对中小学师生冲突关系进行研究发现,中小学师生关系由和美走向冲突,部分师生冲突趋于恶化。冲突关系的形成是诸要素统一变化的过程,学生不满情绪的长期压抑是其诱因,权威合法性的消解是其关键,学生对教师不再充满期待是其根源,师生言行的对立与师生关系的疏离是其表征。而教师应对方式制约着冲突关系的形成,关爱是建立和美无冲突师生关系的最佳方式,沟通是消解冲突关系的最佳方式,回避会使其陷入危机,强制的滥用致其恶化。因此,应选择恰当的教师应对方式,消解学生的不满情绪,重建教师权威合法性,调整学生对教师的合理期待,以建构"以和为贵"的师生关系。

第九届新型太阳能材料科学与技术学术研讨会

作者： Rui wang changhua wang Xintong Zhang Key Laboratory of UV-Emitting Materials and Technology of Chinese Ministry of Education Northeast Normal University

Surface electron traps, involved in photocarriers generation, trapping, recombination, as well as reaction at surface, are the pivotal factors in photocatalytic process [1-3]. Hence, engineering of electron traps in semiconductor oxides is essential for promoting charge separation and improving reduction ability, to enhance photocatalytic activity. Herein, we construct a thin amorphous layer on the surface of commercial defective P25 by alcohol plasma. After alcohol plasma processing, the density of electron traps decreases. Moreover, the energy level of electron traps is upshifted, which means a stronger photoreduction ability of trapped electrons. In the meantime, without precious metal load, the hydrogen evolution rate of treated-P25 is 1.982 mmol·g-1·h-1, which is 124 times higher than commercial P25. Moreover, the apparent quantum efficiency(AQE) of treated-P25 is 3.382%, 38 times as commercial P25(0.089%). Therefore, an effective and convenient approach for engineering of electron traps to significantly enhance photocatalytic activity is provided, expected to be widely used.

High-humidity tolerance of porous TiO2(B)microspheres in photo thermal catalytic removal of NOx

引用

Chinese Journal of Catalysis 2020年第10期41卷 1622-1632页

作者： He Ma changhua wang Songmei Li Xintong Zhang Yichun Liu Key Laboratory of UV-Emitting Materials and Technology of Chinese Ministry of Education Northeast Normal UniversityChangchun 130024JilinChina

Semiconductor oxides are widely used to achieve photocatalytic removal of NOx(NO and NO2) species. These materials also exhibit enhanced oxidation ability in thermally assisted photocatalysis;however, many of them tend to be deactivated at high relative humidity(RH) levels. In the case of the benchmark P25 TiO2 photocatalyst, we observe a significant decrease in non-NO2 selectivity from 95.02% to 58.33% when RH increases from 20% to 80%. Interestingly, the porous TiO2(B) microspheres synthesized in this work exhibit 99% selectivity at 20% RH;the selectivity remains as high as 96.18% at 80% RH. The high humidity tolerance of the TiO2(B) sample can be ascribed to its strong water desorption capacity and easy O2 adsorption at elevated temperatures, which reflects the fact that the superoxide radical is the main active species for the deep oxidation of NOx. This work may inspire the design of efficient photothermal catalysts with application in NOx removal in hot and humid environments.
