Description
→ Ca24A128O66 + 4H2
請求項2に係る発明の反応は、下記反応式で示される。
→ Ca24A128O66 + 2H2
請求項1および2に係る発明において、水素置換マイエナイトは、例えば、カトイト(Katoite)を水素雰囲気中で焼成することで得ることができる。この焼成温度は例えば500〜1500℃、より好ましくは1000〜1400℃であり、焼成時間は温度に応じて1分から24時間の範囲で適宜決められる。カトイトは、例えばアルミニウム粉体と水酸化カルシウムから公知の方法で合成することができる。水素置換マイエナイトおよびカトイトは上記以外の方法で合成されたものでも良い。
イ)カトイトの製造
まず、容量1リットルの反応器(セパラブルフラスコ)にイオン交換水200mlを入れた。つぎに、アルミニウム粉体(商品名#150、ミナルコ社製)9gと水酸化カルシウム(和光純薬工業社製)12gを反応器に投入し、全体を撹絆した。水素ガスの生成が終了した後、イオン交換水をろ過し、ろ取した固形分を、温度70℃で、空気下で乾燥した。こうしてカトイトを得た。
このカトイトを温度1300℃で、水素雰囲気中で2時間焼成すると、水素置換マイエナイト(Ca24A128O64 4+・4H−)が生じた。この焼成品サンプルについて、リガク社製X線回折装置MaltiFlexを用いてX線回折の測定を行い、島津製作所製UV3400を用いて可視−UV光の反射スペクトルの測定を行った。
図5に示す水素製造用試験装置の容量1リットルの反応器(セパラブルフラスコ)にイオン交換水200mlを入れた。つぎに、上記で得られた水素置換マイエナイト9gを反応器に投入して全体を攪拌しながら加温し、全体の温度を55℃に維持した。
実施例1の工程ロ)で得られた水素置換マイエナイト(Ca24A128O64 4+・4H−)に紫外線を照射することで導電性マイエナイト(Ca24A128O64 4+・4e−)を得た。紫外線の照射は低圧水銀灯を用いて、ランプからサンプルまでの距離6.5cm、照射時間60分で行った。
実施例1における工程イ)で得られたカトイトを温度1300℃、空気下で2時間焼成し、マイエナイト(Ca24A128O66)を得た。
