纳米AgBr热力学性质的测定及温度效应研究
|
摘要
通过测定溴化银纳米颗粒在水溶液中的电导率,结合溶解热力学理论,计算了纳米材料的溶解平衡常数.以块体材料为参比标准,获取了纳米AgBr的溶解热力学函数、表面热力学函数、偏摩尔表面热力学函数和规定热力学函数.文中结果为纳米AgBr在感光、催化、吸附等领域的应用提供了物理化学参数,对预测难溶盐类纳米材料溶解、催化、吸附等性质有重要的指导意义.
The conductivity of AgBr nanoparticles in aqueous solution is measured,and the equilibrium constants of the nanomaterials are calculated in terms of the theory of dissolution thermodynamics. The dissolution thermodynamic functions,surface thermodynamic functions,partial molar surface thermodynamics and prescribed thermodynamic functions of nano-sized AgBr are obtained using bulk materials as the standard of comparison. The results provide physical and chemical parameters for the application of nanometer AgBr in the fields of photosensitivity,catalysis and adsorption. This method can offer important guidance in predicting the properties of inso-luble salt nanomaterials such as dissolution,catalysis and adsorption.
