| Abstract: | A new kind of uniform hollow zeolite microspheres was successfully synthesized by an efficient strategy of post mild alkaline etching and characterized by SEM,TEM,XRD and N2 adsoption-desorption,etc.This novel product possessed hollow architecture,submicrometer-size,highly crystallized zeolite shells with penetrating mesopore structure and a low diameter-to-shell thickness ratio.Such hollow-structured zeolite microspheres show high capability for adsorbing dye materials. |
