DADD-Assisted hydrothermal synthesis of t-ZrO2 nanopartides
Tetragonal ZrO2 (t-ZrO2) nanoparticles (diameter: ca. 10 nm; BET-specific surface area: 100 m(2)/g) are hydrothermally prepared via crystallization of 1,12-diaminododecane (DADD)-hydrous zirconia gels at 230 degrees C for 3 days. The volume content of monoclinic phase is ca. 0.1. The surface-adsorbed hydrocarbon layer (ca. 3 wt%) is observed by FTIR and TGA. They account for the formation of our t-ZrO2 nanoparticles with high-phase purity.
