  摘要：

  通过水热反应合成了前驱体氢锌矿，并通过在 400 °C 煅烧 15 分钟制备了分层组装的三维多孔氧化锌。三维多孔氧化锌由纳米片组装而成的微米球体组成。与二维多孔氧化锌纳米板相比，基于三维多孔氧化锌的传感器显示出更好的乙醇响应。在工作温度为 420 ℃、420 ℃ 和 340 ℃ 时，基于三维多孔 ZnO-2 的传感器对 100 ppm 丙酮、苯和乙醇的灵敏度最高，分别为 77.5、9.8 和 49.7。在工作温度为 420 ℃ 时，传感器对丙酮也有选择性。基于 ZnO-3 的传感器对 100 ppm 乙醇的灵敏度最高，达到 59.9，在 10-1000 ppm 范围内，响应随乙醇浓度的增加而线性增加。三维多孔氧化锌传感器良好的传感性能表明，分层组装的三维多孔氧化锌有望成为高灵敏度气体传感器的候选材料。

  Nanosized inorganic metal oxides as heterogeneous catalysts for the degradation of chemical warfare agents

  摘要：

  Nanosized inorganic metal oxides, such as TiO2, ZnO, gamma-Al2O3, are proposed as heterogeneous catalysts for the oxidative degradation of chemical warfare agents (CWA), particularly of organosulfur toxic agents, into oxidised products with reduced toxicity. The morphology, structural and textural properties of the catalysts were investigated. Furthermore, their catalytic properties were evaluated in the oxidative abatement of (2-chloroethyl)ethylsulfide, CEES, a simulant of sulfur mustard (blistering CWA). Their performance was also compared to a conventional decontamination powder and a commercial Nb2O5 sample. The metal oxides powders were then employed in the active oxidative decontamination of CEES from a cotton textile substrate, mimicking a real contamination occurrence. Remarkable results in terms of abatement and degradation into desired products were recorded, achieving good conversions and decontamination efficiency with Nb2O5, TiO2 and gamma-Al2O3, under very mild conditions, with hydrogen peroxide (as aqueous solution or as urea-hydrogen peroxide adduct), at room temperature and ambient pressure. In the aim of a real on-field use, the potential environmental impact of these solids was also evaluated by bioluminescence toxicity tests on reference bacteria (Photobacterium leiognathi Sh1), showing a negligible negative impact for TiO2, gamma-Al2O3, and Nb2O5. A major biotoxic effect was only found for ZnO. (C) 2016 Elsevier B.V. All rights reserved.

  composite are much higher than that of ZnO or α-MnO2. The main active species in the reaction progress were confirmed by electron paramagnetic resonance spectra and trapping experiments. According to the DFT calculation result and photothermal images, the enhanced catalytic activity is attributed to the photothermal and microwave-assisted effect. The addition of α-MnO2 improves the absorption of light and microwave

  摘要 为提高ZnO和α-MnO2的太阳能利用率和光降解​​效率，采用简便的方法制备了ZnO/MnO2复合材料。通过XRD、拉曼光谱、X射线光电子能谱、扫描电子显微镜、透射电子显微镜和紫外-可见漫反射光谱对材料进行表征。复合材料的光催化活性和微波辅助光催化活性远高于ZnO或α-MnO2。反应过程中的主要活性物种通过电子顺磁共振光谱和捕获实验得到证实。根据 DFT 计算结果和光热图像，催化活性的增强归因于光热和微波辅助作用。α-MnO2 的加入提高了复合材料对光和微波的吸收，这可以进一步加热催化剂。结果，加速了光生载流子的分离。最后，提出了提高复合材料催化性能的机制。

  The precursor hydrozincite was synthesized through hydrothermal reaction and hierarchically assembled 3D porous ZnO was prepared by calcination of the precursor at 400 °C for 15 min. The 3D porous ZnO was composed of micrometer spheres which were assembled from nanoflakes. The sensor based on 3D porous ZnO showed improved ethanol response compared to 2D porous ZnO nanoplates. The highest sensitivity of 77.5, 9.8 and 49.7, respectively, for the sensor based on 3D porous ZnO-2 were obtained for 100 ppm acetone, benzene and ethanol at the operation temperature of 420 °C, 420 °C and 340 °C, respectively. The sensor also show selectivity to acetone at the operation temperature of 420 °C. The highest sensitivity of the sensor based on ZnO-3 was of 59.9 to 100 ppm ethanol, the response increased linearly with the concentration of ethanol in the range of 10–1000 ppm. All the response and recovery times of the sensors were less than 20 s. The good sensing performance of the 3D porous ZnO sensor indicated that the hierarchically assembled 3D porous ZnO could be a promising candidate for highly sensitive gas sensors.
