The catalyst was characterized by Fourier transform infrared (FTIR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) analyses. Superior catalytic activity was shown by the catalyst toward one-pot synthesis of DFF using molecular oxygen as the sole oxidant. The catalyst was found to be highly selective in synthesis of 2,5-diformylfuran (DFF) from hydroxymethylfurfural (HMF), fructose, and, more importantly, from glucose with excellent yields. Moreover, the catalyst was easily recycled and reused without any significant loss in its catalytic activity.1 aRathod, P., V.1 aNale, S., D.1 aJadhav, V., H.  uhttps://library.ncl.res.in/content/metal-free-acid-base-catalyst-selective-synthesis-25-diformylfuran-hydroxynnethylfurfural
