Hollow zeolite fibers (abbreviated as HZF) have been successfully fabricated using electrophoretic deposition (EPD) technique with carbon fibers as templates and nanosilicalite-1 as building blocks, followed by removal of the templates by calcinating the zeolite- coated carbon fibers. Dense and complete zeolite deposition on carbon fibers is an essential premise for the preparation of intact HZFs. The formation of zeolite coating depends largely on the applied voltages and the surface charge of nanozeolites, which can be adjusted by the pH of the colloidal solution. In addition, deposition time and colloidal solution concentration also influence the deposit process. The structure of calcined HZFs has been characterized by XRD and IR.
