“…The results obtained here are completely in line with those reported in the literature with other Au/ZrO 2 catalysts [9,11,13,24]. More recently Au/UiO-66 [6] and Au/CMK-3 [4] catalysts, also showed comparable activity in similar conditions, particularly involving less than 1 wt% Au/furfural and most of the time in the absence of base.…”

“…In the case of furfural, early works reported for example the use of V 2 O 5 -H 2 O 2 systems giving selective formation of methyl-2-furoate at mild temperature [1]. While examples with Co, Pd, Mn nanoparticles supported on carbon have been reported for the oxidative esterification of furfural and 5hydromethylfurfural with O 2 , [2] Au nanoparticles have been mainly used for this reaction [3][4][5][6]. Following reports from Christensen and co. on alcohols [7] and aldehydes [8] esterification with Au/TiO 2 , Signoretto and Manzoli and co. have been very active in this subject [3,[9][10][11][12][13][14].…”

Au/ZrO 2 catalyst prepared from Au 25 (SG) 18 nanoclusters (SG stands for glutathione) deposited on ZrO 2 has shown to be an efficient system for the oxidative esterification of furfural with methanol. The influence of the supported nanoclusters was studied and showed that partial calcination of the supported nanoclusters at 300 °C was sufficient for a quantitative formation of methyl-2-furoate even in the absence of a base. In the presence of 0.27 mol% of Au, initial activities up to 250 h -1 were obtained at 100 °C under 6 bar of O 2 .The reactivity was extended to the oxidative esterification of furfuryl alcohol and the formation of various products and intermediates was discussed.

“…However, although the pristine MOFs own some catalytic abilities, the nanocomposites of MOFs and metal nanoparticles (MNPs) have emerged as sustainable alternatives to the conventional heterogeneous catalysts, wherein MOFs serve as support materials or encapsulation shells . For instance, microporous MOFs can provide a large surface area for loading MNPs working similarly to the mesoporous carbon and silica, where the interactions between the MNPs and the MOFs are very important for preventing the agglomeration of the MNPs in catalysis applications.…”

Freestanding 2D nanosheets with many unprecedented properties have been used in a myriad of applications. In this work, 2D copper-bearing metalorganic frameworks (MOFs; viz., Cu-BDC) nanosheets are successfully fabricated via a facile and benign methodology through using Cu 2 O nanocubes (≈60 nm) as a confined metal ion source and 1,4-benzenedicarboxylic acid (H 2 BDC) as an organic linker. The Cu 2 O nanocubes gradually release Cu + ions which are further oxidized by the dissolved oxygen and serve as nutrients for construction of 2D frameworks. In contrast, the conventional solvothermal synthesis with copper salt exclusively yields bulk Cu-BDC with edge dimensions of 2-10 µm. Interestingly, the as-prepared Cu-BDC nanosheets show ultrathin thickness, oriented growth, and excellent crystallinity, which can be exploited as a platform for the design of a series of 2D-integrated nanocatalysts by loading various metal nanocrystals such as Au, Ag, Pt, and Ru, with 3-mercaptopropionic acid as molecular link. In addition, it is found that Cu-BDC/M composites with highly accessible active sites on the surface exhibit high catalytic activity in several condensation reactions between benzaldehyde and primary amines. The findings offer an alternative strategy for rational design and synthesis of 2D MOF nanosheets and the derived 2D nanocomposites for catalytic applications.

“…[12] Our group has lately carried out some work to explore the oxidative transformation of furfural over Au NPs supported functionalized UiO-66-X (X=NH 2 , COOH, NO 2 ) and some good results has been obtained. [13] In this work, we used the secondary component (Fe or Ni) to decorate the noble metal Pt and MOFs as supporter to fabricate PtÀ Fe/UiO-66 and Pt-Ni 3 /UiO-6 catalysts. The SH of cinnamaldehyde (CAL) containing both C=C and C=O bonds was selected as a typical model reaction for investigation the performance of the PtÀ Fe(Ni 3 )/UiO-66 bi-component structure with the desire to control chemoselectivity.…”

Noble‐metal catalysts serve as an irreplaceable role in pharmaceutical, perfume and fine chemicals fields. However, there still remains a grand challenge in controlling chemoselectivity. Herein, we have synthesized a bimetallic nanostructure supported on porous metal‐organic frameworks (Pt−Fe/UiO‐66, Pt‐Ni3/UiO‐66), in which Pt nanoparticles was modified with non‐noble metal (Fe or Ni) directly. The as‐synthesized catalysts can function as a switch for selective hydrogenation of α,β‐unsaturated aldehydes to afford the potential products on‐demand. In comparison with the conventional Pt‐based catalysts, Pt−Fe/UiO‐66 and Pt‐Ni3/UiO‐66 catalysts exhibit excellently catalytic activity, enhanced selectivity and improved stability for selectivity hydrogenation. The partial charge reconfiguration and electronic coupling effect existing in such distinctive bicomponent nanocatalysts was confirmed by some comprehensive characterization and density functional theory (DFT) calculations. The developed method for precisely modification the composition and interaction between the noble metal and non‐noble metal provides a feasible avenue to design the advanced catalysts.
