Single-crystalline SnO2 microcubes were grown using the hydrothermal method without any catalyst. X-ray diffraction (XRD) patterns and energy dispersive X-ray (EDX) analysis verified that the cubes are tin dioxide SnO2. Their morphology and structure was studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and Raman 5m...

Novel core-shell nanostructures comprised of cubic sphalerite and hexagonal wurtzite ZnS have been synthesized at 150°C by a simple hydrothermal method. The results of HR-TEM and SAED investigation reveal that the cores of hexagonal wurtzite ZnS (ca. 200 nm in average diameter) are encapsulated by a shell of cubic sphalerite ZnS. The FE-SEM image of the nanomaterials shows a surface tightly pac...

in the present work, we report a suitable approach for the preparation of batio3 nanostructures via the hydrothermal condition using dolapix et85 as surfactant. the powders were investigated by x-ray diffraction (xrd), scanning election microscopy (sem), energy-dispersive x-ray spectroscopy (edax), field emission transmission electron microscopy (fetem), selected area electron diffraction (saed...

Graphitic carbon nanocoils with a high degree of crystallinity have been synthesized by using as intermediates hydrothermally carbonized samples (here denoted as hydrochar) obtained from three representative saccharides (glucose, sucrose and starch). The hydrochar samples were converted to graphitic nanocoils at moderate temperatures (900oC) using nickel nanoparticles as a graphitization cataly...

Hollow polyhedral graphite particles with 200~400 nm in diameter have been synthesized by heating oxalic acid, ferrocene and metallic magnesium at 580 °C, typically forming diamond-like octahedral structure. Combined with SEM, TEM, SAED patterns, and Raman spectroscopy, it was shown that the surface of graphite polyhedrons is composed of approximately 30-40 graphene shells; the fouror sixfold s...

In the present paper, ZnO nanorods with the mean size of 50 nm× 250 nm were successfully synthesized via a hydrothermal synthesis route in the presence of cetyltrimethylammonium bromide (CTAB). ZnCl2 and KOH were used as the starting materials and zinc oxide nanorods were obtained at 120 ◦C for 5 h. The product was characterized by means of X-ray powder diffraction (XRD), transmission electron ...

Hollow PtAg alloy nanospheres were synthesized via galvanic replacement reaction between silver nanoparticles and K2PtCl4 at 60 C. Their morphology, composition and structure were characterized by UV-vis, XRD, TEM, HRTEM, SAED, EDX and XPS. It was found that the shell thickness and roughness could be controlled by varying the amount of Pt precursor solutions. Compared with commercially availabl...
