Figure 5. (A) The selective oxidation of HMF on different catalysts. Kinetic experiments of the oxidation of (B) HMF, (C) DFF and (D) FFCA over Co@CNTs and Co SAs/NPs@N-CNTs. HMF: 5-hydroxymethylfurfural; DFF: 2,5-diformylfuran; FFCA: 5-formyl-2-furancarboxylic acid; CNTs: carbon nanotubes; SAs: single atoms; NPs: nanoparticles.
