Biomass-derived 5-hydroxymethylfurfural (HMF) electrooxidation to 2,5-furandicarboxylic acid (FDCA) offers great potential for sustainable chemical production, yet voltage-efficient selective direct oxidation remains challenging. Herein, a Pt/TiO2 catalyst characterized by dense Pt-O-Ti interfaces is presented, demonstrating an impressive FDCA selectivity of 97.3% at a low potential of 0.8 V (vs. reversible hydrogen electrode) during the alkaline oxidation of HMF, outperforming Pt/C, which shows only 62.7% selectivity. Additionally, the Pt/TiO2 catalyst exhibits high CO resistance and remains stable for more than 200 h during HMF oxidation. Experimental data and density functional theory calculations indicate that the enhanced performance originates from strong Pt-O-Ti interfacial electron coupling, which accelerates the rate-determining step of 5-hydroxymethyl-2-furanocarboxylic acid oxidation by promoting hydroxyl (OH*) formation and reducing C-H bond activation energy. These results provide crucial insights into the mechanisms of the interface effect relevant to direct biomass electrooxidation at low voltages.

In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...
Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
