A series of nanostructured cobalt oxides have been prepared from a metal-organic precursor viz.[Co(fum)(H2O)4]·H2O (fum = fumarate) by using capping agents, ethylene glycol and polyethyleneglycol via thermal and solvothermal decomposition in ethanol and also by doping with RuCl3·xH2Ovia solvothermal route. The nano oxides were characterized by IR, UV-vis spectroscopy, powder XRD,SEM and TEM analysis. The nano oxides exhibit varied morphologies and particle sizes. The TEMimages reveal homogeneously distributed particles for all the oxides. The band gap energy values theRu-doped cobalt oxide was found to be lower than the generally accepted values.
