“…These results are similar to those obtained by Wang et al [19] who say that because of electron beam temperature the Pb-core expands moving from one extreme to another within ZnO-shell. Thermal expansion effect of partially Pb-filled nanotubes has also been studied by Lee et al [20] who tested the electron beam effect on the Pb inner core of the nanotubes. Only a few studies have reported obtaining of Pb(core)/ZnO(shell) nanowires using wet chemical synthesis based on their respective nitrates [19]; however, the technique employed in this study consists of a one-step vapor transport, decomposition, and condensation reaction assisted by microwave to prepare these nanostructures is reported for the first time.…”

In this study, Pb-filled ZnO nanowires [Pb(core)/ZnO(shell)] were synthesized by a simple and novel one-step vapor transport and condensation method by microwave-assisted decomposition of zinc ferrite. The synthesis was performed using a conventional oven at 1000 W and 5 min of treatment. After synthesis, a spongy white cotton-like material was obtained in the condensation zone of the reaction system. HRTEM analysis revealed that product consists of a Pb-(core) with (fcc) cubic structure that preferentially grows in the [111] direction and a hexagonal wurtzite ZnO-(Shell) that grows in the [001] direction. Nanowire length was more than 5 μm and a statistical analysis determined that the shell and core diameters were 21.00 ± 3.00 and 4.00 ± 1.00 nm, respectively. Experimental, structural details, and synthesis mechanism are discussed in this study.

“…The properties of lead dioxide are highly dependent on its method of synthesis, which affects the structure, morphology and phase composition. PbO 2 sub micrometer-sized hollow spheres and microtubes [20], lead oxide nanotubes [21], porous PbO 2 electrodes [22], lead oxide nanobelts [23], and lead dioxide films [24] have been synthesized by applying different synthesis routes. Liang Shi et al reported lead oxide nanosheets, scrolled nanotubes, and nanorods in a controlled way [25].…”

Micron sized hexagon-and flower-like nanostructures of lead oxide (α-PbO2) have been synthesized by very simple and cost effective route of anodic oxidation of lead sheet. These structures were easily obtained by the simple variation of applied voltage from 2-6 V between the electrodes. Lead sheet was used as an anode and platinum sheet served as a cathode. Anodic oxidation at 2 V resulted in the variable edge sized (1-2 μm) hexagon-like structures in the electrolyte. When the applied potential was increased to 4 V a structure of distorted hexagons consisting of some flower-like structures were obtained. Further increment of potential up to 6 V resulted in flower like structures of α-PbO2 having six petals. The diameter of the flower-like structures was ∼200-500 nm and the size of a petal was ∼100-200 nm.
