ZrOCl2掺杂对磷硅酸盐凝胶质子导电性能的影响
Effect of ZrOCl2 Doping on Proton Conductive Performances of the Phosphosilicate Gels
摘要
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 PO34- structural units and increase cross-linking between [ PO4 ] and [ SiO4 ] tetrahedrons, thus resulted in an increase in both proton conductivity and chemical stability.关键词
