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.

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。
