摘　　要：采用泡沫碳化硅陶瓷作为载体,在其表面制备沸石分子筛涂层。首先,通过聚氨酯泡沫热解结合可控熔渗反应烧结制备泡沫碳化硅陶瓷。然后通过原位水热合成法在泡沫碳化硅陶瓷表面制备Silicalite-1沸石涂层。沸石涂层和泡沫碳化硅载体所组成的复合材料具有独特的微孔/大孔结构,高的比表面积和界面结合强度。这种材料将会在催化、吸附/分离领域有广泛的应用前景。SiC foam ceramics was prepared via a controlled template liquid silicon infiltration process. In situ synthesis technique was used in order to grow zeolite crystals onto the substrate. The final Silicalite-1/SiC foam ceramic composite possesses multimodal （micro-/macro-） porosity, unique architecture, high surface area and outstanding interfacial bonding properties. Such materials are expected to find application in catalytic and sorption/separation fields.
