La/Ni dual-doping in carbon nanofiber-supported cobalt electrocatalysts toward high-efficiency biomass upgrading

Electrocatalytic oxidation of low-cost 5-hydroxymethylfurfural (HMF) into value-added chemicals like 2,5-furandicarboxylic acid (FDCA) is imperative for sustainable energy and environmental applications. Herein, La/Ni co-doped Co nanoparticles supported on carbon nanofibers (denoted as La,Ni-Co@CNF) demonstrate exceptional electrocatalytic performance for HMF oxidation reaction (HMFOR) with 97.8% FDCA selectivity and 98.2% faradaic efficiency (FE).
