“…50 Furthermore, the Congo red adsorption capacities of other metal oxides range from 1204 to 2409 mg g À1 , which is ascribed to their chemical composition and microstructure. [51][52][53] Among these adsorbents, both hydrophobic and hydrophilic adsorption contribute to the adsorption of Congo red. Adsorption capacities of the prepared gemini surfactant/GO composites in this study are signicantly higher than those of most adsorbents, and their fast adsorption rate also shows great superiority.…”

“…Several adsorbents such as activated carbon, molecular sieve, clay and zeolite have been applied to the adsorption of dyes from contaminated water. Recently, metal–organic frameworks (MOFs) have attracted increasing attention for the removal of dyes from wastewater . Metal–organic frameworks, as a new class of crystalline porous materials, have received more and more attention from the scientific community because of their high porosity, large surface area and tunable pore size .…”

“…39 The use of MIL-68 (Zn) for the removal of Congo red (CR) from wastewater has also been reported. 27 However, it should be pointed out that the open framework of MOFs is not able to provide strong adsorption forces to retain small molecules under ambient condition. 40 In addition, some MOFs show poor stability in humid conditions.…”

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

Photocatalytic water splitting coupled with the production of highly value-added organic chemicals is of significant importance, which represents a very promising pathway for transforming green solar energy into chemical energy. Herein, we report a composite photocatalyst CdIn 2 S 4 @MIL-53-SO 3 Ni 1/2 , which is highly efficient on prompting water splitting for the production of H 2 in the reduction half-reaction and selective oxidation of organic molecules for the production of highly value-added organic chemicals in the oxidation half-reaction under visible light irradiation. The superior photocatalytic properties of the composite photocatalyst CdIn 2 S 4 @MIL-53-SO 3 Ni 1/2 should be ascribed to coating suspended ion catalyst (SIC), consisting of redox-active Ni II ions in the anionic pores of coordination network MIL-53-SO 3 À , on the surface of photoactive CdIn 2 S 4 , which endows photogenerated electron-hole pairs separate more efficiently for high rate production of H 2 and selective production of highly value-added organic products, demonstrating great potential for practical applications.
