Recent progress, trends, and new challenges in the electrochemical production of green hydrogen coupled to selective electrooxidation of 5-hydroxymethylfurfural (HMF)

Abstract

An integrated electrochemical system can simultaneously produce H2 and FDCA at a lower energy cost than required for electrolytic water splitting with attractive benefits and applications over other production methods.

Metal–organic frameworks (MOFs) for hybrid water electrolysis: structure–property–performance correlation

“…72,131,132 This process, when coupled with HER, allows for the simultaneous production of H 2 and valuable chemical products, thus reducing electricity consumption. 41,43,45,133 Compared to electrochemical UOR and HzOR, exploiting suitable alcohol oxidation reactions presents a promising approach to achieving this dual objective. 42,46,48…”

“…Specifically, anodic electrooxidation of methanol and ethanol has garnered significant attention for facilitating hybrid water electrolysis. 41,43,45,133 Notably, in the realm of alcohol oxidation reactions, such as methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR), factors like electrolytic solution pH and electrocatalytic properties critically influence reaction pathways and efficiency in converting reactants into desired products. 41,43,45,133 By meticulously controlling and optimizing these parameters, researchers aim to enhance the selectivity and efficiency of alcohol oxidation reactions, enabling the simultaneous production of H 2 and valuable chemical products with minimal energy input.…”
