チタン粉末10mmol(0.479g)を秤量し、ここへ過酸化水素水(濃度30質量%)40gとアンモニア水(濃度30質量%)10gを加える。チタン粉末が完全に溶解するまで2時間以上攪拌しないで静置し、ペルオキソチタン酸錯体水溶液を調製した。このときチタンは発熱を伴って溶解するのでビーカーを水冷した。
チタンが完全に溶解したことを確認した後、グリコール酸15mmol(1.141g)を添加・溶解させ、20℃で12時間静置した。静置後、80℃で蒸発乾固させ余分な過酸化水素とアンモニアを除去し、グリコール酸チタン錯体を得た。
乾固物を蒸留水に再溶解させ、グリコール酸チタン錯体水溶液とし、この水溶液にアンモニア水(濃度30質量%)を、それぞれ2.0g、4.0g、10.0g添加し、pHを9以上に調整した。フッ素樹脂容器にこの水溶液を封入し、水熱処理用オートクレーブを用いて、200℃で24時間の加熱を行った。反応容器を冷却させた後、生じた沈殿をろ過又は遠心分離することにより取り出した。ろ過物を蒸留水で、洗浄液のpHが中性になるまで洗浄した後、乾燥させ、ブルッカイト型二酸化チタンを得た。加えた濃度30質量%のアンモニア水の量に対応して、得られたブルッカイト型二酸化チタンを、それぞれTiO2(2g、200℃)、TiO2(4g、200℃)、TiO2(10g、200℃)とする。
得られた試料を、常法に従って、銅Kαを用いた粉末X線回折パターンを測定した。結果を図2及び図3に示す。図2から分かるように、TiO2(2g、200℃)、TiO2(4g、200℃)、TiO2(10g、200℃)は、ICSD#036411のブルッカイト型二酸化チタンの構造よりシミュレーションによって作成した回折パターンと全て一致しており、それ以外のピークは観察されなかった。また、図2から分かるように、TiO2(2g、160℃)、TiO2(2g、200℃)、TiO2(2g、230℃)も、ICSD#036411のブルッカイト型二酸化チタンの構造よりシミュレーションによって作成した回折パターンと全て一致しており、それ以外のピークは観察されなかった。
上記方法で製造したTiO2(2g、200℃)を、透過型電子顕微鏡画像を図4に示す。平均粒径約100nmの凝集のない微粒子が得られたことが分かった。
上記の合成法で得られたブルッカイト型二酸化チタン(TiO2(2g、200℃))を図5に示す装置を用いて、NO分解による光触媒活性試験を行った。2ppmのNOガスと乾燥空気を100mLずつ混合し、初期NO濃度1.00ppm、流量200mL/分として反応器内に流通させた。試料は20×15×0.5mmのガラス製試料ホルダに充填し、反応器に設置した。光非照射下においてNO濃度が1.00ppmであることを確認した後、450Wの高圧水銀灯を光源として光を照射した。高圧水銀灯には冷却水を流した。
