Abstract: Weed-like ZnO nanostructures with uniformity in size were prepared by inverse microemulsion. The characterization results revealed that each weed consisted of several nanowires which were about 1 μm in length, 40 nm in diameter. On the basis of the known standard molar formation enthalpy of the bulk ZnO, the relationship of standard molar formation enthalpy between nano ZnO and bulk ZnO was obtained by designing a thermochemical cycle according to thermodynamic potential function method. Combined with the microcalorimetry, the standard molar formation enthalpy of the as-achieved weed-like ZnO nanostructures at 298.15 K was calculated as (-315.15±4.99) kJ/mol.

Key words: Standard molar formation enthalpy, Microemulsion, Microcalorimetry, Nano ZnO, Thermodynamic potential function method
