“…[ 11 ] Conversely, 2D nanomaterials such as transition metal oxides/sulfides have pseudocapacitance or battery behavior. [ 12–16 ] Transition metal oxides are very attractive due to their good chemical and mechanical stability, and the high capability in the field of supercapacitors predicted by theoretical calculations. However, the poor conductivity and p‐type behavior is an important disadvantage of metal oxides to overcome.…”

Transition metal oxides can be performant electrode materials for supercapacitors and alcohol oxidation if their conductivity and capacity are improved. Herein, an advanced nanocomposite material made of NiO‐Co3O4 on reduced graphene oxide (rGO) is synthesized by a one‐step hydrothermal method for supercapacitors and methanol/ethanol oxidation. It is demonstrated that the nanocomposite is a promising material for energy storage as NiO‐Co3O4‐rGO supercapacitor electrodes achieve a specific capacity of 149 mAh g−1 (894 F g−1) at a current density of 0.5 A g−1, the discharge time of 689 s, and excellent stability of 95% after 6000 cycles. Moreover, NiO‐Co3O4‐rGO shows a current density of 15 and 10 mA cm−2 in methanol and ethanol oxidation reactions, respectively, along with excellent stability.

“…Moreover, the highly ordered macropore arrangement in 3DOM ZIF67 was clearly evidenced from TEM images in Figure 1d and e, which consistent with the SEM results. The ordered macropores are beneficial to the uniform loading of sulfur and the alleviation of volume expansion during discharge/charge [16] . Furthermore, the elemental mapping shows homogenous Co, N, C and O elemental distributions in the as prepared 3DOM ZIF67 materials (Figure 1f).…”

The commercial application of lithium‐sulfur (Li−S) battery is greatly hampered by the shuttling of lithium polysulfide (LiPS). In this work, a double‐solution‐induced method is proposed to synthesize multifunctional three‐dimensionally ordered macro‐micro porous MOFs (3DOM ZIF67) as an efficient promotor to achieve excellent electrochemical performance. The unique ordered macro‐porous structure not only accelerates ion diffusion and charge transfer, but also enlarges the active interfaces. In addition, the nanometric ZIF67 unit with high porosity can achieve strong sulfur immobilization and catalysis by chemical interaction with LiPS, which vastly inhibited shuttle effect and promoted the rapid redox kinetics. As expected, the S/3DOM ZIF67 cathode achieves a high capacity of 920.7 mAh g−1 at 1.0 C and excellent cycle performance over 500 cycles. This design offers a feasible way to develop MOF‐based materials with efficient adsorption and electrocatalysis for high‐performance Li−S battery.

“…Among them, LiÀ S batteries have drawn a lot of attention due to their reduced costs, abundant resources, environmental friendliness. [2,3] The element sulfur (S) shows high specific capacity of 1675 mAh g À 1 and ultrahigh energy density of 2600 Wh kg À 1 after pairing with lithium anode, which is a prospective cathode material for LiÀ S batteries. [4][5][6][7] Nevertheless, there are still some problems such as the poor electrical conductivity of sulfur, diffusion of soluble LiPSs and volume expansion after Li 2 S formation, which limit the commercialization of LiÀ S batteries.…”

Lithium‐sulfur (Li−S) batteries have become a research focus for high‐energy‐density rechargeable batteries owing to the considerable theoretical energy density. However, the polysulfide shuttle and sluggish kinetics in lithium‐sulfur (Li−S) chemistry lead to low sulfur utilization, large polarization and rapid capacity decay, posing a fatal threat to the commercialization of Li−S batteries. Herein, we etched zeolitic imidazolate framework‐67 (ZIF‐67) with Ni2+ to manufacture NiCo‐LDH, which is used as a sulfur host material for lithium‐sulfur (Li−S) batteries. Benefited from the closely packed nano‐clusters and the hollow structure, the NiCo‐LDH could not only inhibit the lithium polysulfides (LiPSs) diffusion but also accelerate the redox reactions. Owing to these properties, the corresponding Li−S batteries exhibit a superior capacity (1540 mAh g−1 at 0.1 C) and high rate performance (485 mAh g−1 at 5.0 C). This work shows a promising way for layered double hydroxide as cathodes for Li−S batteries.
