“…Facing the carbon emission issue, hydrogen can be used as not only a kind of clean and efficient fuel, but also crucial feed for carbon recycling reaction (e.g., CO 2 hydrogenation to chemicals, depolymerization of polyethylene). [1][2][3][4][5] In conjunction with electricity generated from renewable energy source such as wind and tidal power, electrochemical water splitting has been considered as one of the most appealing approaches for production of carbon-free hydrogen. However, the total efficiency of electrochemical water splitting is greatly limited by the oxygen evolution reaction (OER) at spectroscopic studies and theoretical calculations, the markedly different OER activity of these MOFs is attributed to the electronic structure of Co and thus the adsorption of reaction intermediate on Co site.…”

anode because of the sluggish reaction kinetics and high barrier for the formation of OO bond. [6,7] Noble metalbased catalysts such as IrO 2 and RuO 2 exhibit excellent OER activity, but their high cost and non-renewability limit the wide-spread applications. [8][9][10][11] Therefore, it is of great importance to develop costeffective and stable non-noble metalbased electrocatalysts. [12][13][14][15][16][17][18] Metal-organic frameworks (MOFs), with highly dispersed metal sites, intrinsic high porosity, and high internal surface area, have been considered as potential non-noble metal-based catalysts for OER. [19][20][21][22][23] Among the various MOFsbased OER catalysts, Co-based MOFs have received extensive attention due to the high activity and stability. [24,25] More importantly, the structural flexibility of most Co-based MOFs allows the design and fabrication of bimetallic MOFs with different second metal, leading to higher catalytic performance. [26][27][28][29][30][31][32] For example, Li et al. reported that the CoZn bimetallic MOFs could exhibit OER activity with the overpotential of 320 mV at a current density of 10 mA cm −2 due to dimensionality and pore-geometry. [33] Furthermore, Bu et al. reported that the CoNi bimetallic 2D-MOFs exhibited excellent OER activity with the overpotential of 240 mV at 10 mA cm −2 , thanks to the CoNi coupling effect and the unsaturated active sites. [34] However, although plenty of efficient Co MOFs-based bimetallic OER catalysts have been developed, to the best of our knowledge, the effect of different second metal on the OER catalytic performance of Co-based MOFs has not been systematically investigated. What is worse, it is inappropriate to compare the results in reported works directly, because the reported Co-based MOFs may be different in coordination environment, dimension, and amount of second metal.Herein, we introduce different metal (M = Ni, Cu, Zn) into typical Co MOFs (i.e., ZIF-67) and further study their catalytic performance for OER in alkaline media to uncover the secondmetal effect for Co MOFs. These MOFs were grown on conductive carbon cloth (CC) immediately through a one-step roomtemperature strategy (marked as CoM MOFs/CC). [35] The order of OER activity, which is reflected by overpotential and Tafel slope, for these Co-based MOFs is found to be CoZn MOF/CC > CoNi MOF/CC > CoCu MOF/CC > Co MOF/CC. Furthermore, by Co-based bimetallic metal-organic frameworks (MOFs) have emerged as a kind of promising electrocatalyst for oxygen evolution reaction (OER). However, most of present works forCo-based bimetallic MOFs are still in try-and-wrong stage, while the OER performance trend and the underlying structure-function relationship remain unclear. To address this challenge, Cobased MOFs on carbon cloth (CC) (CoM MOFs/CC, M = Zn, Ni, and Cu) are prepared through a room-temperature method, and their structure and OER performance are compared systematically. Based on the results of overpotential and Tafel slope, the order of OER activity is ordered in the de...

“…Moreover, 1D nanostructure arrays possess many superiorities such as providing more efficient pathway for electrons/ions transmission. In particular, assembling 1D components into 3D nanostructure reasonably can reinforce the mechanical stability effectively, wherein, multipath behind interlaced morphological characteristics can accelerate much more electronic transfer accordingly [20,21]. At the moment, it is a formidable task to assemble one-dimensional structure into 3D structure with regular arrangement on hierarchical porous carbonaceous.…”

Developing suitable electrode materials for electrochemical energy storage devices by biomorph assisted design has become a fascinating topic due to the fantastic properties derived from bio-architectures. Herein, zephyranthes-like Co 2 NiSe 4 arrays grown on butterfly wings derived three-dimensional (3D) carbon framework (Z-Co 2 NiSe 4 /BWC) is fabricated via hydrothermal assembly and further conversion method. Benefiting from its unique structure and multi-components, the obtained Z-Co 2 NiSe 4 /BWC electrode for supercapacitor delivers an excellent specific capacitance of 2,280 F•g −1 at 1 A•g −1 . Impressively, the constructed asymmetric supercapacitor using Co 2 NiSe 4 /BWC as positive electrode and activated butterfly wings carbon as negative electrode acquires a high energy density of 42.9 Wh•kg −1 at a power density of 800 W•kg −1 with robust stability of 94.6% capacitance retention at 10 A•g −1 after 5,000 cycles. Moreover, the Z-Co 2 NiSe 4 /BWC as anode for sodium-ion batteries exhibits a high specific capacity of 568 mAh•g −1 at 0.1 A•g −1 and high cycling stability (maintaining 80.1% of the second cycle after 100 cycles). The outstanding electrochemical performances are ascribed to that the synergistic effect of bimetallic selenides and N-doped carbon improves electrochemical activities and conductivity. One-dimensional (1D) nanoneedles grown on 3D porous framework increase the exposure of redox-active sites, endow adequate transmission channels of electrons/ions, and guarantee stability of the electrode during charge/discharge processes. This study will shed light on the avenue towards extending such nanohybrids to excellent energy storage applications.

High-energy sodium-ion batteries have a significant prospective application as a next-generation energy storage technology. However, this technology is severely hindered by the lack of large-scale production of battery materials. Herein, a self-standing film, assembled with SnS–Sn/multiwalled carbon nanotubes encapsulated in carbon fibers (SnS–Sn/MCNTs@CFs), is prepared using ball milling and electrospinning techniques and used as sodium-ion battery anodes. To compensate the poor internal conductivity of SnS–Sn nanoparticles, MCNTs are used to interweave SnS–Sn nanoparticles to improve the conductivity. Moreover, the designed three-dimensional carbon fiber conductive network can effectively shorten the diffusion path of electron/Na+, accelerate the reaction kinetics, and provide abundant active sites for sodium absorption. Benefiting from these unique features, the self-standing film offers a high reversible capacity of 568 mA h g–1 at 0.1 A g–1 and excellent cycling stability at 1 A g–1 with a reversible capacity of 359.3 mA h g–1 after 1000 cycles. In the sodium-ion full cell device, the capacity is stable at 283.7 mA h g–1 after 100 cycles at a current of 100 mA g–1. This work provides a new strategy for electrode design and facilitates the large-scale application of the sodium-ion battery.
