Ammonia Etching to Generate Oxygen Vacancies on CuMn₂O₄ for Highly Efficient Electrocatalytic Oxidation of 5-Hydroxymethylfurfural

Electrocatalytic biomass valorization with renewable energy input represents a promising way to produce sustainable and non-fossil-based carbon products. The oxidative production of furandicarboxylic acid (FDCA) from bio-based 5-hydroxymethylfurfural (HMF) has attracted one of the most attention. Herein, spinel CuMn2O4 with an urchin-like nanostructure was synthesized by a hydrothermal method and subsequently soaked in ammonia water to create...
