“…This explains the signicant effect of the incorporation of MCM-41 during the formation of MOF and the high dispersion of the Cu-Ag MOF inside and outside the pores of MCM-41. 66,68,71 The EDX spectra in Fig. 3(e and f) reveal the contribution of C, O, Cu, Ag, and Si elements in the Cu-Ag MOF/MCM-41 composite structure while C, O, Cu and Ag elements in the Cu-Ag MOF structure.…”

“…The detection limit of the determinations, evaluated on the basis of S/N=3 was found to be 0.2 μmol L −1 for HQ and 0.5 μmol L −1 for CC. It is acceptable, compared with data reported in the literature, which show that the detection limits reached by applying DPV and modified electrodes vary in the range from 0.007 μmol L −1 to 50 μmol L −1 for HQ and from 0.009 μmol L −1 to 50 μmol L −1 for CC . Costly materials and complicated techniques for electrode modification were required to achieve lower limits of detection by DPV.…”

The second order voltammetric technique of high resolution, Differential Alternative Pulses Voltammetry (DAPV), was applied for the simultaneous determination of hydroquinone (HQ) and catechol (CC) on bare spectroscopic graphite electrode. Well resolved anodic and cathodic peaks situated on both sides of the zero line were obtained, while the differential pulse voltammograms were overlapped. The linear concentration range for HQ and CC quantification by DAPV was extended up to 20 μmol L−1 for both the isomers. The sensitivity of the determination was found to be 6.00 μA L μmol−1 and 3.61 μA L μmol−1, while the limit of detection reached was 0.2 μmol L−1 and 0.5 μmol L−1 for HQ and CC, respectively. No interference was observed from the commonly coexisting organic species such as resorcinol, phenol and p‐benzoquinone. The great resolution power of DAPV permitted obtaining excellent results without any electrode modification and any mathematical data processing.

“…Figure e,f shows the DPV curves of catechol (CT) and hydroquinone (HQ) with the addition of the detected matter, which suggested that the oxidation peaks of the two analytes at MOF‐ERGO‐5/GCE were well separated. Furthermore, the concentrations and current responses of CT and HQ demonstrated a good linear relationship, which made the determination more simple …”

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...
