Synthesis of 12SrOAl2O3 crystal encaging abundant active oxygen

Abstract

Nanoporous crystal was prepared by solid-stats reaction of mixture of Sr(OH)2 and γ- Al2O3 at 600°C. Lots of O- and O2- were detected by ESR measurement. The spin concentration of the sample that heated at 900°C for 24h in O2 atmosphere was 2.0X10X²⁰cm^-3.12SrO⋅Al2O3 phase was decompose SrO⋅Al2O3 and 3SrO⋅Al2O3 over 1000°C.
