摘要： 采用溶胶-凝胶技术研究了ZrOCl2·8H2O掺杂对磷硅酸盐凝胶质子导电性能的影响. 结果表明, 掺杂ZrOCl2·8H2O能提高磷硅酸盐凝胶的质子电导率, 并且掺杂质量分数为0.97%时质子电导率达到最大值(σ130=2.38 S/m). 掺杂样品在相对湿度为40%条件下放置30 d后, 未发生H3PO4渗出现象, 其质子传导性能基本不变. 核磁共振谱结果表明, 掺杂ZrOCl2减少了磷硅酸盐凝胶结构中自由磷酸的形成, 提高了与四面体之间的化学结合力.

Abstract: Effect of ZrOCl2·8H2O doping on proton conductive properties of phosphosilicate gel was investigated by means of sol-gel method. The results prove that ZrOCl2·8H2O can increase proton conductivity of the gel, and that the sample with ZrOCl2·8H2O content of 0.97%(mass fraction) shows maximum proton conductivity of 2.38 S/m at 130 ℃. The doped samples, on which no H3PO4 were found to precipitate during storage under a condition of R.H.(relative humidity) 40% for a month, exhibited no apparent changes in proton conductive performances. NMR measurements revealed that introduction of ZrOCl2 to the gel could decrease the formation of isolated PO3-4 structural units and increase cross-linking between and tetrahedrons, thus resulted in an increase in both proton conductivity and chemical stability.
