Composition and crystallinity of silicon nanoparticles synthesised by hot wire thermal catalytic pyrolysis at different pressures

Author: Scriba, Manfred R ; Britton, DT ; Arendse, C ; van Staden, MJ ; Härting, M Date: Apr 2009 The effect of pressure on the structure and composition of silicon nanoparticles synthesized by hot wire thermal catalytic pyrolysis (HW-TCP) of pure silane has been investigated. Light brown powders were produced at silane pressures of 10 ... Read more
Electrically active, doped monocrystalline silicon nanoparticles produced by hot wire thermal catalytic pyrolysis

Author: Scriba, Manfred R ; Britton, DT ; Härting, M Date: May 2011 Doped silicon nanoparticles have successfully been produced by hot wire thermal catalytic pyrolysis at 40 mbar and a filament temperature of 1800 °C, using a mixture of silane and diborane or phosphine. All particles are monocrystalline with ... Read more
Enhanced degradation of BPA in water by PANI supported Ag/TiO2 nanocomposite under UV and visible light

Author: Sambaza, S ; Maity, Arjun ; Pillay, K Date: Feb 2019 PANI supported Ag@TiO(sub)2 nanocomposite was synthesized via oxidative polymerization of aniline on Ag@TiO(sub)2. The Ag@TiO(sub)2 nanocomposite was synthesized by the photo reduction of Ag nanoparticles on hydrothermally synthesized TiO(sub)2 ... Read more
Nanostructured nickel (II) phthalocyanine-MWCNTs as viable nanocomposite platform for electrocatalytic detection of asulam pesticide at neutral pH conditions

Author: Siswana, MP ; Ozoemena, KI ; Geraldo, DA ; Nyokong, T Date: Aug 2010 This work reports for the first time that nanostructured nickel (II) phthalocyanine/multiwalled carbon nanotubes composite supported on a basal plane pyrolytic electrode (NiPcNP/MWCNT-BPPGE) could potentially serve as a viable platform for ...
