Chinese Journal of Chemical Engineering 2016年第8期24卷 1112-1116页

Hierarchical dendritic micro–nano structure Zn Fe_2O_4 have been prepared by electrochemical reduction and thermal oxidation method in this work. X-ray diffractometry, Raman spectra and field-emission scanning electron microscopy were used to characterize the crystal structure, size and morphology. The results show that the sample(S-2) is composed of pure ZnFe_2O_4 when the molar ratio of Zn^(2+)/Fe^(2+)in the electrolyte is 0.35. Decreasing the molar ratio of Zn^(2+)/Fe^(2+), the sample(S-1) is composed of ZnFe_2O_4 and α-Fe_2O_3, whereas increasing the molar ratio of Zn^(2+)/Fe^(2+), the sample(S-3) is composed of ZnFe_2O_4 and Zn O. The lattice parameters of ZnFe_2O_4 are influenced by the molar ratio of Zn^(2+)/Fe: Zn at excess decreases the cell volume whereas Fe at excess increases the cell volume of Zn Fe_2O_4. All the samples have the dendritic structure, of which S-2 has micron-sized lush branches with nano-sized leaves. UV–Vis diffuse reflectance spectra were acquired by a spectrophotometer. The absorption edges gradually blue shift with the increase of the molar ratio of Zn^(2+)/Fe^(2+). Photocatalytic activities for water splitting were investigated under Xe light irradiation in an aqueous olution containing 0.1 mol·L^(-1)Na_2S/0.02 mol·L^(-1)Na_2SO_3 in a glass reactor. The relatively highest photocatalytic activity with 1.41 μmol·h-1· 0.02 g^(-1)was achieved by pure ZnFe_2O_4sample(S-2). The photocatalytic activity of the mixture phase of Zn Fe_2O_4 and α-Fe_2O_3(S-1) is better than ZnF e_2O_4 and ZnO(S-3).

AS geographic literacy training is an education, national geographical education is essential content for Chinese citizens＇ literacy one of the indispensable key aspects of that training. Because of China＇s vast land area and the significance of the regional differences, it is difficult for students to receive a solid education regarding China＇s geography. In 1902, the government established the geography curriculum and began to incorporate the concept of geographical regionalization to facilitate the teaching of China＇s geography by publishing the first syllabi, which was modified later and put into use in 1904. Since 1904, numerous geog raphy textbooks have attempted to find an appropriate way to present China＇s geographical regionalization, as it is important for secondary students to have a clear understanding and appreciation for the different regional characteristics. Accordingly, the geographical region alization content is divided into four main phases： 1902 to 1927; 1928 to 1948; 1949 to 1986; and 1986 to the present. During these phases, the content related to China＇s geographical regionalization in secondary middle school geography textbooks has been gradually simplified and has adopted a more scientific foundation, thus leading to the present time where there are now four geographical regional areas. From this historical study, we find that while China＇s geographical regionalization has gradually matured, there are still some problems. For example, dividing the study into four regions to describe the panorama of China is too simplified, and the learning therefore becomes too scattered and haphazard, particularly qiven the new curriculum reform.

利用磁控溅射法对空心玻璃微球表面镀Al。研究了由镀Al空心玻璃微球-FeCo合金/环氧树脂制成的复合材料在2～18 GHz频段范围内的电磁特性,利用模型计算了所制备样品的微波反射率。结果表明,在镀Al空心玻璃微球和FeCo合金粉末总体积分数一定的条件下,随着镀Al空心玻璃微球与FeCo合金体积比的增加,复合材料介电常数实部ε′减小,虚部ε″变化不明显;磁导率的实部μ′和虚部μ″均减小;反射率峰值向高频方向移动。当镀Al空心玻璃微球与FeCo合金体积比2∶1时,涂层厚度为2 mm,吸收峰值达到-29.69 dB,其面密度仅为3.71 kg/m2,吸收率小于-10 dB的带宽达到2.4 GHz。由此可见,通过改变镀Al空心玻璃微球与FeCo合金的体积比,可以调节电磁参数,提高材料的吸波性能。
