【摘要】采用室温固相反应法合成了钼钨磷混配杂多酸铵[(NH4)3PW6Mo6O40.8H2O],用元素分析确定了分子组成;IR,XRD,TEM,TG-DTA及BET测试结果表明,(NH4)3PW6Mo6O40.8H2O为Keggin结构的纳米粒子,平均粒径为27 nm,比表面积为134.2 m2.g-1。形成纳米微粒后,杂多阴离子的热稳定性有所下降。更多还原

【Abstract】 The polyoxometate particles[（NH₄）₃PW₆Mo₆O₄₀·8H₂O] were synthesized by solid-state reaction at room temperature and were characterized by elemental analysis,IR,XRD,TEM,TG-DTA and BET.The results showed that the（NH₄）₃PW₆Mo₆O₄₀ exhibits Keggin structure with a surface area of 134.2 m²·g^-1 and the mean grain size of 27 nm.The stability of the hetoropolyanions decreased when nanoparticles formed.更多还原
