Abstract
A series of nano octahedral CdMoO 4 with different sizes were prepared by reverse-microemulsion method at room temperature, and the constitute, structure and morphology were characterized. Based on the essential difference between thermodynamic properties of nano CdMoO 4 and bulk CdMoO 4 , the equations for acquiring surface thermodynamic properties of nano CdMoO 4 were derived via combining the basic theory of chemical thermodynamics with thermokinetics theory. According to the derived equations, surface thermodynamic functions such as specific surface Gibbs free energy, specific surface enthalpy and specific surface entropy of the prepared nano octahedral CdMoO 4 at 298.15 K were successfully gained by in situ microcalorimetry. Briefly, this work presented an effective and general method to obtain thermodynamic functions of nano materials.
