Abstract
Nanocrystalline metal molybdates [i.e., AMoO 4, where A=Ca(II), Co(II), Cu(II), Ni(II), and Zn(II)] powders have been prepared from the complete evaporation of a polymer-based metal-complex precursor solution. The metal ions are in aqueous solution through complexion with triethanolamine (TEA) and are dispersed in a polymeric reagent composed of an aqueous solution mixture of sucrose and polyvinyl alcohol (PVA). The mesoporous carbon-rich precursor powders has been obtained on complete dehydration of the precursor solution and generates the respective metal molybdate phase after complete removal of carbonaceous residue at a heat treatment temperature less than 500 °C. X-ray diffractometry (XRD), Differential Thermal Analysis and Thermogravimetric Analysis (TG/DTA), and Transmission Electron Microscopy (TEM) have been used to characterize the preprecursors and the heat-treated final powders. The average particle sizes as measured from X-ray line broadening and transmission electron microscopy studies are around ∼10–30 nm. The particles having sizes of the same order with that of crystalline indicates the poor agglomeration of crystallites.
