Silicon carbide (SiC) nanowires were synthesized using lignin-phenolic resin (LPR) and silicon powder as raw materials. The morphology and structures of the nanowires were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The influence of reaction conditions on the growth of the nanowires was investigated by thermodynamic analysis. It was revealed...
A method is developed for growing three-dimensional hierarchic structures of porous graphenic carbon film/hollow carbon nanorods where porous graphenic carbon film is first synthesized followed by, growth of carbon nanorods. By annealing an amorphous carbon layer deposited underneath a nickel thin film at elevated temperatures, the porous graphenic carbon film forms on top via carbon diffusion and...
Nanoporous carbonaceous materials with high surface area were prepared by the pyrolysis of polymethyl (phenyl) siloxane resin (SR249) under vacuum at a controlled temperature (1250–1350°C) followed by leaching in hydrofluoric acid (HF). Their compositions and structures at different pyrolysis temperatures were investigated by X-ray diffraction, Raman spectroscopy, elemental analysis, transmission...
An in situ grown carbon interphase between C fibres and a SiC matrix has been produced by impregnation and pyrolysis of a polycarbosilane–xylene solution. The microstructures of the carbon interphase and the effects on the mechanical properties of the C fibre reinforced SiC (C/SiC) composites were investigated using transmission and scanning electron microscopy. It was found that the carbon interphase...
Desulfurization of diesel fuels with hydrogen peroxide was studied using activated carbons as the catalysts. Adsorption and catalytic properties of activated carbons for dibenzothiophene (DBT) were investigated. The higher the adsorption capacity of the carbons is, the better the catalytic performance in the oxidation of DBT is. The effect of aqueous pH on the catalytic activities of the activated...
