In recent years there has been growing interest in using electrochemical methods for hydrogenation of organic materials. Conventional hydrogenation technologies require elevated temperatures and externally supplied high pressure (2000psi) hydrogen. The same reactions can be performed using an electrochemical reactor at close to room temperature and with no externally supplied hydrogen. For this paper, we will present our research examining a series of aldehydes and ketones, specifically: benzaldehyde, acetophenone, 2-hexanone, pentanal, fructose and glucose. These materials allow us to examine the impacts of different functionalities on reaction kinetics. In addition to examining single compounds, simple mixtures will be examined to better understand the kinetic impacts. These tests are being done in conventional H-Cells with a Nafion separator, as well as in a flow cell with an integrated reference electrode. A series of platinum and copper based catalysts were used in the tests. We have studied novel cell structures and electrode materials to improve the current efficiency for electrochemical reduction of organic species. Promising results have been observed where significant hydrogenation has been found. A description of work conducted and discussion of results will be presented.
