“…The concentration of negative charge of the adsorbent increases with increasing pH of the MB solution, which is beneficial for improving the adsorption capacity because of electrostatic interaction. Interestingly, the adsorption amount increases with decreasing pH value (2–7), which is different from previous reports . The concentration of positive charge increases with decreasing pH, meaning that electrostatic interaction is no longer working because of charge repulsion between the surface of GO/MOFs and MB.…”

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

Although metal‐organic frameworks have proven to be excellent electrocatalytic materials, their application as electrode materials remains limited. The preparation of heterostructures is considered an effective method to improve catalytic activity. Herein, we describe the design and assembly of a dual‐MOF heterostructure (CoNi−ZIF‐67@Fe−MIL‐100, denoted ZIF@MIL). Specifically, we grew a layer of MIL‐100 in situ on a bimetallic ZIF‐67 surface using a solvothermal method. We demonstrate that the ZIF@MIL has remarkable OER electrocatalytic performance, requiring a low overpotential and showing a small Tafel slope, compared to pure ZIF‐67 and MIL‐100 in 1.0 m KOH. More importantly, it has excellent operational durability for 50 h at 100 mA cm−2. The high catalytic activity of ZIF@MIL can be attributed to the heterostructure that can expose more active sites, the synergistic effect between ZIF‐67 and MIL‐100, and improvement of electron transfer ability. Our work provides a new way to design and prepare dual‐MOF crystals with different structures as electrocatalysts.

Developing an effective adsorbent for olefin/paraffin separation is a crucial and challenging issue. We have developed an olefin‐selective adsorbent by loading two different Cu(II) salts (CuCl2 and Cu(CH3COO)2) within an iron‐based metal–organic framework (MOF) and reduced them to Cu(I) species without a high‐temperature calcination and an external reducing agent. The successful development of Cu(I)‐loaded MOFs was confirmed by characterizations including scanning electron microscope/energy dispersive X‐ray spectroscopy, X‐ray photoelectron spectroscopy, powder X‐ray diffraction, and Brunauer–Emmett–Teller analyses. From the comparisons between Cu(I)‐loaded MOFs degassed at two different temperatures, we confirmed that the unsaturated Fe(II) sites within the iron‐based MOF can enhance the stability of formed Cu(I) species and thus improve the C3H6/C3H8 selectivity. The resulted Cu(I)‐loaded MOF shows large C3H6 uptake (5.15 mmol/g) and high C3H6/C3H8 selectivity (8.9) at 100 kPa and 293 K.
