A series of acidic cesium salts of molybdovanadophosphoric heteropolyacids (CsMVP‐HPAs) are developed as bifunctional and recyclable catalysts for a one‐step approach to 2,5‐diformylfuran (DFF) from fructose with molecular oxygen as the oxidant under environmentally benign conditions. The CsMVP‐HPAs afford the direct synthesis of DFF from fructose through acidic site (H)‐promoted fructose dehydration and metallic site (V)‐catalyzed successive aerobic oxidation of 5‐hydroxymethylfurfural (HMF). The catalytic performances of CsMVP‐HPA toward fructose dehydration and HMF oxidation are related to its acid density and V content, respectively. Moreover, the increase in the V content of CsMVP‐HPA results in its decreased acid density, which suggests its converse catalytic performance toward fructose dehydration and HMF oxidation. An optimum balance between the dehydration and oxidation functions of CsMVP‐HPAs reveals that a ratio of acid density to molar concentration of V between 1.64 and 3.34 achieves a maximum yield of 60 % for DFF from fructose with Cs3HPMo11VO40 as a catalyst under atmospheric pressure of oxygen. Moreover, Cs3HPMo11VO40 behaves as a heterogeneous catalyst and can be easily reused at least for four times. This research highlights an efficient bifunctional catalyst for transforming renewables into fine chemicals in tandem reactions of dehydration and oxidation.

“…These molecules are an assemblage of oxo-bridged early transition metals (mostly Mo, W, and V) in their highest oxidation state [13,14]. Their chemical and physical properties can be tuned, giving rise to a large number of possible applications in the fields of catalysis [15][16][17], material science [18][19][20] and medicine [21][22][23][24]. Moreover, the removal of one or more of the addenda atoms from the POM framework results in the formation of a lacunary species, which can coordinate different metal ions, resulting in the formation of metal-substituted POMs [11,25].…”

A carbonized cassava dregs-supported ruthenium nanoparticles catalyst (Ru/CCD) was prepared by a simple impregnation-chemical reduction method. The synthesized Ru/CCD catalysts were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performances of the Ru/CCD catalysts were evaluated in the conversion of D-glucose into D-sorbitol under hydrogen atmosphere. Moreover, the effects of various parameters on glucose hydrogenation and the recyclability of the catalysts were investigated in detail. The optimized D-sorbitol yield reached up to 98.6% at 120 °C for 1.5 h with D-glucose conversion of 99.7%. The Ru nanoparticles played an important role in the hydrogenation of D-glucose into D-sorbitol, and the Ru particle was widely dispersed all over the support surface. In addition, the Ru/CCD catalyst was stable during the reaction and was reused for up to five successive runs with a slight decrease in D-sorbitol yield.

Biomass, a sustainable resource for the energy and carbon cycles in nature, has aroused worldwide attention (Kobayashi et al. 2011;Han and Lee 2012;Liao et al. 2014;Zhu et al. 2014). Cassava dregs, a waste byproduct with a large lignocellulosic component, are generated during the cassava-based bioethanol production (He et al. 2014;Kristensen et al. 2014;Nguyen et al. 2014). DSorbitol is an important chemical intermediate and a new energy chemical that has significant applications in food, medicine, textiles, and cosmetics, as well as in the chemical industry (Deng et al. 2010;Zheng et al. 2010;Liu et al. 2011;Chen et al. 2013;Negoi et al. 2014;Ribeiro et al. 2017).Recently, D-sorbitol has been produced by catalytic hydrogenation of D-glucose in industrial production. A Raney-type Ni catalyst has been developed for the production of D-sorbitol. However, the Ni in the Raney-type Ni catalyst easily leaches into the solution . In addition, the easy deactivation of the catalyst is an important issue with Raney-type Ni catalysts (Dabbawala et al. 2016). To overcome the drawbacks of the Raney-type Ni catalysts, several catalysts have been applied in the hydrogenation of Dglucose, especially Ru-based catalysts (Mishra et al. 2014;Lazaridis et al. 2015). The Rubased catalysts have higher activity than Raney-type Ni catalysts. Furthermore, the Ru-PEER-REVIEWED ARTICLE bioresources.com Li et al. (2018).
