Abstract
【解決手段】 バナジウム酸化物を多孔質担体に担持させた可逆性感湿材料において、前記多孔質担体として非晶質シリカを使用すると共に、非晶質シリカの平均細孔径を6nm以下とする技術的手段を採用した。
【選択図】 図4
Description
この実施例1においては、平均細孔径が2.5nmの非晶質シリカを担体として使用すると共に、この非晶質シリカを、バナジウムシュウ酸錯体(H2V2C6O14)を含む水溶液に含浸し、これを200℃まで加熱して水分(H2O)及びシュウ酸(C2O4H2)の成分を熱で分解して蒸発させることにより、非晶質シリカにバナジン酸(monovanadate)を担持させて感湿材料を作製した。
続いて、上記実施例1と同じく平均細孔径2.5nmの非晶質シリカを使用して作製した感湿材料(サンプル1)と、平均細孔径6nm及び平均細孔径10nmの非晶質シリカを使用して作製した感湿材料(サンプル2及びサンプル3)について室温での吸湿と400℃での加熱脱水を3回繰り返して、吸湿と加熱脱水処理の前後の拡散反射スペクトルを測定してデータを比較した。
