- 摘要：The extraction behavior and phase behavior of TOPO (or TRPO)-kerosene/HCl-ZrOCl2 systems have been investigated. The middle phase with bicontinuous structure is first used as both the Zr(IV) source and the template to prepare mesoporous material just by precipitation with aqua ammonia under low temperature. By this method, crystal mesoporous ZrO2 powders with average d-values of 6.3 and 7.48 nm, respectively. have been obtained. TG-DTA, TEM, and XRD are adopted for the characterization of the synthesized sample. (C) 2003 Elsevier Inc. All rights reserved.
