, we present a simple and direct conversion of glycerol into glyceric acid by anodic oxidation in two different types of electrocatalytic reactors without using stoichiometric chemical oxidants such as oxygen. The two reactor types include 1) an electrocatalytic batch reactor with a three-electrode system with catalyst-coated carbon paper as the working electrode and 2) a continuous flow electrocatalytic reactor based on PEM technology. We also performed non-electrocatalytic glycerol oxidation using a conventional catalytic batch reactor to compare conventional catalytic performances with electrocatalytic reactors. High yield of glyceric acid (79.9 % yield at 91.8 % conversion) was achieved from the electrocatalytic batch reactor using a carbon supported Pt catalyst (Pt/C). A high selectivity of glyceric acid (＞ 80 % selectivity) was also observed in the continuous flow electrocatalytic reactor. The turnover frequency (TOF) for the glycerol conversion was about 10 times higher in the continuous flow electrocatalytic reactor than in the conventional catalytic batch system. |
