Surface-Functionalized Boron Nanoparticles with Reduced Oxide Content by Nonthermal Plasma Processing for Nanoenergetic Applications
نویسندگان
چکیده
The development of an in situ nonthermal plasma technology improved the oxidation and energy release boron nanoparticles. We reduced native oxide layer on surface nanoparticles (70 nm) by treatment a hydrogen plasma, followed formation passivation barrier argon plasma-enhanced chemical vapor deposition (PECVD) using perfluorodecalin (C10F18). Both processes occur near room temperature, thus avoiding aggregation sintering High-resolution transmission electron microscopy (HRTEM), high-angular annular dark-field imaging (HAADF)-scanning TEM (STEM)-energy dispersive spectroscopy (EDS), X-ray photoelectron (XPS) demonstrated significant reduction concentration due to 2.5 nm thick coating PECVD treatment. These results correlated with thermal analysis results, which 19% increase metallic content after 120 min 15 perfluorodecalin. provided excellent against air humidity for 60 days. conclude lead amelioration characteristics storage life nanoparticles, benefits conducive nanoenergetic applications.

متن کاملNanoenergetic materials: boron nanoparticles from the pyrolysis of decaborane and their functionalisation.
The surfaces of boron nanoparticles 10-150 nm in diameter, prepared by gas phase pyrolysis of decaborane vapour at 1 atm and 700-900 degrees C, can be halogenated by treatment with Br2 or XeF2; the surface halogenation somewhat increases the onset temperature for the oxidation of the particles under O2.
