“…Compared with the production of DFF from HMF,t he direct one-pot conversion of monosaccharides (fructosea nd glucose) into DFF with high yield is desirable and still ag reat challenge, [22,41,42] which involves the selectivedehydration of carbohydratesi nto HMF over acid sites and the consequent oxidation of HMF to DFF over redox sites. [22] However,p roduction of DFF has often been obtained in one pot and two steps, including the acidification and oxidation reaction, whichf aces a major drawback in the formation of humins and other undesired byproducts owing to the coexistence of acid and redox sites.…”

“…[94] The HRTEM image of Pd@UiO-66/SGO (4.8 % Pd loading) showed a uniform distribution of Pd NPs with a mean size of 3.5 � 0.5 nm on the particles of UiO-66. In one of these less-abundant examples, Pd was loaded on UiO-66 by impregnation and the particles deposited on sulfonated graphene oxide (Pd@UiO-66/SGO) (SGO stands for sulfonated graphene oxide).…”

frameworks (MOFs) are currently attracting considerable attention as heterogeneous catalysts at moderate temperatures, mainly for liquid-phase reactions. Since structural stability is one of the major concerns for the use of MOFs in catalysis, particularly considering that frequently some of the reported MOF materials are very unstable, the interest in this area has been focused on those MOFs exhibiting the highest structural robustness, UiO-66 being among the most widely used. Two introductory sections deal with the synthesis, structure and main properties of UiO-66, including its remarkable thermal (up to 350°C) and chemical (aqueous solution in a wide pH range) stability. The main body of the review summarizes those examples of using UiO-66 in catalysis grouped according to the nature of the active sites, starting with the use of UiO-66 as Lewis acids. In this section, emphasis has been made in the recent strategies to create structural defects in a controlled way that generate Lewis acidity. Other sections cover examples illustrating substituted terephthalate as active sites and the evidence that there is a synergy between acid and basic sites in close proximity that make some of these UiO-66 with substituents at the linker to act as dual acid-base catalysts. Other sections are focused on the use of UiO-66 as hosts of metal nanoparticles, metal oxides and other host, remarking the influence that the nature of UiO-66 and the possible presence of substituents in the framework play on the activity of the incorporated guest. The last section summarizes the current state of the art in the use of UiO-66 in catalysis and provides our views on future developments regarding the application of UiO-66 in industrial processes.

“…[50] In addition, the hydrophilic surface and Brønsted acid of GO can enhance the fructose adsorption onto the surface of the catalysts. [51] In recent years, many research teams reported that the GO has been utilized as a heterogeneous catalyst for various acid-catalyzed reactions, such as hydrolysis of cellulose glucose and fructose. [52][53][54] Therefore, the graft of MOFs on GO support may intend to solve the agglomeration problem and achieve high-efficiency catalytic conversion of glucose to 5-HMF.…”

Developing a supported‐type metal–organic frameworks (MOFs) catalyst with multifunctional active sites is essential to broaden its application as a heterogeneous catalyst. Herein, polydopamine (PDA)‐modified graphene oxide (PDA@GO) is used as a support to prepare an acid–base bifunctional UiO‐66‐type MOFs catalyst in green solution (aqueous solution) through a one‐pot method. By adjusting the amount between GO, PDA, UiO‐66‐NH2, and UiO‐66‐SO3H, the heterogeneous solid catalyst UiO‐66‐SO3H‐NH2/PDA@GO with uniform distribution of MOFs can be obtained. The morphology and various properties of the catalyst are characterized and the catalytic performance of the catalyst for the conversion of glucose to 5‐hydroxymethylfurfural (5‐HMF) is demonstrated and discussed. Herein, the supported‐type MOFs catalyst offers an alternative way to promote current acid–base catalytic systems for achieving efficient production of 5‐HMF from sustainable biomass.

Direct one-pot conversion of monosaccharides into high-yield 2,5-dimethylfuran over a multifunctional Pd/Zr-based metal–organic framework@sulfonated graphene oxide catalyst

Abstract: A one-pot conversion of monosaccharides (fructose and glucose) into high-yield 2,5-dimethylfuran (2,5-DMF) is demonstrated over a multifunctional catalyst obtained by loading Pd on UiO-66@ sulfonated GO (Pd/UiO-66@SGO).
