Low-voltage, membrane-free electrolysis produces hydrogen and FDCA

A new approach to the traditional alkaline electrolyzers used to produce “green” hydrogen from water eliminates the membrane and introduces a new reaction mechanism at the anode, enabling the production of a high-value plastic precursor, 2,5-furandicarboxylic acid (FDCA). Developed at Keele University, the new electrolyzer facilitates two different chemical reactions — the conventional conversion of water into hydrogen at the cathode; and the electrosynthesis of 5-hydroxymethylfurfural (HMF) into FDCA at the anode.
