Description
先ず、少なくとも、金属酸結晶層の原料であるチタンアルコキシド化合物および/またはニオブアルコキシド化合物と、界面活性剤として両端にアミノ基を有する脂肪族ジアミンを溶媒に添加する。好ましくは、溶媒中に金属アルコキシド化合物と含窒素ドープ剤を溶解した後に、界面活性剤を添加する。
次に、得られた反応混合液を水熱反応に付す。
水熱反応終了後、必要に応じて、本発明の薄片様層状化合物を濾過や遠心分離などにより単離してもよい。また、単離された薄片様層状化合物を洗浄してもよい。洗浄には、水、エタノールなどのアルコール、およびこれらの混合溶媒を用いることが好ましい。
蒸留水(50mL)へドデカンジアミン(1.00g)を溶解した。別途、チタンテトライソプロポキシド(3.55g)とトリエタノールアミン(3.73g)を混合した。これら溶液を混合し、さらに蒸留水を加えて100mLの溶液を得た。当該反応混合液におけるチタンテトライソプロポキシド:ドデカンジアミンのモル比は、1:2.5である。
上記製造例1において、チタンテトライソプロポキシド(3.55g)の代わりにニオブエトキシド(3.98g)を用いた以外は同様にして合成を行った。
上記製造例1において、金属アルコキシド化合物であるチタンテトライソプロポキシドの使用量を、界面活性剤であるドデカンジアミンに対してモル比率で5倍に変更した以外は同様にして、粉末を調製した。得られた粉末試料のX線回折結果を図5に示す。
上記製造例1〜2で得られた本発明に係る薄片様層状化合物と、市販の光触媒用酸化チタン粉体(石原産業社製,製品名「ST−01」)について、紫外可視分光光度計を用いて拡散反射スペクトルを測定した。結果を図6に示す。
上記製造例1〜2で得られた本発明に係る薄片様層状化合物と、市販の光触媒用酸化チタン粉体(石原産業社製,製品名「ST−01」)について、下記化学構造式を有するメチレンブルーに対する吸着特性を試験した。
上記製造例1〜2で得られた本発明に係る薄片様層状化合物について、光触媒活性を試験した。また、対照として、市販の光触媒用酸化チタン粉体についても同様に試験した。
