Using　the　industrialized　reagent　poly(ethylene　oxide)-poly(propylene　oxide)-poly(ethylene　oxide)　block　copolymer　surfactant　(P123)　as　a　template　and　zirconium　oxychloride　(ZrOCl2)　as　the　zirconium　source,　ZrO2　mesoporous　materials　were　synthesized　in　aqueous　solution　by　the　sol-gel　method　using　a　material　skeleton　without　the　addition　of　SO42-　(or　PO43-).　The　materials　obtained　had　a　high　specific　surface　area　(156　m2/g),　narrow　pore　size　distribution　and　adjustable　pore　diameter.　The　results　indicate　that　the　introduction　of　acetyl　acetone　is　disadvantageous　in　synthesizing　ZrO2　mesoporous　materials,　and　will　result　in　the　destruction　of　the　mesoporous　structure.　By　changing　the　aging　times　and　dissolving　temperatures,　the　pore　sizes　and　channel　architectures　could　be　adjusted,　but　the　excess　stirring　temperature　could　not　cause　the　formation　of　a　porous　structure.　With　the　increase　of　calcining　temperatures,　the　diameter　of　pores　increases　and　the　specific　surface　area　decreases.　However,　the　channel　shapes　hardly　change　and　retain　a　mesoporous　structure.
