Abstract

Both the rational selection of anodic substrate and the design of integrated electrode are highly significant for the development of hybrid water splitting for hydrogen generation at lower electric energy consumption coupled with value-added anodic product generation. Herein, the bimetallic hydroxide nanowires arrays using nickel foam as the robust substrate (denoted as Cu 2 Co(OH) x /NF ) have been synthesized via a facile, fast and green microwave-assisted heating method. Then Cu 2 Co(OH) x /NF  can be used as an integrated electrode for the electrocatalytic oxidation of cheap furfuryl alcohol, one of the representative biomass platform molecules, to more valuable furoic acid companying with the cathodic fast hydrogen generation at decreased potential in 1.0 M NaOH. The true electro-driven upgradation of biomass is thought to be achieved, because furfuryl alcohol is so stable that it would not spontaneously experience Cannizzaro reaction, which is different from furfural and 5-hydroxymethylfurfural containing formyl group that is highly sensitive to strong base. Using this hybrid water splitting system, a current density of 10 mA cm −2 can be output at the much lower potential than that of the full water splitting.
