Preparation and Properties of Carbon/Zeolite Composites with Corrugated Structure

摘要: Composites of carbon/zeolite with corrugated structures were prepared by carbonization, steam activation and/or hydrothermal treatment paper. No zeolite formation resulted from conventional the carbonized and activated samples in NaOH solution but Na P1 was formed addition silica to solution. By contrast, zeolites A in-situ crystallization method (hydrothermal solid impregnated solution). With higher impregnating concentrations, longer reaction times temperatures, products changed sodalite- cancrinite-type compounds. Hydrothermal effective increasing specific surface area amorphous calcium aluminosilicate, also increased mechanical strength gluing together carbon fibers samples. The resulting showed enhanced adsorption for polar molecules such as ammonia, water vapor methanol due composites hydrophilic zeolites.
