“…The CO2 and CH4 adsorption performance of HKUST-1 [22] and MIL-53(Cr) [23] were enhanced through using MWCNT. Similarly, graphene oxide (GrO) has been incorporated into MIL-101(Cr), showing an increase of 44.4% for the adsorption of acetone compared to the neat material [24]. Another composite of MIL-101(Cr) but with GO showed an increase of 25-29% in the n-alkanes adsorption capacity compared to the neat material [25].…”

Adsorption heat pumps can be used for generating heating, cooling, seasonal energy storage and water desalination applications. Metal-organic frameworks (MOFs) are hybrid porous materials with high surface area and superior adsorption characteristics compared to conventional adsorbents. MIL-101(Cr) has a large pore size with water vapour adsorption capacity up to 1.5 gH2O gads -1 and high cyclic stability thus has the potential to be used in adsorption heat pumps. This work investigates the enhancement of the thermal conductivity and water adsorption characteristics of MIL-101(Cr) using hydrophilic graphene oxide. Two methods have been used to develop MIL-101(Cr)/GrO composites. The first method was through physical mixing between MIL-101(Cr) and GrO while the other was through incorporating the GrO during the synthesis process of MIL-101(Cr). The composites and MIL-101(Cr) were characterized in terms of their structure, water adsorption uptake, BET surface area, particle size, thermal gravimetric analysis, SEM images and thermal conductivity measurements. Results showed that introducing low amounts of GrO (<2%) to the neat MIL-101(Cr) enhanced the water adsorption characteristics at high relative pressure but enhanced the heat transfer properties by 20-30% while using more than 2% of GrO reduced the water adsorption uptake but significantly enhanced the thermal conductivity by more than 2.5 times.

“…For example, Bandosz and other groups have prepared several samples of MOF/GO hybrids such as MOF-5/GO [46,47], HKUST-1/GO [48], MIL-100(Fe)/ GO [49], MIL-101(Cr)/GO [50], MOF-199/GO [51], MIL-53(Fe)/GO [52] and ZIF-8/GO [53]. The synergistic effects on porosity and chemistry of such composites result in a significant improvement in the adsorption of various gases (NH 3 , NO 2 , H 2 S, H 2 , CO 2 ) [54e61], solvents (n-hexane [62], acetone [63]) and methylene blue from wastewater [64], compared to the pristine MOFs. In fact, this enhancement can be mainly ascribed to the formation of new pores on the interface between two phases (MOF and GO) and active chemistry participating in reactive adsorption.…”

“…The hybridization of MOFs and PRGO could be a promising approach to further disperse the nanoparticle catalyst and to tune catalyst–support interactions to improve the catalytic activity and possibly control the selectivity to the desired products . As a result of the low density of atoms in the frameworks, MOFs may not provide strong dispersive forces to support metal nanoparticles.…”

Palladium Nanoparticles Supported on a Metal–Organic Framework‐Partially Reduced Graphene Oxide Hybrid for the Catalytic Hydrodeoxygenation of Vanillin as a Model for Biofuel Upgrade Reactions

In this work we report a new strategy to enhance the catalytic activity and selectivity in heterogeneous catalysis by using a hybrid support that consists of metal–organic framework (MOF) crystals and partially reduced graphene oxide (PRGO) nanosheets to disperse metal nanoparticle catalysts efficiently. We report the development of a Pd nanocatalyst incorporated within a 3 D hierarchical nanocomposite that consists of a Ce‐based MOF wrapped with thin PRGO nanosheets, Pd/PRGO/Ce‐MOF, as a heterogeneous tandem catalyst for the hydrodeoxygenation of vanillin, a common component in lignin‐derived bio‐oil, under mild reaction conditions. Our results demonstrate that the PRGO/Ce‐MOF hybrid scaffold is an excellent support for Pd nanoparticles for the transformation of vanillin into 2‐methoxy‐4‐methyl phenol, an important high‐value phenol compound that can be used directly in the chemical and pharmaceutical industries. The high catalytic performance of the Pd/PRGO/Ce‐MOF catalyst is attributed to the unique characteristics of the incorporation of the PRGO support that leads not only to a stable and uniform dispersion of the Pd nanoparticles but also to the presence of acidic active sites that promote the hydrogenolysis reaction.
