  Catalytic oxidation of soot over alkaline niobates

  摘要：

  The lack of studies in the current literature about the assessment of alkaline niobates as catalysts for soot oxidation has motivated this research. In this study, the synthesis, characterization and assessment of alkaline metal niobates as catalysts for soot combustion are reported. The solids MNbO3 (M = Li, Na, K, Rb) are synthesized by a citrate method, calcined at 450 degrees C, 550 degrees C, 650 degrees C, 750 degrees C, and characterized by AAS, N-2 adsorption, XRD, O-2-TPD, FTIR and SEM. All the alkaline niobates show catalytic activity for soot combustion, and the activity depends basically on the nature of the alkaline metal and the calcination temperature. The highest catalytic activity, expressed as the temperature at which combustion of carbon black occurs at the maximum rate, is shown by KNbO3 calcined at 650 degrees C. At this calcination temperature, the catalytic activity follows an order dependent on the atomic number, namely: KNbO3 > NaNbO3 > LiNbO3. The RbNbO3 solid do not follow this trend presumably due to the perovskite structure was not reached. The highest catalytic activity shown by of KNbO3, despite the lower apparent activation energy of NaNbO3, stress the importance of the metal nature and suggests the hypothesis that K+ ions are the active sites for soot combustion. It must be pointed out that alkaline niobate subjected to consecutive soot combustion cycles does not show deactivation by metal loss, due to the stabilization of the alkaline metal inside the perovskite structure.

  A hydrothermal method was employed to prepare the sodium niobate (NaNbO3) nanocubes. We executed time dependent experiments to illustrate the formation mechanism of sodium niobate nanocubes. It was observed that the morphology of NaNbO3 nanocubes was dependent on the reaction time and 12hr reaction time was found to be suitable. Morphology, composition, structure and optical properties of sodium niobate nanocubes were evaluated by scanning electron microscope, X-ray energy-dispersive spectrometer, X-ray diffraction and UV-visible diffuse reflectance spectrometer. The photocatalytic activity of sodium niobate was studied for photocatalytic hydrogen production. It was anticipated that the sodium niobate (NaNbO3) cubes exhibited good photocatalytic activity under UV light irradiation using lactic acid as sacrificial agent. The cytotoxicity activity of sodium niobate nanocubes was studied as well at different concentrations (5 mg/mL, 3 mg/mL, 1 mg/mL, and 0.25 mg/mL) against human colon colorectal carcinoma cell line (HCT116) by MTT assay and EC50 was found to be 1.9 mg/mL. Sodium niobate proved to be a good DPPH free radical scavenging material, tested at different concentrations. It was noticed that peak intensity at 517 nm was decreased after 30 minute incubation, further supporting the antioxidant activity. This study will be useful for design and engineering of materials that can be used in biomedical applications and in photocatalysis.

  我们采用水热法制备了铌酸钠（NaNbO3）纳米立方体。我们进行了时间依赖性实验，以说明铌酸钠纳米立方体的形成机制。观察发现，纳米铌酸钠立方体的形态与反应时间有关，12 小时的反应时间是合适的。利用扫描电子显微镜、X 射线能量色散光谱仪、X 射线衍射仪和紫外-可见光漫反射光谱仪对铌酸钠纳米立方体的形态、组成、结构和光学性质进行了评价。研究了铌酸钠在光催化制氢方面的光催化活性。结果表明，铌酸钠（ ）立方体在以乳酸为牺牲剂的紫外光照射下表现出良好的光催化活性。通过 MTT 试验，研究了不同浓度（5 毫克/毫升、3 毫克/毫升、1 毫克/毫升和 0.25 毫克/毫升）的铌酸钠纳米立方体对人结肠直肠癌细胞系（HCT116）的细胞毒性活性，发现 EC50 为 1.9 毫克/毫升。在不同浓度的测试中，铌酸钠被证明是一种良好的 DPPH 自由基清除材料。研究人员注意到，在孵育 30 分钟后，517 纳米波长处的峰值强度降低，这进一步证明了铌酸钠的抗氧化活性。这项研究将有助于设计和制造可用于生物医学应用和光催化的材料。

  For sodium niobate (NaNbO3) ceramics containing in the nonpoled state about 30% of the ferroelectric Q phase, the temperature dependences of the dielectric constant ε and pyroelectric coefficient p are studied. The results obtained show that the transition from the Q phase into the high‐temperature nonpolar phase seems to be a diffuse one and the remanent polarization remains nonzero up to ≈370 °C

  对于铌酸钠（NaNbO3) 陶瓷在非极化状态下含有约 30% 的铁电 Q 相，介电常数与温度的关系ε和热电系数p被研究。获得的结果表明，从 Q 相到高温非极性相的转变似乎是一种扩散的转变，并且剩余极化在达到约 370 °C 时仍保持非零，即远高于材料的温度。p（时间）最大值（约 270 °C）。极化 陶瓷对于热释电传感器和 NaNbO 具有较高的品质因数3基材料有望在非制冷红外探测器中得到应用。
