Clean H₂ Production by Lignin-Assisted Electrolysis in a Polymer Electrolyte Membrane Flow Reactor.

ABSTRACT: Biomass-derived products, such as lignin, are interesting resources for energetic purposes. Lignin is a natural polymer that, when added to the anode of an alkaline exchange membrane water electrolyser, enhances H₂ production rates and efficiencies due to the substitution of the oxygen evolution reaction. Higher efficiencies are reported when different catalytic materials are employed for constructing the lignin anolyte, demonstrating that lower catalytic loadings for the anode improves the H₂ production when compared to higher loadings. Furthermore, when a potential of -1.8 V is applied, higher gains are obtained than when -2.3 V is applied. An increase of 200% of H₂ flow rates with respect to water electrolysis is reported when commercial lignin is used c
