摘要

摘要: 用T型沸石/聚酰胺酸悬浊液浸渍聚氨酯泡沫，然后在900 ℃下热处理制备原位担载的T型沸石/泡沫炭复合材料。用SEM，XRD和物理吸附仪等设备对所得样品进行表征。结果表明：所得复合材料为分级结构整体块状材料，泡沫炭基体的大孔平均尺寸约为500 μm；泡沫炭孔壁表面均匀镶嵌了大量沸石分子筛。所得复合材料的微孔孔径分布集中于0. 45 nm左右，比表面积达到328 m²/g。复合材料中沸石分子筛自身的结构特性和化学组成保持不变。

Abstract: T-type zeolite/carbon foam composites with a hierarchical structure were prepared by carbonizing polyurethane foam impregnated with a mixture of polyamic acid and T-type zeolite. The carbonization was conducted at 900℃ in flowing nitrogen. The as-prepared composites were examined using SEM, XRD and N₂ adsorption techniques. It has been found that the foam-like monolith consists of open cells with an average size of ca. 500μm, and T-type zeolites are anchored on the cell walls of the foam with their structure remaining unchanged even after heat treatment at 900℃. The zeolite/CF composites with a BET surface area of 328m²/g are microporous, and have a narrow pore size distribution centered at 0.45 nm.
