Metal-organic frameworks (MOFs), a new class of crystalline porous materials, can be applied in many fields as adsorbents, supercapacitors, catalysts, and so on because of, among others, their superior properties of large surface area, tunable pore size, diverse structures. However, the low stability and selectivity of traditional MOFs indicate that they are not the best configuration for the applications outlined above. In this case, a type of composite made from an assembly of graphene-based materials and MOFs that exhibits the advantages of the parent materials has attracted widespread attention in recent years. This review provides an overview of the recent developments of MOF/graphene-based materials, focusing on their applications in gas separation/storage, water purification, chemical sensors, batteries, supercapacitors, and catalysts, as well as their preparation methods.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201804950. traditional method, they can be excellent alternatives of single MOFs to overcome the above-mentioned difficulties. [34][35][36][37][38] Graphene-based materials have recently introduced new possible applications because of their unique structure and low toxicity, as well as their excellent electronic, thermal, electrochemical, and mechanical properties. [39] More recently, many reports have confirmed that the introduction of graphene-based materials into other materials can lead to surprising improvements in electronic conductivity and stability. [38,40] Under these circumstances, it is reasonable to consider whether composites made from the assembly of graphene-based materials and MOFs possess extraordinary characteristics given that the parent materials have complementary properties. [40][41][42] Naturally, the idea of hybridizing graphene derivatives with MOFs materialized and soon attracted widespread attention. [43][44][45] According to recent research, composites of MOF/graphene-based materials can integrate the advantages and mitigate the shortcomings of the individual components perfectly, enabling the composites to possess improved stability, enhanced electrical conductivity, high selectivity, and template effects. [34,[46][47][48][49] With the combination of MOF and graphene-based materials, the unexpected interactions take place and bring unique performance in many applications. Thanks to the ionic groups and the aromatic sp 2 domains, graphene-based materials can not only function as structural nodes, but also participate in bonding interactions, which would be more active in MOFs. What's more, carboxylate and pyridine groups of graphene-based materials play important part in the assemble, which could enhance the coordination bonding and guide the growth of MOF, providing a more beneficial structure. These special interactions are unique in MOF/graphenebased materials, which indicates that this kind of materials deserve more attention. As concluded in Scheme 1, the addition of graphene-based material...

“…Thereby, dye wastewater should be decolorized well before further treatment or application. In this instance, the decolorization of dye wastewater has been a giant challenge to scientists and engineers . Advanced oxidation technologies (AOTs) including Fenton, photocatalytic and electrochemical methods, and so on, which rely on in situ produced reactive oxygen species, such as hydroxyl radical to dispose colored, toxic, and stable organic pollutants, have been employed to decolorize dye wastewater.…”

A very distinctive modification route was schemed to fabricate a membrane reactor that could heterogeneously catalyze Fenton reactions to decolorize dye wastewater in the process of filtration. Through this route, porogen-free polyacrylonitrile (PAN) hollow fiber membrane was decorated with in situ generated well-distributed Fe/Mn composite oxide, and the so-called membrane reactor was finally acquired. Its performance of decolorizing dye wastewater was evaluated by feeding methylene blue (MB) aqueous solution into its lumen side and analyzing the permeate gained from its shell side. The results showed that about 97.4% of MB could be removed from its aqueous solution as the solution passed through the shell side of hollow fiber membrane, and this removal efficiency would keep unchanged when operation period was lengthened. The membrane reactor presented excellent capability to decolorize MB aqueous solution and could be used repeatedly without any loss in decolorization efficiency. Finally, the mechanism of causing MB decolorization was proposed by comparing decolorization performance of modified and unmodified membranes, measuring total organic carbon, and analyzing UV-Vis spectra.

In this research, a novel magnetic mesoporous adsorbent with mixed phase of Fe2O3/Mn3O4 nanocomposite was prepared by a facile precipitating method and characterized extensively. The prepared nanocomposite was used as adsorbent for toxic methyl orange (MO) dye removal from aqua matrix considering its high surface area (178.27 m2/g) with high saturation magnetization (23.07 emu/g). Maximum dye adsorption occurs at solution pH 2.0 and the electrostatic attraction between anionic form of MO dye molecules and the positively charged nanocomposite surface is the main driving force behind this adsorption. Response surface methodology (RSM) was used for optimizing the process variables and maximum MO removal of 97.67% is obtained at optimum experimental condition with contact time, adsorbent dose and initial MO dye concentration of 45 min, 0.87 g/l and 116 mg/l, respectively. Artificial neural network (ANN) model with optimum topology of 3–5–1 was developed for predicting the MO removal (%), which has shown higher predictive ability than RSM model. Maximum adsorption capacity of this nanocomposite was found to be 322.58 mg/g from Langmuir isotherm model. Kinetic studies reveal the applicability of second‐order kinetic model with contribution of intra‐particle diffusion in this process.
