Making bio-oil from agricultural waste is a promising way to improve the agricultural value chain. Here, furfural (FF), a model bio-oil compound, was subjected to electrocatalytic hydrogenation (ECH) in an alkaline medium to produce economically important furfuryl alcohol (FA) and hydrofuroin (HF). The selectivity of ECH products (FA, HF) on Cu, Pt, and Ni foam electrocatalysts showed that their generation depends on the availability of Hads, which in turn varies with the choice of electrocatalyst and the applied potentials. Cu-NPNi / NF was obtained by de-alloying Cu from a co-electrodeposited Ni-Cu electrode on a Ni foam substrate, followed by renewed electrodeposition of Cu. A porous bimetal Ni-Cu catalyst with a large surface area (Cu-NPNi / NF) on Ni foam resulted in the high rates for FA and HF production from furfural, e.g. B. 118.7 ± 8 and 176.3 ± 3.4 µmol h – 1 cm – 2 at -1.45 V against Ag / AgCl / sat KCl after 1 hour of electrolysis in an alkaline electrolyte. 100% conversion of furfural was observed after 2 hours of electrolysis with the same catalyst. The high rate of FA and HF formation was attributed to an increased adsorbed FF due to the formation of Cu nanoplates as well as bimetal Ni-Cu. We have provided a rational high throughput design for the production of highly active nanoporous electrodes for the production of industrially relevant chemicals (furfuryl alcohol, hydrofuroine).
