The relationship of standard molar enthalpy of formation between nano and bulk BaMoO4 was obtained by designing a thermo chemical cycle according to thermodynamic potential function method, and the heat of reaction that nano BaMoO4 reacted with HCl could be gotten by microcalorimetry, based on the known standard molar enthalpy of formation, which was -1507.5 kJ•mol-1 of the bulk BaMoO4, standard molar enthalpy of formation for octahedron BaMoO4 nanostructures prepared by inverse microemulsion at 298.15 K was calculated as (-336.62±0.33) kJ•mol-1, the different value of two kinds of materials proved that the energy state of nano materials was higher and more unstable.

Key words: standard molar enthalpy of formation, thermodynamic potential function method, inverse microemulsion, nano BaMoO4, microcalorimetry
