应的孔径分布图.从图6中可看到,样品的吸附-脱附等温曲线在低压区,曲线斜率较平缓,气体的吸附量小,在中高压区有明显的H2型迟滞环.这说明TiO2微球的空隙是由纳米粒子堆积形成的间隙孔[22]. 图6 不同nTi/nF比值下所制备的TiO2微球的氮气吸脱附测试图 Fig. 6 N2 adsorption–desorption test results of TiO2...氮气吸脱附测试结果表 Table 1 N2 adsorption-desorption test results of TiO2 microspheres prepared with different nTi/nF 2.7 光催化性能分析 为了考察不同nTi/nF比值对TiO2催化活性的影响,在紫外光照射下测试了样品光催化降解MB的性能,结果如图7所示,c为溶液吸光度......
Cu0.3Co2.7O4 microspheres with a wall thickness of about 100 nm were obtained. 3.3 Gas-sensitivity Figure 7 presents the nitrogen adsorption desorption isotherms and the corresponding pore size distribution......
spectroscopy. Results indicate that the adsorption, desorption, and reactivity properties of the TiO2 surface are strongly influenced in the presence of Pt nanoparticles. It is also proved that the photo... diffraction (XRD), scanning electron microscopy with X-ray microanalysis (SEM-EDS), thermos-gravimetric analysis, NH3 temperature-programmed desorption (NH3-TPD) were carried out to analyze the performance......
