Abstract
【解決手段】SnP2O7が使用されるプロトン伝導体である。SnP2O7は、80℃ほど以上の高温で、無水物状態で10−1〜10−2S/cm水準の高いイオン伝導度を発揮する。また、SnP2O7は非水溶性であって高温で安定している。従って、SnP2O7は無加湿型プロトン伝導体、または高温無加湿型プロトン伝導体として作用できる。
【選択図】図1
Description
2O7の製造方法を提供する。本発明の方法は、二酸化スズまたは二酸化スズ水化物とリン酸とを反応させる段階とその反応生成物を熱処理する段階とを含む。
二酸化スズ水化物は次のような合成過程を通じて製造した。まず、塩化スズ(SnCl4)水溶液にアンモニア水を少しずつ添加することにより、水酸化スズ(Sn(OH)4)を生成した。このように得た水酸化スズ(Sn(OH)4)を水で洗いつつ濾過した後、80℃、130℃でそれぞれ5時間ずつ乾燥してから、550℃で2時間熱処理することにより、二酸化スズを合成した。
650℃での熱処理時間をそれぞれ1時間及び3.5時間としたことを除いては、実施例1と同じ方法で実施例2、3のSnP2O7粉末を製造した。
このように製造された実施例1〜3のSnP2O7粉末を使用し、3.14cm2の面積と1〜2mmの厚さとを有した円形ペレットを45Mpaほどの圧力を加えて製造した。SnP2O7ペレットの温度変化によるイオン伝導度を、4−プローブ伝導度測定装置を利用し、周波数100KHz〜1Hz、電圧100mVの実験条件下で、温度を常温から170℃まで変化させつつ測定してその結果を図2及び図3に示した。
塩化スズ(SnCl4)水溶液にアンモニア水を少しずつ添加することにより、水酸化スズ(Sn(OH)4)を生成した。このように得た水酸化スズ(Sn(OH)4)を水で洗いつつ濾過した後、80℃、130℃でそれぞれ5時間ずつ乾燥してから、550℃で2時間熱処理することにより、二酸化スズを合成した。このようにして得られたSnO2・xH2O(x:0〜2)と酸化チタン(多木化学株式会社製品)と105重量%のリン酸(ラサ工業株式会社製品)を1:0.1:2の重量比で混合した後、350℃で3時間撹拌した。このようにして得られた混合物を650℃で2時間熱処理して粉末を形成した。上記粉末を使用し、3.14cm2の面積と1〜2mmの厚さとを有した円形ペレットを45Mpaほどの圧力を加えて製造した。SnP2O7ペレットの温度変化によるイオン伝導度を、4−プローブ伝導度測定装置を利用し、周波数100KHz〜1Hz、電圧100mVの実験条件下で、温度を常温から170℃まで変化させつつ測定してその結果を図4に示した。
NAFION117を、30体積%過酸化水素水20mlと蒸溜水200mlとの混合液に1時間浸した後、80℃で1時間乾燥した。このように処理されたNAFION117を、98重量%硫酸水溶液5.42mlと蒸溜水200mlとの混合液に1時間浸した後、80℃で1時間乾燥した。このように処理されたNAFION117を蒸溜水で洗浄した後、80℃で1時間乾燥した。このような過程を経てNAFION117を洗浄した。洗浄されたNAFION117を、105℃の真空オーブンで1時間乾燥した後、80℃の蒸溜水に1時間浸した。このように含湿されたNAFION117の温度変化によるイオン伝導度を図2に示した。
