ABSTRACT

Lithium composite oxide powders are very important microporous materials. They have been used widely as bulk materials in catalysis, separations, chemical sensors and batteries, due to their unique tunnel structures and useful properties. Novel methods have been developed to synthesize novel nanoscale lithium manganese oxides in order to modify their physical and chemical properties and to improve their catalytic applications. In the synthetic study of nanosize LMO, a combination of explosion synthesis and solid-state combustion reaction was used to prepare transition metallic oxide powders. Preparative parameters of synthesis, such as detonation pressures, detonation temperature, calcinations temperature and time, were investigated in these combination syntheses of nanometer powders.
