An interesting shape evolution of Cu2O crystals, that is, from cubes, truncated octahedra, and finally to nanospheres was first realized in high yield by reducing the copper−citrate complex solution with glucose. X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FESEM), high-resolution transmission (HRTEM) techniques were employed characterize samples. We elucidate important parameters (including poly (vinyl pyrrolidone) (PVP) concentration, reaction time,...
Well-defined cuprous oxide (Cu2O) thin film electrodes were electrodeposited on indium-doped tin (ITO) substrates from a slightly acidic Cu(II) acetate solution. The morphologies of Cu2O tunable by altering the deposition potential, reaction time, solution temperature and NaCl concentration. In particular, evolved dendritic branching to cube-like with increasing A growth mechanism was proposed according experimental results. addition, photocurrent 0.06 mA cm−2, an open-circuit photovoltage...
Large-scale ZnO nanotube bundles were successfully synthesized by a single solution method at lower temperature. Every bundle is composed of closely packed nanotubes, with inner diameters ∼350 nm and wall thicknesses ∼60 nm, forms radiating structures. The influence the reaction time on size shapes samples was studied in detail, results revealed that plays an important role determining final morphologies samples. formation tubular structure may be due to selective dissolution metastable...
Actinomorphic tubular ZnO/CoFe2O4 nanocomposites were fabricated in large scale via a simple solution method at low temperature. The phase structures, morphologies, particle size, shell thickness, chemical compositions of the composites have been characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), energy dispersive spectroscopy (EDS), and transmission microscopy (TEM). as-synthesized uniformly dispersed into phenolic resin then mixture was pasted on...
The flowerlike ZnO nanorod bundles, consisting of closely packed nanorods with diameter ∼90 nm, have been successfully synthesized by a poly(ethylene glycol) (PEG)-assisted hydrothermal route at low temperature (80 °C). results characterized from FESEM, TEM, and SAED demonstrate that the structures are single crystals formed self-assembled nanoparticles. Further investigation formation mechanism reveals PEG-assisted process is vital to complex nanostructures. sensors based on nanostructures...
We have successfully fabricated hierarchical ZnSnO3 nanocages via a facile one-pot solution synthesis method. Field emission scanning electron microscopic and transmission results reveal that the cubic samples with hollow interior porous shells are cage-like structure side length of 200−400 nm, where subunits irregular-shaped nanoparticles. The time-dependent morphology has been investigated, possible formation mechanism these structures is proposed. Moreover, gas sensor based on exhibits...
A TiO2 nanotubes array film with nanowires directly formed on top (denoted as NTWs) was prepared by an anodization method (potentiostatic growth). Bi2S3 QDs were sensitized the CdS/TiO2 NTWs a simple successive ionic layer adsorption and reaction (S-SILAR). short-circuit photocurrent density of 2.16 mA cm−2 obtained under illumination AM 1.5 G.
