Synthesis and Characterization of Composite Structure Zeolite Y
Y zeolite was synthesized form silica gel microsphere by in- situ hydrothermal method, with appropriate amount of other constituents, such as sodium silicate, water, without adding any organic additives. The as-synthesized samples were characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 sorption. The results show that the synthesized sample not only has a composite structure with zeolite Y and silica gel, but also retains the shape of silica gel microsphere. The pore distribution of the composite materials indicated that the composite material contains two types of pore that are micropores and large pores.
