Nanozero valent iron and nickel particles of silica composite (SiO2/Fe/Ni) were prepared via sodium borohydride reduction of ferric chloride and nickel chloride mixed solution in the presence of surface-modified silica. The prepared nano-SiO2/Fe/Ni was characterised by transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectrometry and Brunauer–Emmett–Teller specific surface...
We report the size control of nickel nanoparticles (NiNPs) through thermolytic reduction. The NiNP size was found to be varying from mono to bimodal distribution as a function of the reaction temperature and time with a narrow size distribution of 2 to 20 nm. The NiNP size and shape have been followed by employing two different lipophilic alkaylamine ligands either hexadecylamine or oleylamine. X-ray...
Possibilities of the method of obtaining metal powders by means of thermal decomposition (or reduction) of their compounds during heating in a medium of a high-boiling organic liquid were investigated. A distinguishing feature of the approach proposed is the use of benzyl alcohol as the liquid medium, while the initial metal carboxylates with different lengths of the methylene chain were formates,...
Nanoparticles of Ru-Ni with a core-and-shell structure were synthesized as potential sensors in a single-step spray-pyrolysis process at 700-1000. The majority of the core consists of ruthenium, while the shell is predominately composed of nickel. An aqueous precursor containing ruthenium chloride and nickel chloride was nebulized by an ultrasonic atomizer to generate an aerosol. The aerosol droplets...
