Summary of This Work: A simple solvothermal strategy has been developed to synthesize highly stable, pure phased CoO and Co₃O₄ nanoparticles from Co(CH₃COO)₂·4H₂O precursor in ethanol solvent at 220 °C. The various phases of cobalt oxide (cubic CoO and Co₃O₄) with controlled size and morphologies viz, nanocubes, hexagonal platelets and nanospheres could be obtained viavarying only one parameter (either surfactant or reaction time) in this single synthesis method. XRD and HRTEM analyses revealed pure cubic phase CoO and Co₃O₄ nanoparticles. The formation and shapes of CoO nanoparticles are surfactant dependent, whereas the formation and morphologies of Co₃O₄ are time dependent. The optical absorbance studies showed two distinct broad absorption peaks and hence two optical band gaps for both CoO and Co₃O₄nanoparticles. CoO nanoparticles showed a wide band gap difference of 2.36 eV, while Co₃O₄nanoparticles were found to be semiconducting in nature with a 0.6 eV–1 eV band gap difference, which showed characteristic features of CoO and Co₃O₄ nanoparticles, respectively. CoO nanoparticles showed interesting magnetic behaviour due to intrinsic antiferromagnetic structure and uncompensated surface spins, which was confirmed by VSM and EPR studies.

Summary of this work: CeO₂ nanoparticles exposed in (100) and (111) surfaces have been synthesized and explored as a heterogeneous catalyst for the first time in the oxidation of para-xylene to terephthalic acid. The synthesis and catalysis reaction was environmental friendly, where water was used as thesolvent. Ceria nanoparticles were synthesized with controlled size of 15 nm and high surface area of 268 m² g⁻¹ magnitude. These particles were exploited as a novel heterogeneouscatalyst for aqueous phase oxidation of para-xylene to bypass all the hazardous steps involve in the manufacture of industrially important terephthalic acid. The result shows the formation of 30–40% terephthalic acid under mild reaction condition, i.e. at 70 °C in water, by avoiding the corrosive bromide promoter and acetic acid solvent. The recyclability studies reveal that the recovered ceria catalyst retained its activity in para-xylene conversion without the change in thefluorite crystal structure, crystallite size and morphology of CeO₂. At last, a radical mechanism for this particular catalytic activity of the catalysis reaction has been proposed based on the high surface area and the corresponding available exposed active (100) and (111) surfaces.
