Much attention has been paid to metal-organic frameworks (MOFs) due to their large surface areas, tunable functionality, and diverse structure. Nevertheless, most reported MOFs show poor hydrothermal stability, which seriously hinders their applications. Here a strategy is adopted to tailor the properties of MOFs by means of incorporating carboxyl-functionalized natural clay attapulgite (ATP) into HKUST-1, a well-known MOF. A new type of hybrid material was thus fabricated from the hybridization of HKUST-1 and ATP. Our results indicated that the hydrothermal stability of the MOFs as well as the catalytic performance was apparently improved. The frameworks of HKUST-1 were severely destroyed after hydrothermal treatment (hot water vapor, 60 °C), while that of the hybrid materials was maintained. For the hybrid materials containing 8.4 wt % of ATP, the surface area reached 1302 m(2)·g(-1) and was even higher than that of pristine HKUST-1 (1245 m(2)·g(-1)). In the ring-opening of styrene oxide, the conversion reached 98.9% at only 20 min under catalysis from the hybrid material, which was obviously higher than that over pristine HKUST-1 (80.9%). Moreover, the hybrid materials showed excellent reusability and the catalytic activity was recoverable without loss after six cycles. Our materials provide promising candidates for heterogeneous catalysis owing to the good catalytic activity and reusability.

“…40,[46][47][48] MOF/GO composites can combine the advantages of MOFs and the dense graphene layers of GO. In fact, In-MOF/GO, HKUST-1/GO, Fe 3 O 4 /HKUST-1/GO and MOF-199/GO 26,44,49,50 have been reported in the removal of organic pollutants. On the basis of the above analysis, MOF/GO composites can be expected to be effective adsorbents for the removal of dye from aqueous solution.…”

BACKGROUND Dye wastewater is causing a serious problem to the environment and to human health. A considerable amount of colored wastewater is generated from many industries. Moreover, many dyes in the wastewater are believed to be toxic and even carcinogenic. Therefore, the removal of dyes from wastewater is necessary and urgent. RESULTS The adsorption kinetics, isotherms and intra‐particle diffusion model were determined from experimental data, and the results indicated that the pseudo‐second‐order kinetic model and the Langmuir adsorption isotherm matched well the adsorption of MB onto GO/MOFs. Thermodynamic parameters revealed that the adsorption of MB by GO/MOFs was spontaneous and exothermic. The adsorption capacity was greatly improved in acidic or alkaline aqueous solution. The maximum adsorption capacity of GO/MOFs reached 274 mg g‐1, higher than most previously reported adsorbents. Also, the adsorbent could be used at least five times after washing with ethanol. CONCLUSION A microwave‐assisted ball milling method was used successfully to synthesize Ni‐MOFs and GO/MOFs. Because of electrostatic interaction and acid–base interaction, both acidic and alkaline aqueous solutions were found to favor the adsorption of MB by GO/MOFs, this being different from previous reports. GO/MOFs also showed acceptable reusability after being regenerated by ethanol. All the results suggest that MOFs prepared by microwave‐assisted ball milling give the prospect of removal of MB from aqueous solution. © 2017 Society of Chemical Industry

“…MOF composites are multifunctional materials composed of MOFs and other distinct constituent materials, including quantum dots [5,6], metal nanoparticles [7][8][9], graphene [10][11][12][13], MWCNTs [14], porous silica nanospheres [15], and magnetic beads [16]. In particular, owing to the merit of unique magnetic properties, the combinations of magnetic materials with MOFs have sparked great excitement especially in drug delivery [17,18], catalysis [19], adsorption [20,21] and detection [22,23].…”
