“…Only 240 mV overpotential is required for t-Co II -Co III to reach the anodic current density of 10 mA cm À2 .Importantly,the water oxidation current density obtained for t-Co II -Co III is far better than the template-free catalyst f-Co II -Co III under similar reaction conditions.Moreover,the templated catalyst outperforms the water oxidation activity of the noble metal catalyst RuO 2 in alkaline medium and many other carbon cloth supported first-row transition-metal catalysts reported previously (Supporting Information, Table S2). [13][14][15][16][17][18][19][20] Scheme 1. As the t-Co II -Co III is transformed into al ayered hydroxide structure during OER (see later), we have compared the activity with reported layered double hydroxide catalysts and better performance of our catalyst is observed (Supporting Information, Table S2).…”

The development of efficient and stable catalyst systems with low-cost, abundant, and non-toxic materials is the primary demand for electrochemical water oxidation. A unique method is reported for the syntheses of metal hydroxide carbonate templated Prussian blue analogues (PBAs) on carbon cloth and their outstanding water oxidation activities in alkaline medium. The best water oxidation activity is obtained with cobalt hydroxide carbonate templated t-Co -Co with an overpotential as low as 240 mV to reach a current density of 10 mA cm . It produces constant current over 50 h in chronoamperometric measurements. Moreover, the catalysts outperform the activities of the PBAs prepared without any template and even the noble metal catalyst RuO . Spectroscopic and microscopic studies show that the PBAs are transformed into layered hydroxide-oxyhydroxide structures during electrochemical process and provide the active sites for the water oxidation.

Improving the performance of anode materials for lithium-ion batteries (LIBs) is ah otly debated topic. Herein, hollow NiÀCo skeleton@MoS 2 /MoO 3 nanocubes (NCM-NCs), with an average size of about1 93 nm, have been synthesized through af acile hydrothermal reaction. Specifically, MoO 3 /MoS 2 composites are grown on NiÀCo skeletons derived from nickel-cobaltP russian blue analogue nanocubes (NiÀCo PBAs). The NiÀCo PBAs were synthesized through a precipitation method and utilized as self-templates that provided al arger specific surface area for the adhesion of MoO 3 /MoS 2 composites. According to Raman spectroscopy results,a s-obtained defect-richM oS 2 is confirmed to be a metallic 1T-phase MoS 2 .F urthermore, the average particle size of NiÀCo PBAs ( % 43 nm) is only about one-tenth of the previously reported particles ize ( % 400 nm). If assessed as anodes of LIBs, the hollow NCM-NC hybrids deliver an excellent rate performance and superiorc ycling performance (with an initial discharge capacity of 1526.3 mAh g À1 and up to 1720.6 mAh g À1 after 317 cycles under ac urrent density of 0.2 Ag À1 ). Meanwhile, ultralong cycling life is retained, even at high current densities (776.6 mAh g À1 at 2Ag À1 after 700 cycles and 584.8 mAh g À1 at 5Ag À1 after 800 cycles). Moreover,a tarate of 1Ag À1 ,t he average specific capacity is maintained at 661 mAh g À1 .T hus,t he hierarchical hollow NCM-NC hybridsw ith excellent electrochemical performance are ap romising anodem aterial for LIBs.[a] J.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

“…The Zif‐67/NG‐A‐derived CoO x /NG‐A and C/NG‐A showed excellent catalytic activity and electrochemical performance when acting as electrode materials for ORR and supercapacitors, respectively . Similarly, Cu‐Co‐MOFs/PGO, PB/3DG, Ni‐Co‐PBA/GA, Ni‐MOF‐74/NGO, and Zifs/GA were also obtained by immersing 3D interconnected carbon nanosheets in corresponding MOF precursors, turning out to be promising sacrificial templates for the synthesis of various metal oxides, metal sulfides, phosphides and carbons composites with 3D interconnected carbon nanosheets . The MOFs/GA can also be synthesized by a relatively simple process, during which the prefabricated MOF crystals were first mixed with the GO solution.…”

Metal–organic frameworks (MOFs) simultaneously containing metal ions and organic ligands have recently shown great potential for application in energy storage and conversion fields due to their controllable conversion into carbon materials or various metal species, which often exhibit superior electrochemical performance as electrode materials for energy storage and conversion. Nevertheless, the electrochemical energy storage performance of MOF derivatives can still be further enhanced through building composites with other functional materials. It is of great significance in developing new strategies of fabricating MOF composites to achieve electrode materials with improved charge transfer and electrochemical redox reaction kinetics. In this review, the novel design and strategies of MOF composites with various functional components are focused on, including carbon‐based materials (carbon nanotubes, graphene, etc.), metal oxides, 3D conductive substrates, polymeric materials, and the second MOFs and metal salts, especially their derivatives for energy storage and conversion fields. The key factors for controllable synthesis of various MOF composites and electrochemical performance enhancement mechanisms are discussed in detail. It is expected that this review will provide new inspiration for the development of MOF derivatives for energy storage and conversion.
