Description
ここで、上記式中、FeOXは酸化鉄(化学式FenOmをFeOm/nと表記した)を表している。
以下に示す方法で液中でのFe304合成を行った。先ず、超音波洗浄器で脱気したイオン交換水20mlに、塩化鉄(II)(FeCl2)を2mmolと塩化鉄(III)六水和物(FeCl3・6H20)を4mmolとニッケルの塩化物とを溶かし,25%アンモニア水20mlに滴下していく。ニッケルの塩化物は、Fe:Ni=95:5になるように添加した。
ニッケルの塩化物の代わりに白金の塩化物を用い、昇温は373K(100℃)から2K/minで行ったことを除き実施例1と同様にして、Pt−Fe3O4を調製し、水素還元反応及び水蒸気酸化反応の試験を行った。すると、還元では、220℃で起こり始めた。また、水素の生成率は、373K(100℃)で25%、453K(180℃)で65%であった。本参考例における水素還元反応の結果を図6に、また、水分解反応の結果を図7に示す。
白金の塩化物の代わりにパラジウム(Pd)の塩化物を用い、参考例2と同様にして、Pd−Fe3O4を調製し、水素還元反応及び水蒸気酸化反応の試験を行った。すると、還元は、240℃で起こり始めた。また、水素の生成率は、393K(120℃)で26%、453K(180℃)で68%であった。本参考例における水素還元反応の結果を図8に、また、水分解反応の結果を図9に示す。
白金の塩化物の代わりにコバルトの塩化物(実施例4)、クロムの塩化物(参考例5)、アルミニウムの塩化物(参考例6)、ロジウムの塩化物(参考例7)を用いたことを除き参考例2と同様にして、各種金属添加Fe3O4を調製し、水素還元反応及び水蒸気酸化反応の試験を行った。本実施例および参考例における水素還元反応の結果を図10(コバルト)、12(クロム)、14(アルミニウム)、16(ロジウム)に、また、水分解反応の結果を図11(コバルト)、13(クロム)、15(アルミニウム)、17(ロジウム)に示す。
白金の塩化物を添加しない以外は参考例2と同様の方法で、鉄以外の金属が添加されていないFe3O4を調製し、水素還元反応及び水蒸気酸化反応の試験を行った。すると還元は、270℃で起こり始めた。また、水素の生成率は483K(210℃)で53%であった。本参考例のFe3O4を用いた水素還元反応の結果を図18に、また、水分解反応の結果を図19に示す。
本発明による調製法で得られた四酸化三鉄の代わりに、市販の四酸化三鉄(和光純薬工業製、BET比表面積3m2/g以下)を用い、実施例と同様に水素還元反応及び水蒸気酸化反応の試験を行った。すると、還元は、330℃で起こり始めた。また、水素の生成率は523K(250℃)で34%であった。このように、本発明の実施例と比較して、市販の四酸化三鉄では水素還元反応及び水蒸気酸化反応には、より高い温度を必要とすることが分かる。本比較例における水素還元反応の結果を図20に、また、水分解反応の結果を図21に示す。
