Therefore, it is believed that the materials prepared at 750oC is indeed LiMn2O4.The increase in the cell volumes is believed to be caused by a number of defects due to lack of oxygen atoms in the crystal structure.
As a result, Li-O bond distance of LiMn2O4 prepared at 750oC is easily separated from that of LiMn2O4 structure.

Catalysis Investigation of PET Depolymerization by ZnSrO2 under Microwave Irradiation* Lili Geng1,a, Chunhua Han1,b and Dong Zhang1,c,** 1Institute of Applied Chemistry, Wenzhou University, Wenzhou, Zhejiang, 325035, China alijiechunyu@163.com bfrankhch@163.com cdzhang@wzu.edu.cn Key words: SrZnO2; microwave; catalysts; PET depolymerization Abstract: In this paper, the powder of SrZnO2 was prepared by 1050°C solid-state reaction.
It was well known that metal oxide was an important catalyst, but the oxide of one metal was seldom used as catalyst, while composite metal oxides were usually used as catalysts for the special crystal structures, electromagnetic properties, and higher redox activities [5, 6].
SrZnO2 is composite metal oxide with the MⅡMⅡO2 type, which has a good layered structure in space.
