Fe2O3 nanocluster-decorated graphene as O2 electrode for high energy Li–O2 batteries
(2012)
Fe2O3 nanocluster-decorated graphene (Fe2O3/graphene) hybrids with controlled contents of Fe2O3 were prepared by a facile electrochemical process. These Fe2O3/graphene hybrids were tested as O2 electrodes for Li–O2 batteries, ...
In situ growth of Si nanowires on graphene sheets for Li-ion storage
(2012)
Si nanowires in graphene papers were successfully prepared by supercritical fluid–liquid–solid (SFLS) process, which showed high specific capacities and charge–discharge cycling stability as anode materials for Li-ion ...
Preparation and thermoelectric properties of sulfur doped Ag2Te nanoparticles via solvothermal methods
(2012)
In this work, n-type Ag2Te nanoparticles are prepared by a solvothermal approach with uniform and controllable sizes, e.g. 5–15 nm. The usage of dodecanethiol during the synthesis effectively introduces sulfur doping into ...
Oxidation-etching preparation of MnO2 tubular nanostructures for high-performance supercapacitors
(2012)
1D hierarchical tubular MnO2 nanostructures have been prepared through a facile hydrothermal method using carbon nanofibres (CNFs) as sacrificial template. The morphology of MnO2 nanostructures can be adjusted by changing ...
In situ formation of new organic ligands to construct two novel self-charge-transfer Pb(ii)-based frameworks
(2012)
Employing in situ-formed new organic ligands, two Pb(II)-based metal–organic frameworks were synthesized. Compound 1 possesses a 3D framework while compound 2 has a layered structure. Solid state UV-visible absorptions ...
Synthesis, crystal structure, and optical properties of a three-dimensional quaternary Hg–In–S–Cl chalcohalide : Hg7InS6Cl5
(2012)
A crystalline three-dimensional (3D) quaternary chalcohalide, Hg7InS6Cl5 (1), has been synthesized through a solid-state reaction under medium temperature. It is the first example in the family of the Hg–IIIA–Q–X (Q = S, ...
Flexible carbon nanotube papers with improved thermoelectric properties
(2012)
Although theoretical calculations indicate that the thermoelectric figure of merit, ZT, of carbon nanotubes (CNTs) could reach >2, the experimentally reported ZT values of CNTs are typically in the range of 10−3–10−2, which ...
