Carbon-coated anatase TiO2 samples were prepared from the mixture of poly vinyl alcohol (PVA) and commercial TiO2 (P-25) with different mass ratios and heating temperatures. The samples were characterized by X-ray diffraction (XRD), field
emission scanning electron microscope (FE-SEM), energy dispersive spectrometer (EDX), transmission electron microscope (TEM),
and nitrogen adsorption analyses. The adsorption properties and photocatalytic activity of commercial and carbon-coated TiO2 catalysts were compared for the oxidation of methylene blue (MB) and bisphenol-A (BPA). It was interesting to find that the
transition from anatase to rutile was suppressed by carbon coating of TiO2 at high temperature up to 800 °C. The carbon-coated TiO2 samples have a higher surface area and a greater adsorption amount than commercial P-25 because of the thin layer of carbon
that covered TiO2. It was also observed that the photodecomposition efficiency was dependent on the crystallinity of the carbon-coated sample. 相似文献

由于欧盟标签法的强制实施及高昂的油价,导致许多研究致力于提高轮胎的燃油经济性。众所周知,如果轮胎的滚动阻力下降10%,那么燃油经济性可提高1%~2%。轮胎由胎面、胎侧、钢丝圈、内衬层和胎体组成,1条轮胎约50%的滚动阻力受胎面影响。 相似文献
