| Research Abstract |
Hydrothermal reaction by using metal-naphthenates as one of the starting compounds could producetransition metal oxides with unique particle morphology as follows. Hollow magnetite (Fe3O4) sphereswere synthesized successfully via a template-free hydrothermal reaction using Fe-naphthenate and LiOHas the starting compounds. The starting material, -Co(OH)2 prepared by hydrothermal reaction wascalcinated at different temperatures from 300 to 800°C in air and LiCoO2 particles with various sizeswere obtained. Hexagonal cobalt oxide (Co3O4) nanorings over a size range from 100 nm to 1 mmconsisting of cubic nanocrystals were obtained via a hydrothermal method using as-prepared -Co(OH)2nanosheets as the precursors. A probable mechanism of formation of the hexagonal Co3O4 nanorings isproposed on the basis of time-dependent experimental results. Metal-dispersed porous carbon wasprepared from phenolic or furan resin mixed with Co or Ni naphthenate. The porous carbons preparedfrom phenolic or furan resin with Co or Ni naphthenate have specific surface area of approx. 400m2/g.
