Abstract

We prepared a TiO2-P2O5 self-ordered, crystalline glass, mesoporous nanocomposite (CGMN) with water-holding capacity at an intermediate temperature region (130-200 degrees C). This TiO2-P2O5 CGMN showed the high proton conductivity of 2 x 10-2 S cm-1 at 160 degrees C under fully saturated humidification conditions (100% RH). Additionally, these conductivities were stable at intermediate temperature conditions. The TiO2-P2O5 CGMN may have a potential not only for the fuel cell electrolytes operated at intermediate temperature conditions but also for electrochemical devices, including electrochromic displays, chemical sensors, lithium rechargeable batteries, and others.

摘要

我们制备了一种TiO₂-P₂O₅自有序、晶态玻璃介孔纳米复合材料（CGMN），其在中间温度区域（130-200℃）具有持水能力。这种TiO₂-P₂O₅ CGMN在完全饱和加湿条件（100%RH）下于160℃时显示出2×10⁻² S cm⁻¹的高质子传导率。此外，这些传导率在中间温度条件下是稳定的。TiO₂-P₂O₅ CGMN不仅可能具有用于在中间温度条件下运行的燃料电池电解质的潜力，还具有用于包括电致变色显示器、化学传感器、锂可充电电池等在内的电化学装置的潜力。
