The electrocatalytic hydrogenation (ECH) of biomass-derived levulinic acid (LA) is a promising strategy to synthetize fine chemicals under ambient conditions by replacing the thermocatalytic hydrogenation at high temperature and high pressure. Herein, various metallic electrodes were investigated in the ECH of LA in a H-type divided cell. The effects of potential, electrolyte concentration, reactant concentration, and temperature on catalytic performance and Faradaic efficiency were systematically explored. The high conversion of LA (93%) and excellent “apparent” selectivity to valeric acid (VA) (94%) with a Faradaic efficiency of 46% can be achieved over a metallic lead electrode in 0.5 M H2SO4 electrolyte containing 0.2 M LA at an applied voltage of −1.8 V (vs. Ag/AgCl) for 4 h. The combination of adsorbed LA and adsorbed hydrogen (Hads) on the surface of the metallic lead electrode is key to the formation of VA. Interestingly, the reaction performance did not change significantly after eight cycles, while the surface of the metallic lead cathode became rough, which may expose more active sites for the ECH of LA to VA. However, there was some degree of corrosion for the metallic lead cathode in this strong acid environment. Therefore, it is necessary to improve the leaching-resistance of the cathode for the ECH of LA in future research.

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

Valeric acid and valeric biofuels are obtained in high yield by direct hydrogenation of levulinic acid catalyzed by Pt/HMFI under relatively mild conditions (2 or 8 bar H2, 200 °C), driven by cooperation of the metal and support Brønsted acid sites.
