“…SAED indicates that obtained films are amorphous and no distinct peaks are observed. After thermal decomposition at 623 K for 900 s on air, which is the accepted procedure for obtaining nanostructures with likely catalytic properties from the amorphous layers [16], films show crystalline pattern (Fig. 4, b) and the observed diffraction lines match the reported values for the cubic Pd phase, as shown in Table 2.…”
The plasma-enhanced metalorganic chemical vapor deposition (PEMOCVD) was used to prepare palladium–based thin films starting with palladium (II) acetylacetonate precursor (Pd(acac)2) mixed with argon (carrier gas). To characterize chemical structure and morphology of deposited films Raman spectroscopy and electron diffraction techniques were used. The energy dispersive X-ray microanalysis (EDX) was applied to specify composition of films. The film thickness was estimated by ellipsometric measurements.
The obtained results show that the films have various composition depending on deposition parameters. It has been found that the thermal decomposition at 623 K of the films leads to the formation of fine 5 nm–10 nm size palladium nanoparticles, to which the catalytic activity is attributed.

“…Additionally, various TEM studies on the Pd x -C 60 compound suggest the possible presence of Pd nanoparticles (NPs) in the material. [21][22][23] The presence of metallic clusters was also evidenced for Ru x -C 60 compounds produced at higher temperatures from [Ru 3 (CO) 12 ]. 18,24 However, using TEM, Lavrentiev et al have observed the polymeric chains in the Co x -C 60 mixture, which inner structure has been evaluated as (-C 60 -Co-C 60 -) order.…”
We report a simple and original procedure for preparing Ru–C60 polymeric chains, which spontaneously self-assemble as polymeric spherical particles, and can be surface decorated with Ru nanoparticles.
“…The chemically synthesized Pd C 60 polymer [502] forms of large cubic particles with size ranges from 20 to 80 m, which are composed of a small spherical nanoparticles 20-200 nm in diameter, as observed by TEM analyses. It is been also observed that the thermal decomposition of the composite allows to obtain Pd nanoparticles [503]. It has been also proposed to synthesize the polymer from the molten state of [Pd 2 (dba) 3 ] (dba = dibenzylideneacetone).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
