First Time

The electrochemical hydrogenation of levulinic acid in H2SO4 solution at aluminium, lead, graphite and glassy carbon electrodes is studied. The process is identified to proceed selectively to valeric acid. The conversion, selectivity and faradaic efficiency are significantly influenced by the material electrode nature. The levulinic acid hydrogenation at glassy carbon is shown for the first time to proceed to valeric acid, and the process selectivity is affected by the concentration of surface functionalities
