Chevrel phase compounds have attracted increasing attention as electrochemical energy storage materials and electro-catalysts. Benefiting from their unique crystal structure, Chevrel phase compounds can not only function as the host structures for reversible intercalation of a broad range of cations, but also exhibit high catalytic activity in electrochemical reduction reactions. Here we provide an overview of recent progress in the development of Chevrel phase materials including new understanding of structural features, synthetic methods, and electrochemical properties. A brief conclusion and perspectives on the future development of Chevrel phase materials are also provided.

沸石具有良好的吸附性能和离子交换特性,对去除水中的重金属离子具有廉价、高效的优点。利用天然沸石矿物作为吸附材料,探讨了在不同条件下对干扰分选过程的多种重金属离子的去除效果和去除机制,研究了其在静、动态条件下去除模拟尾矿渗滤液中重金属离子的性能和机理。单一重金属离子静态吸附实验结果表明,沸石对Pb^(2+)、Cu^(2+)、Mn^(2+)、Zn^(2+)均有较好的去除效果,对4种重金属离子的吸附能力大小为Pb^(2+)> Cu^(2+)> Zn^(2+)> Mn^(2+)。混合离子静态吸附实验结果表明,在任意初始质量浓度下,Pb^(2+)在沸石上的吸附量均远大于Cu^(2+)、Zn^(2+)和Mn^(2+)。4种离子的吸附过程均符合Langmuir等温模型,属于单分子层吸附,准二级动力学模型能较好地描述沸石吸附4种重金属离子的过程,沸石在离子交换、表面静电和断键络合的共同作用下去除重金属离子,由于存在竞争吸附,沸石对相同价态不同阳离子的吸附能力存在较大差异,这主要受不同阳离子的水合半径的影响。动态条件下沸石对Cu^(2+)、Mn^(2+)、Pb^(2+)、Zn^(2+)的去除分别在102 h、64 h、900 h和78 h达到平衡,沸石的有效工作时间较长,可作为渗透反应格栅(PRB)的介质材料用于多金属矿尾矿渗滤液污染地下水的原位修复,具有良好的社会和经济效益。

高岭石改性及其对流化催化裂化催化剂性能的影响

中国材料大会2012

作者： Limei Wu Xiaoyu Wang Libing Liao guocheng lv School of Material Sciences and Technology China University of Geosciences

ISBN: (纸本)9783037856062

In this paper, the spent Activated Carbon (AC) which came from caramel plant was regenerated by the method of microorganism and chemistry. The optimal regeneration method was the combination of microorganism regeneration and NaOH regeneration. The optimal regeneration condition was treated by microorganism in 60 min at temperature of 35 ℃ and in NaOH (dosage was 6%). The optimal ultrafine grinding time was 5 h at 1200 rpm by adding 5 ‰ Triethanolamine, the effect of ultrafine grinding was better and the minimal size distribution was D90 3.82μm, D50 1.62 μm. the study ofAC surface modification was explored while combining the similar characteristics of AC and Carbon Black in its structure and composition. The possibility of reusing the spent AC was studied and the mechanical performance of rubber with modified AC was 434% higher than that of unmodified AC. The modified AC was characterized by Scanning electron microscope (SEM).

关键词： Spent AC Rubber filler Surface modification.

综述了高岭石的改性方法及其对高岭石理化性能和流化催化裂化(FCC)催化剂性能的影响。FCC催化剂的主要活性中心是表面酸位,主要裂化场所是催化剂的孔隙及表面。高岭石的酸改性或热改性增加了高岭石比表面积和表面酸量,改变了高岭石表面酸位种类以及孔结构,进而提高了高岭石基FCC催化剂的催化裂化性能。对国内外高岭石改性研究进行系统总结,可为高岭石的改性及其在FCC催化剂中的应用提供参考。

以珍珠岩细砂尾矿为主要原料,采用常温发泡的方法制备了新型的无机保温材料,重点探讨了岩棉纤维添加量对保温材料物理特性的影响。研究发现,随着岩棉添加量的增加,保温材料的内部气孔的平均孔径变大且均匀性变差,孔隙率呈现先升高后降低的变化规律;而抗压强度却不断提高,导热系数逐渐降低。结合常温发泡制备保温材料的机理,对上述规律进行了初步的解释。
