The Ni–P–CB (carbon black) nanocomposite coatings have been successfully deposited on an ABS plastic matrix via electroless
plating process. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) spectrometry techniques were employed to examine
the surface morphology and structure of the as-plated coating. Energy dispersive spectroscopy (EDS) was adopted to obtain
the component analysis of the Ni–P–CB composite coating, and the infrared emissivity of the coating was determined by the
IRE-I Infrared Emissometer. SEM and XRD results indicated that the nanoparticles were dispersed homogeneously in the Ni–P
coating; the result of EDS showed that the increased rate of CB content is in correspondence with its concentration. In the
case that CB concentration is lower than 4 g/L, the increase rate is sharp, whereas when the concentration is higher than
4 g/L, the increase rate is reduced significantly. Furthermore, study of infrared emissivity shows that the nanocomposite
coatings possessed low emissivity value. A comparison of the infrared emissivity dependence on surface resistivity obtained
from the analysis of the experimental results and those calculated using the Hagen–Rubens relation indicates that the Hagen–Rubens
relation is good for modeling the infrared emissivity of the Ni–P–CB nanocomposite coatings. 相似文献

Nanostructured titanium nitride (TiN) films with varying porosity were prepared by the oblique angle deposition technique (OAD). The porosity of films increases as the deposition angle becomes larger. The film obtained at an incident angle of 85° exhibits the best catalytic activity and sensitivity to hydrogen peroxide (H2O2). This could be attributed to its largest contact area with the electrolyte. An effective approach is thus proposed to fabricate TiN nanostructure as H2O2 sensor by OAD. 相似文献

TiO2 nanorod arrays (TiO2 NRAs) sensitized with CdS nanoparticles were fabricated via successive ion layer adsorption and reaction (SILAR), and TiO2 NRAs were obtained by oxidizing Ti NRAs obtained through oblique angle deposition. The TiO2 NRAs decorated with CdS nanoparticles exhibited excellent photoelectrochemical and photocatalytic properties under visible light, and the one decorated with 20 SILAR cycles CdS nanoparticles shows the best performance. This can be attributed to the enhanced separation of electrons and holes by forming heterojunctions of CdS nanoparticles and TiO2 NRAs. This provides a promising way to fabricate the material for solar energy conversion and wastewater degradation. 相似文献

以NH_3·H_2O and Fe(NO_3)_3·9H_2O为原料,采用共沉淀法得到前驱体,分别在150、250、350、450、550℃锻烧前驱体制备了Fe_2O_3,借助拉曼光谱、热重分析仪、X射线衍射、透射电子显微镜和紫外-可见光谱对其进行了表征。通过降解偏二甲肼废水,比较了不同锻烧温度下所得催化剂光催化的活性。结果表明,Fe_2O_3的结晶性和粒径大小同时决定光催化性能,锻烧温度小于450℃时,结晶性起决定作用,锻烧温度大于450℃时,粒径大小起决定作用,450℃锻烧的Fe_2O_3光催化降解偏二甲肼废水的效果最好。 相似文献
