摘要 根据热力学势函数法建立纳米钼酸钡与块体钼酸钡标准摩尔生成焓之间的关系,利用原位微量热技术获取纳米钼酸钡与盐酸反应的反应热,以已知的块体钼酸钡的标准摩尔生成焓-1507.5 kJ?mol-1为参考标准,求得由反相微乳液法制备的八面体纳米钼酸钡的标准摩尔生成焓为(-336.62±0.33)kJ?mol-1,两种材料标准摩尔生成焓数值的差异证明纳米结构比块体结构能态更高,更加不稳定. 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 kJomol^-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) kJomol^-1,the different value of two kinds of materials proved that the energy state of nano materials was higher and more unstable.
