The introduction of protrusions through P-doping into graphene is an effective strategy to enhance electrochemical performances in SIBs.
Monodisperse Fe3O4 hollow spheres with average diameter of 400 nm and shell thickness 60 were prepared through a one-pot solvothermal process the presence NH4Ac as structure-directing agent, novel gas-bubble-assisted Ostwald ripening was proposed to explain formation structures. According this mechanism, MnFe2O4 ferrite microspheres controlled particle size obtained using urea ammonia agents, porous 100 pore 10 by assistance bicarbonate ammonia. X-ray diffraction, scanning electron...
In this paper, a general strategy for synthesis of carbon-based core/ZnO-shell-type composite and hollow materials is reported. These include colloidal carbon spheres@ZnO nanospheres, ZnO−carbon "dandelions", branched Au−ZnO−carbon size-tunable ZnO spheres. As-synthesized "dandelions" exhibited color change, which originated from the surface plasmon resonance gold nanoparticles, showing their optical application. All products obtained show well photocatalytic activities have highest...
In this paper, single-crystalline Co3O4 hollow octahedral cages with tunable surface aperture were synthesized by the carbon-assisted carbothermal method. On basis of electron microscopic observation and structural analysis, all following factors, including precursor concentration, species precursor, intrinsic crystal structure products reaction, play key roles in formation structures. When as-prepared samples used as anode materials lithium ion batteries (LIBs), it was found that large...
Silicon-carbon (Si-C) hybrids have been proven to be the most promising anodes for next-generation lithium-ion batteries (LIBs) due their superior theoretical capacity (∼4200 mAh g-1). However, it is still a critical challenge apply this material commercial LIB because of large volume expansion Si, unstable solid-state interphase (SEI) layers, and huge internal stresses upon lithiation/delithiation. Here, we propose an engineering concept multiscale buffering, taking advantage nanosized Si-C...

Octahedral Cu2O crystals with an edge length about 1 μm were synthesized by reducing a copper-citrate complex glucose. The morphology and structure of particles greatly affected the concentration glucose, reaction temperature, time. When glucose increased from 0.6 to 1.6 M, could be changed octahedral single spherical polycrystals. time was prolonged 6 36 h, solid octahedra mixture hollow irregular Cu particles. After removing particles, pure obtained. formation mechanism discussed....
The reduction of CO 2 to chemical fuel driven by solar energy can not only meet the growing demand for renewable energy, but also balance carbon cycle in nature. However, current photocatalysts have low conversion due their poor light capture ability, narrow response range, and high recombination probability photogenerated carriers. Herein, a heterogeneous photocatalyst hollow structured ZnO/ZnS decorated with Pt nanoparticles is synthesized through hydrothermal process photodeposition...
Preparing Si/C composite material with uniformly dispersed Si particles and stable electrode structure remains a huge challenge. In this study, reinforced interfacial interaction (Si&AG) was successfully synthesized. Utilizing the HF-plasma technique, metallurgical large particle size evaporated nucleated, resulting in nanocrystallization uniform dispersion onto graphite surface. More importantly, robust but thin SiC layer formed at contact region ensures steadfast adhesion of graphite. As...

Uniform spherical assemblies, prepared facile solvothermal reduction in the presence NaCl, were composed ordered nanooctahedra with thickness about 80–120 nm. The formation mechanism (NaCl-assisted Ostwald ripening) has been investigated TEM/HRTEM/SEM/XRD methods. Surface morphologies spheres have finely modulated from rough smooth surface through altering...
