In the article "Vacancy Mediated Electrooxidation of 5-Hydroxymethyl Furfuryl Using Defect Engineered Layered Double Hydroxide Electrocatalysts," Nicholas M. Bedford and his colleagues discuss a method for improving the selective electrooxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA), which is a sustainable monomer for bioplastics. They demonstrate a Ce-doping strategy that enhances the electrooxidation process. The researchers used in-situ synchrotron methods, structure modeling, and density functional theory calculations to understand the modulated active sites that contribute to the success of the catalyst. This study provides valuable insights for future catalyst design in the field of biomass electrooxidation.
