Ce-Y-palygorskite catalysts were prepared by chemical blending method. The effect of preparation conditions on catalytic performance of Ce-Y-palygorskite catalyst for NO decomposition was investigated...
室温条件下,在锆基的基础上加入其他金属离子配制了(Sm,Ce)/Zr基柱化剂。用该聚合阳离子柱撑钙基蒙脱石,室温下d001值为2.1~2.3m,焙烧300℃后,d001值为1.8nm,衍射峰敏锐对称,说明柱撑蒙脱石的热稳定性超过300℃。FTIR分析结果表明(Sm,Ce)/Zr基柱化剂和蒙脱石的Si—O四面体层形成了稳定的[Si—O]—[H(O)-Zr(Sm,Ce)]键,从结构上鳃释了(Sm,Ce...
