Hydrothermal reduction route to Mn(OH)2 and MnCO3 nanocrystals

In this paper, uniform Mn(OH)(2) nanocrystals with diameters similar to20 nm and MnCO3 with diameters similar to60 nm have been obtained through a hydrothermal reduction route. Glycerol and glycol have been used as both reducing reagents of KMnO4 and stabilizing reagents of as-obtained nanoparticles. Due to their unique d(5) electrons and nanometer sizes, novel magnetic properties could be expected from Mn(OH)(2) and MnCO3 nanocrystals. (C) 2003 Elsevier B.V. All rights reserved.
