In this paper, MIL‐101(Cr) metal‐organic framework (MOF) has been rapidly synthesized via microwave heating and fully characterized using powder X‐ray diffraction (PXRD), field emission scanning electronic microscopy (FESEM), Fourier transform infrared (FT‐IR) and nitrogen adsorption/desorption isotherm. FESEM image of MIL‐101(Cr) MOF displays spherical particles with a uniform morphology and particle size under 100 nm. The BET surface area and average pore diameter of synthesized MIL‐101(Cr) MOF were obtained to be 7.266 × 102 m2 g−1 and 3.28 nm, respectively. Nickel hydroxide dispersed onto MIL‐101(Cr) nanoparticles modified carbon paste electrode (Ni(OH)2‐MIL/CPE) was employed for electro‐catalytic oxidation of formaldehyde (CH2O) in the alkaline medium. The mean value of electron‐transfer coefficient, charge‐transfer rate constant and surface coverage of the Ni(OH)2‐MIL/CPE are found to be 0.517, 0.0058 s−1 and 7.88 × 10−8 mol cm−2, respectively. Also, the mean value of catalytic rate constant and diffusion coefficient of CH2O in the modified electrode surface are calculated to be 2.37 × 102 cm3 mol−1 s−1 and 1.288 × 10−6 cm2 s−1, respectively. The results indicate that Ni(OH)2‐MIL/CPE displays good electrocatalytic activity to the CH2O oxidation owing to porous structure and the large surface area of MIL‐101(Cr) MOF.

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...

“…Recently, there have been numerous studies of anode materials, including LiTi 2 O 4 , Li 2 Ti 3 O 7 , Li 2 Ti 6 O 13 , Li 4 Ti 5 O 12 , Na 2 Li 2 Ti 6 O 14 , TiNb 2 O 7 , and Li 2 ZnTi 3 O 8 (Tang et al, 2014a ; Chen B.

Li 2 ZnTi 3 O 8 with the cubic spinel structure has been considered as a promising material because of its lack of toxicity, low cost, relatively high theoretical capacity of 227 mA h g −1 , and its low discharge voltage plateau of ~0.5 V (vs. Li/Li + ) (Jović et al, 2009 ; Chen B.

Li2ZnTi2.9Cr0.1O8 and Li2ZnTi3O8 were synthesized by the liquid phase method and then studied comparatively using X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), galvanostatic charge–discharge testing, cyclic stability testing, rate performance testing, and electrochemical impedance spectroscopy (EIS). The results showed that Cr-doped Li2ZnTi3O8 exhibited much improved cycle performance and rate performance compared with Li2ZnTi3O8. Li2ZnTi2.9Cr0.1O8 exhibited a discharge ability of 156.7 and 107.5 mA h g−1 at current densities of 2 and 5 A g−1, respectively. In addition, even at a current density of 1 A g−1, a reversible capacity of 162.2 mA h g−1 was maintained after 200 cycles. The improved electrochemical properties of Li2ZnTi2.9Cr0.1O8 are due to its increased electrical conductivity.
