Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

循环伏安实验表明：铬液流电池的电极反应非常复杂，在阳极存在Cr→Cr，Cr→Cr的氧化反应，在阴极存在Cr→Cr，Cr→Cr，Cr→Cr的还原反应；热处理的石墨电极和重铬酸钾处理的石墨电极能提高电极反应的活性和可逆性；在充放电实验中未处理的石墨电极发生严重腐蚀；分别用这两种方法处理过的石墨电极具有防止六价铬侵蚀的功能；铬离子在活化处理过的石墨电极上的反应活性和可逆性增加，可以认为：重铬酸钾溶液活化处理和加热处理后的石墨表面的含氧官能团增加，电极亲水性增强。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。

Two times hydrolyzation of Fe~(3+) and Cr~(3+) was firstly pointed out in the process of pillar preparation with hydrothermal method. In order to improve the thermal stability, Fe/Cr-Si-pillaring agent solution was synthesized by hydrolyzing Fe~(3+) and Cr~(3+) solution on the surface of silica sol, and Fe/Cr-Si-pillared montmorillonite (Fe/Cr-Si-PILM) was prepared with conventional method and hydrothermal method. Because the technical innovation of preparation is the best way to improve the PILM properties, two novel methods (Microwave method and Ultrasonication method) have been studied to synthesize Fe/Cr-PILM.In order to expand PILMs new application in the field of coal conversion, catalytic activity of Fe/Cr-Si-PILM catalyst in LongKou lignite and ShenHua coal residue liquefaction was discussed and characterized in the last part of this paper.

研究证明：蒙脱石的预处理是可行的，我们以预处理后的Ca-M为原料，研究并优化了PILM的水热法制备工艺，提出了金属离子的二次水解法；为了提高PILM的热稳定性，我们自制了硅溶胶，合成了Fe／Cr-Si三元复合柱化剂，并制备了Fe／Cr-Si-PILM；在PILM合成中，制备技术的革新是改进PILM性能的重要方法，为此我们探索了微波合成法和超声波合成法在制备Fe／Cr-PILM中的应用；最后，我们选择龙口褐煤和神华煤液化残渣为研究对象，探索了Fe／Cr-Si-PILM催化剂在煤炭液化中的应用，希望能开拓PILM应用的新领域。
