Surface and Pore Structure Modification of Mesoporous Nano-Zirconia Zeolites

Mesoporous nano-zirconia zeolite was synthesized by solid-state reaction-surfactant templating coupling method. Herein, solvent extraction could be used to take out the structure templates from zeolite pores because the interaction between skeletal Zr-O-Zr structure and PEO surfactants is very weak. Results indicated that nano-zirconia samples synthesized with solvent extraction borne even developed mesoporous structure and higher surface area but samples produced by calcination had micropore structure and higher thermal stabilities. SEM showed that the ordered apparent structure of the nano-zirconia samples could be stable even calcined at higher temperatures. It can be concluded that surface area and mesopore structures of nano-zirconia zeolites might be effectively modified by different template-extraction.
