The morphology analysis of MMZ, Na-zeolite, and synthetic pure Fe 3O 4 was observed by scanning electron microscopy (SEM). Since Fe 3O 4 is synthe-sized in-situ on the surface of Na-zeolite, it is not simply physically attached to Na-zeolite, and because of the abundant pores on the surface of zeolite, Fe 3O 4 can be uniformly and fully coated ...
