“…1(j)). 22 The 3D network structure formed by the CNTs interleaved with each other enables the lowering of the permeation threshold and the construction of regional conductive pathways to further improve the electron transfer efficiency. 23 In addition, according to the analysis of the N 2 adsorption–desorption isotherms (Fig.…”

“…15 The values of Co/MnO@NC- X ( X = 1, 2, 3, 5 and 6) were 1.17, 1.11, 1.03, 0.99 and 0.92, respectively. The catalytic effect of Co nanoparticles 22 led to a gradual increase in the graphitisation of the samples with a progressive increase in the proportion of melamine. A higher degree of graphitization facilitates the strengthening of the conductive loss capability of EMW absorbing materials.…”

“…A hydrothermal method was used for the synthesis of the Mn-MOF nanowires. − Nitrilotriacetic acid (NTA, 3 mmol) and isopropyl alcohol (10 mL) were added to an aqueous solution (30 mL) of MnCl 2 (6 mmol). The mixture solution was magnetically stirred and then transferred into Teflon-lined stainless-steel autoclaves, followed by heating at 180 °C for 6 h. After cooling to room temperature, the product was washed with deionized water.…”

Beyond traditional paper, multifunctional nanopaper has received much attention in recent years. Currently, many nanomaterials have been successfully used as building units of nanopaper. However, it remains a great challenge to prepare flexible and freestanding metal–organic framework (MOF) nanopaper owing to the low aspect ratio and brittleness of MOF nanocrystals. Herein, this work develops a flexible and free-standing MOF nanopaper with MOF nanowires as building units. The manganese-based MOF (Mn-MOF) nanowires with lengths up to 100 μm are synthesized by a facile solvothermal method. Through a paper-making technique, the Mn-MOF nanowires interweave with each other to form a three-dimensional architecture, thus creating a flexible and free-standing Mn-MOF nanowire paper. Furthermore, the surface properties can be engineered to obtain high hydrophobicity by modifying polydimethylsiloxane (PDMS) on the surfaces of the Mn-MOF nanowire paper. The water contact angle reaches 130°. As a proof of concept, this work presents two potential applications of the Mn-MOF/PDMS nanowire paper: (i) The as-prepared Mn-MOF/PDMS nanowire paper is compatible with a commercial printer. The as-printed colorful patterns are of high quality, and (ii) benefiting from the highly hydrophobic surfaces, the Mn-MOF/PDMS nanowire paper is able to efficiently separate oil from water.

“…Li-S battery has become a high-profile energy storage and conversion device due to its high energy density and specific capacity. However, three main problems restricte the application of Li-S battery: (1) the conductivity of sulfur is extremely poor [1], with an electronic conductivity of only 5×10 −30 S cm -1 [2]. (2) During the charging-discharging process, the volume effect of the sulfur positive electrode is too obvious [3].…”

A nitrogen-phosphorus dual-doped porous spore carbon (NP-PSC) positive electrode matrix was prepared using native auricularia auricula as solid medium based on the principle of biomass rot. Yeast was introduce and cultured by the auricularia auricula solid medium. The freeze-drying and carbonization activation processes made the materials present a three-dimensional porous spore carbon aerogel properties. Yeast fermentation transformed auricularia auricula from blocky structure to porous structure and introduced nitrogen-phosphorus dual-doping. The physical and chemical properties of the prepared materials were characterized in detail. Electrochemical performance of NP-PSC in Li-S batteries was systematically investigated. Porous structure and heteroatom-doping improved the electrochemical performance, which is much superior to conventional activated carbon materials.
