Abstract
【解決手段】ヒドラジン分解触媒を、コア層が、ニッケルを含有し、シェル層が、LaNi5を含有するコアシェル粒子として得る。このようなヒドラジン分解触媒によれば、効率良くヒドラジン類を水素および窒素に分解することができ、その結果、効率良く水素を得ることができる。
【選択図】図2
Description
(式中、R1は、炭素数1〜6のアルキル基、炭素数1〜6のフルオロアルキル基またはアリール基を示し、R2は、炭素数1〜6のアルキル基、炭素数1〜6のフルオロアルキル基、アリール基または炭素数1〜4のアルコキシ基を示し、R3は、水素原子または炭素数1〜4のアルキル基を示す。)
R5CH(COR4)2 (2)
(式中、R4は、炭素数1〜6のアルキル基を示し、R5は、水素原子または炭素数1〜4のアルキル基を示す。)
上記一般式(1)および上記一般式(2)中、R1、R2およびR4の炭素数1〜6のアルキル基としては、例えば、メチル、エチル、プロピル、イソプロピル、n−ブチル、s−ブチル、t−ブチル、t−アミル、t−ヘキシルなどが挙げられる。また、R3およびR5の炭素数1〜4のアルキル基としては、例えば、メチル、エチル、プロピル、イソプロピル、n−ブチル、s−ブチル、t−ブチルなどが挙げられる。
なお、分解においては、ヒドラジン類に、公知の酸性化合物やアルカリ性化合物などのpH調整剤を添加し、pH調整することもできる。
<金属塩溶液の調製>
オートサンプラー(GILSON製、GX−271LH)にて、下記金属塩溶液を調製した。
・硝酸ランタン(La(NO3)3)水溶液(濃度0.024mol/L)
・硝酸ニッケル(Ni(NO3)2)水溶液(濃度0.045mol/L)
<混合分散液の調製>
オートサンプラー(GILSON製、GX−271LH)にて、硝酸ランタン水溶液1.874mL(硝酸ランタン換算で4.5×10−5mol)および硝酸ニッケル水溶液8.994mL(硝酸ニッケル換算で4.0×10−4mol)を混合した。
<予備凍結>
分散液を、大気圧下、液体窒素(−196℃)で30分間冷却し、凍結させた。
<真空凍結乾燥>
