摘　　要：Controllable synthesis of uniform and single-crystalline CdMoO4 nano-octahedra has been successfully realized at large-scale by a facile reverse-microemulsion route at room temperature. The structures, compositions and morphologies of the as-prepared products were characterized in detail by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), respectively. According to the thermochemical cycle, the relationship between the standard molar enthalpy of formation of nano-CdMoO4 and bulk CdMoO4 was proposed for the first time. In combination with micro-calorimetry, the standard molar enthalpies of formation at 298.15 K of as-ynthesized CdMoO4 nano-octahedra were ob-tained.Controllable synthesis of uniform and single-crystalline CdMoO4 nano-octahedra has been successfully realized at large-scale by a facile reverse-microemulsion route at room temperature.
