The electrode preparation requirements investigated by INSTM were outlined, and the resulting electrode meets the standards for industrial applications while demonstrating the characteristics of a dimensionally stable anode (DSA) with excellent conductivity and corrosion resistance.

To create the electrode, a thermal deposition process was employed, which involved applying a mixed SnO2-Sb2O3 oxide underlayer onto a titanium mesh substrate. Subsequently, the PbO2 active phase was electroplated onto the modified Ti mesh. Utilizing the prepared anode, maleic acid (MA) can be efficiently generated from furfural (FF), achieving high values (>90%) for the total Faraday Yield (maleic acid + HFO) attained.

These results generate an important milestone within the PERFORM project research, which aims to develop efficient and integrated electrochemical systems which substantially improve oxidative chemical transformations based on bio-based feedstocks.
