Growth mechanism of scales of SiC nanowires with/without ZnS powders at varying temperatures

Applied Physics A (Impact Factor: 1.7). 02/2009; 94(3):613-618. DOI: 10.1007/s00339-008-4868-5


The growth mechanism of scales of crystalline SiC nanowires (SiC-NWs) obtained by directly evaporating solid carbon on silicon
wafer with/without ZnS powders at varying temperatures is being discussed. More aligned SiC-NWs of small size and good crystalline
structure were formed when ZnS was used. Random SiC-NWs of big size and poor crystalline structure were obtained at conditions
free of ZnS. Furthermore, the improved crystalline structure and increased diameter of SiC-NWs were observed when the higher
temperature was employed.

    ABSTRACT: Bulk quantities of straight and curled cubic silicon carbide nanowires (3C-SiC NWs) are synthesized from the mixture of ZnS, Si, and C powders. The 3C-SiC NWs are wrapped by amorphous SiO2 shells with very thin thicknesses of less than 2.0 nm. The deionized water suspension of the as-made NWs shows a photoluminescence (PL) band centered at 548 nm, and a tunable violet–blue photoluminescence is observed as the excitation wavelength increases from 300 to 375 nm after the SiO2 shell is removed. The PL band at 548 nm relates to the SiO2 shell. Careful microstructural observation suggests that the tunable PL originates from the quantum confinement effect of 3C-SiC nanocrystallites with sizes of several nm at the turning of the curled NWs.

    ABSTRACT: Macroscopic SiC nanowires (SiCNWs) were successfully synthesized at the gram level (2–4 g h−1) by using a simple solid–vapor reaction of silicon powders and carbon oxides, assisted by ZnS. This results in a promising material for a wide range of applications. The obtained products possess a small size of 10–30 nm and a good single-crystal structure. In addition, a specific surface area of 1.6 m2 g−1 was achieved. A high electrochemical activity to H2 adsorption/desorption and methanol oxidation was observed from cyclic voltammograms in H2SO4 and H2SO4/CH3OH solutions after loading with 50 wt.% Pt. Furthermore, a high catalytic performance for oxygen reduction at ∼0.57 V and good chemical stability were displayed. The novel SiCNW-supported catalyst shows potential for fuel cells with long lifetimes.

    ABSTRACT: SiC nanowires were produced by pyrolyzing oil palm empty fruit bunch fibres infiltrated with tetraethyl orthosilicate. The effects of the concentration of TEOS (10%, 50% and 100%) and the pyrolysis temperatures (1250 °C, 1300 °C, 1350 °C and 1400 °C) were studied. An increase in TEOS concentration led to an increment in silica content. However, when TEOS was infiltrated into the fibres, the small sizes of the lumens in the oil palm fibres and low fluidity of TEOS resulted in lower amount of silica deposited onto the surface when the concentration was increased to 100%. This in turn resulted in a lower yield of SiC nanowires at higher TEOS concentration. When pyrolysis temperature was raised, there was a decrease in diameter but the lengths of nanowires reached tens of μm. The growth of the nanowires was attributed to the combination of solid-state reaction and vapour–solid growth mechanisms.
