A green hydrothermal method has been developed for the synthesis of CdO₂ nanoparticles from Cd(OH)₂ powder and 6 vol.% H₂O₂ aqueous solution at 80–150 °C. The characterization results from X-ray diffraction, transmission electron microscopy, and thermal gravimetric and differential scanning calorimetry analysis disclosed that the resultant products were pure cubic phase CdO₂ nanoparticles with the sizes in the range of about 11–13 nm. The UV–vis absorption spectra revealed that the as-synthesized CdO₂nanoparticles had similar optical band gaps of about 3.85 eV. The Raman spectra of the as-synthesized CdO₂ nanoparticles displayed two obvious peaks at about 348 and 830/833 cm^–1, a characteristic of pyrite-type IIB-peroxides.
