Through a facile hydrothermal method with special surfactant triethanolamine (TEA) followed by thermal treatment, monodispersed micro-/nanostructured Co3O4 powders unique morphology (cube) have been synthesized successfully as anode material for Li-ion batteries (LIBs). The regular microcubes (∼2.37 μm in the average side length) consist of many irregular nanoparticles (20–200 nm diameter, 30–40 thickness) bonded to each other, which greatly inherit and size precursor CoCO3. specific surface...
Propane direct dehydrogenation (PDH) is an attractive technology for propylene production that has received extensive attention. Molecular sieves with uniform porous structure, high thermal stability, and unique confinement capability have been proven to be ideal supports well-dispersed active sites generate efficient PDH performance. In this review, we describe the progress in synthesis performance of metal-molecular sieve catalysts, including metal-mesoporous silica, metal-zeolite,...
TMS used as high-capacity anodes in Li-ion batteries are thoroughly reviewed.
In this study, novel core–shell ellipsoidal MnCo2O4 powders with desired micro/nano-structure and a unique concentration gradient have been synthesized as anode material for Li-ion batteries. The special porous ellipsoid (2.5–4.5 μm in the long axis, 1.5–2.5 short 200–300 nm thickness of shell) is built up by irregular nanoparticles attached to each other, corresponding gradient, Co/Mn atomic ratios core shell are about 1.76:1 2.34:1, respectively. good performance, including high initial...
The application of nitrogen-doped porous carbon for sodium-ion batteries (SIBs) has attracted tremendous attention. Herein, a series edge-nitrogen enriched nanosheets (ENPCNs) are synthesized by annealing g-C3 N4 and glucose in sealed graphite crucible at different temperatures (T = 700, 800, 900 °C). Surprisingly, under the closed thermal treatment condition, ENPCNs-T possess high N-doping level (>12.62 at%) interlayer distance ranging from 0.429 to 0.487 nm. By correlating with N...
We report a facile synthesis of novel cobalt oxide (Co3O4) hierarchical nanostructure, in which crystalline core-amorphous shell Co3O4 nanoparticles with bimodal size distribution are uniformly dispersed on ultrathin nanosheets. When tested as anode materials for lithium ion batteries, the as-prepared electrodes delivered high storage properties comparing to other nanostructures, including reversible capacity 1053.1 mAhg(-1) after 50 cycles at current density 0.2 C (1 = 890 mAg(-1)), good...
Co<sub>9</sub>S<sub>8</sub> nanoparticles encapsulated in nitrogen-doped mesoporous carbon networks have been synthesized by annealing a cobalt containing metal organic framework with sulfur powders. The products exhibit excellent lithium storage properties.
Abstract Transition metal chalcogenides (TMCs) are widely used as energy storage materials, however, most studies have neglected the reconstruction process that occurs during operation. Thus, intrinsic mechanism of TMCs and identification modulation not adequately investigated. Herein, a proactive strategy for kinetics under nonoperating conditions is proposed, potentiostatic method developed. The effects three electrochemical techniques potentiostatic, cyclic voltammetry, galvanostatic on...
