These three-dimensional networks were synthesized using the chemical vapor deposition (CVD) method in a one-step synthesis strategy13,29,30,31,32, a hybrid CVD method on templates33,34,35,36 or through electron beam irradiation at high temperatures37,38. Synthesis of carbon sponges was ...
Abstract Carbon nanotubes were synthesized through a chemical vapor deposition method using MnCl 2as catalytic precurs or.The products were characterized by electron microscope and energy 2dispersive X 2ray spectrometer.The conditions for success ful synthesis of carbon nanotubes were studied.K ey w ...
The Ohaus Scout Pro SP202US digital scale used has 200 g weighing capacity with precision of 0.01 g. 2.2.1. Synthesis of FeCo/CaCO3 catalyst The bimetallic catalyst, FeCo on CaCO3 support was prepared as described in the literature by wet impregnation method (Afolabi et al., 2011). ...
Using the CVD method, CNTs can either be grown by the floating catalyst method [9], [10] or over catalysts deposited on solid supports [11], [12]. In both the cases, transition metal catalyst nanoparticles are considered to be the nuclei and potential sites for the growth of CNTs at ...
(a) Schematic process for the synthesis of the hexagonal multilayer MoSe2 nanoparticles with MoO3 and Se sources. (b) Optical microscope images of the as-grown MoSe2 multilayers and (c) as-grown MoSe2 bilayer on SiO2/Si. The insets show the AFM height profile of the as-grown MoSe2 ...
it needs to be fabricated in an economically viable manner and at the same time provides the necessary quality for relevant applications. Graphene and carbon nanotubes are no exception to this. In both cases, chemical vapor deposition (CVD) has emerged as the dominant synthesis route since it is...
Compared to the standard data, no peaks assigning to crystalline impurities appear, indicating that pure VO2 (B) can be achieved by this synthesis method. Note that the intensity of the 2θ peak at 25.2° corresponding to the (110) crystal plane demonstrates the obtained VO2 (B) with a ...
