“…Due to the curve shapes and also based on some literature research, these WEs were also chosen for further CA experiments. 20,33,46 The difference in the onset potentials with Sn in combination with and without FF was 0.1 V, and for CP, it was nearly 0.2 V. Pt and Cu were not selected for further experiments due to the visually visible HER and the very similar onset potentials. Pt is also known for its very strong HER development, as reported in the literature.…”

“…Furthermore, the use of organic solvents and mediators in many processes is less sustainable compared to aqueous solutions. [30][31][32][33][34] Overall, processes could become more sustainable and environmentally friendly by replacing certain chemicals or solvents. For instance, greener electrolytes like acetic acid or levulinic acid, producible in bioreneries, could be employed.…”

Electrocatalytic hydrogenation of furfural to furfuryl alcohol represents a sustainable approach to utilizing renewable energy for producing bio-based platform chemicals. However, low Faraday efficiencies (FEs) and the use of organic solvents with high environmental impacts often render the process less sustainable than classical catalytic hydrogenation. In this study, a two-compartment and three-electrode setup at ambient temperature and atmospheric pressure, featuring various electrodes (Ag, Au, CP, Cu, Pt, Sn, and a gold-coated silver wire (AucAg)), and biomass-derived electrolytes (acetic acid, levulinic acid, and sodium acetate), was tested. AucAg, serving as an electrocatalyst with 1 M sodium acetate as electrolyte, exhibited the best combination of FE and furfuryl alcohol yield with 82% and 37%, respectively. The optimum conditions were achieved at 100 rpm and −0.8 V vs. RHE. Scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) analyzes indicated no significant influence of the substances on the working electrode during the reaction. Since the identity of the cation of the electrolyte influences the electrode-electrolyte microenvironment, multiple alkali metals were trialed. Sodium ion as the counter ion emerged on top, surpassing potassium, and cesium ions for the electroreduction of furfural to furfuryl alcohol. This preference could be attributed to the competing hydrogen evolution reaction favored by Cs over K and Na. In this perspective, the highlights of a bioelectrorefinery concept for creating a bio-derived platform chemical in a sustainable solvent with green electrons are demonstrated and optimized.
