“…Al arge number of literatures have reported non-noble metal alloy electrocatalysts with doping of nitrogen species for ORR, [16][17][18][19][20][21] but the pure alloy electrocatalysts withoutn itrogen doping is rarely reported. In this work, the carbon-coated Cu-Fe alloy (FeCu@C) without and with nitrogend oping was prepared by using Cu/Fe-MOF-74 as as elf-sacrificing template (Scheme 1).…”

Well-dispersed carbon-coated or nitrogen-doped carbon-coated copper-iron alloy nanoparticles (FeCu@Co r FeCu@CÀN) in carbon-based supports are obtained using a bimetallic metal-organic framework (Cu/Fe-MOF-74)o ra mixture of Cu/Fe-MOF-74 and melamine as sacrificial templates and an active-component precursor by using apyrolysis method.T he investigation resultsa ttest formation of CuÀ Fe alloy nanoparticles. The obtained FeCu@Cc atalyst exhibits ac atalytic activity with ah alf-wave potential of 0.83 Vf or oxygen reduction reaction (ORR) in alkalinem edium, comparable to that on commercial Pt/C catalyst (0.84 V).T he cata-lytic activity of FeCu@CÀNf or ORR (E half-wave = 0.87 V) outshinesa ll reported analogues. The excellent performance of FeCu@CÀNs hould be attributedt oachange in the energy of the d-band center of Cu resulting from the formationo f the copper-iron alloy,t he interaction between alloy nanoparticlesa nd supports and N-dopingi nt he carbon matrix. Moreover,F eCu@C and FeCu@CÀNs how better electrochemicals tability and methanol tolerance than commercial Pt/C and are expected to be widely used in practical applications.

“…In modern life, energy issues are one of the most serious problems shared by all countries, so it is necessary to spare no efforts to address the issue of energy storage . In regard to batteries, lithium‐ion batteries (LIBs) and sodium‐ion batteries (SIBs) have attracted the most attention because of their high energy density, long cycle life and light weight.…”

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...

“…Previously, a hierarchical ower-like Ni-MOF [Ni 3 (OH) 2 (PTA) 2 (H 2 -O) 4 ]$2H 2 O (PTA ¼ p-benzenedicarboxylic acid) was prepared by the hydrothermal reaction between Ni 2+ and PTA at 150 C. The resulting Ni-MOF showed high electrocatalytic activity and good stability for glucose oxidation reaction. 30 In addition, hierarchical ZIF nest architectures were previously synthesized by the solvothermal reaction of zinc nitrate hexahydrate with 2-ethylimidazole and 5,6-dimethylbenzimidazole in a mixed solvent of methanol and aqueous ammonia. 31 Despite these achievements, it is still challenging to develop a generalized route for fabricating hierarchical 3D MOFs assembled from 2D nanostructures, such as nanosheets/nanoplates.…”
