Heterobimetallic mixed metal oxide (HMMO) nanoparticles and their applications
2004
The chemistry of HMMO (heterobimetallic mixed metal oxide) nanoparticles of the type ABO 3 (perovskite), AB 2 O 4 (spinel and antispinel) and AB 2 O 5 (pseudobrookite) has been discussed. Their preparation by the sol-gel route using mixtures of alkoxides, heterobimetallic alkoxides and heterobimetallic-μ-oxo alkoxides are described. Physical and chemical properties, with special reference to high surface area, morphology, crystal structure, catalysis and destructive adsorption studies, along with some important applications have also been discussed.
