以Cd(OH)(2)粉末和体积分数为6%的H_2O_2水溶液为原料，在80~150℃条件下，采用绿色水热法合成了Cd(OH)_2纳米颗粒。X-射线衍射仪、透射电子显微镜、热重和差示扫描量热仪的表征结果表明，合成的产物为纯立方相的纳米Cd_2O_2，尺寸约为11~13 nm。UV-Vis吸收光谱表明，合成的CDO2纳米粒子具有类似的光学带隙，约为3.85 eV。拉曼光谱在348和830/833 cm(-1)处有两个明显的峰，这是黄铁矿类型的IIB-过氧化物型的特征。(C)2010爱思唯尔B.V.保留所有权利。
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 degrees 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 CdO2 nanoparticles 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. (C) 2010 Elsevier B.V.
