摘要
A simple and inexpensive route for the preparation of LiMn2O4 using ovalbumin (egg white) as a gelating agent is described. Gelation of freshly extracted ovalbumin was effected by changes in ionic strength brought about by the addition of nitrate precursors to an aqueous solution of ovalburnin and substquent warming. This resulted in tiny pockets of precursor materials getting trapped in the matrix of the gelled ovalbumin. Heat treatment of the gelled mass yielded submicron-sized LiMn2O4 Crystals at temperatures as low as 400 degrees C. (C) 2008 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
