Description
なお、この発明において、酸化チタン光触媒体とは、バンドギャップ以上のエネルギーを持つ光により光触媒活性を示す酸化チタン化合物を意味する。
以下に実施例を示すが、この発明はこれらの実施例に限定されるものではない。
(紫外光照射)
光触媒体8mg/5mlのフェノール0.05mM溶液を調製し、この溶液にマグネチックスターラーで攪拌しながらブラツクライト(紫外光300〜400nm)を照射した。光照射に伴うフェノール濃度の変化をHPLC(高速液体クロマトグラフィー)で検出した。その結果、試料AはST01に近い紫外光照射によるフェノールの分解量を示した(図2)。
上記と同様に、光触媒体40mg/5mlのフェノール0.05mM溶液を調製し、この溶液にマグネチックスターラーで攪拌しながら、ブラツクライト(紫外光300〜400nm)の代わりに、450ワットタングステンランプとY−45フィルター(東芝製)と硫酸ニッケル水溶液を組み合わせ、可視光(430〜620nm)を照射した。その結果、ST01溶液ではフェノールの分解はほとんど認められなかったのに対し、試料Aの溶液ではフェノール量の減少が認められた(図3)。また、試料Aの溶液では、反応生成物であるp−ベンゾキノンが検出された(図4)。このことは、TiNを含む酸化チタンが可視光に対して応答することを示している。
Claims (2)
- TiX(式中、XはP、N、S2ならびにCから選ばれる少なくとも1種の非金属元素を意味する)化合物を、チタンテトラアルコキシド、チタンテトラハライド、チタンオキシサルフェート(TiOSO4)ならびにチタンオキシアセチルアセトナートから選ばれる少なくとも1種のチタン化合物と溶媒中で混合した後、加熱処理して非金属元素をドープした酸化チタン光触媒体を得ることを特徴とする酸化チタン光触媒体の製造方法。
- 請求項1に記載の酸化チタン光触媒体の製造方法であって、前記チタンテトラアルコキシドがチタンテトライソプロポキシドもしくはチタンテトラブトキシドまたは前記チタンテトラハライドがチタンテトラクロライドもしくはチタンテトラフルオライドであることを特徴とする酸化チタン光触媒体の製造方法。
