Description
<I>光触媒性酸化物と、この酸化物を構成する金属元素よりも酸素との親和力が小さい金属とにより構成されている。
<II>光触媒性酸化物は、金属の表面および内部の少くとも一部に、粒状および板状の少くとも一種の形態で、生成分散されている。
(実施例1)
ニッケルにチタンを3.0at%添加し、アルゴン気流中、1500℃にて溶解し、インゴットを作製後、皮剥きし、圧延により2mmの厚さの板状試料を作製した。この試料を酸化ニッケル粉、ニッケル粉、アルミナ粉末を等量ずつ混合した粉末中に埋め込み、アルゴン気流中、1050℃にて2時間保持し、その後550℃にて10時間保持した。1050℃の温度で酸化ニッケルから酸素が解離されることから、この解離生成された酸素がチタンを酸化することになる。このようにしてチタンの酸化性雰囲気が形成される。
(参考例)
金にチタンを1.5at%添加し、アルゴン気流中、1400℃にて溶解し、インゴットを作製後、圧延と焼鈍を繰り返し2mmの厚さの板状試料を作製した。この試料を走査型電子顕微鏡により観察したところ、粒子状の第二相が分散しているのが認められた。この試料のエックス線回折を行ったところ、金と金属間化合物TiAu4が認められ、金中に前記金属間化合物が分散しているのが、確認された。この試料を300気圧純酸素中950℃にて12時間の熱処理を行った。その後550℃にて10時間保持した。この板状試料をカッターで切断し、切断面を走査型電子顕微鏡により観察したところ、粒子が分散しているのが認められた。X線回折を行ったところ金のピークの他にアナターゼ型二酸化チタンおよびルチル型二酸化チタンのピークが認められ、これらの金中に光触媒作用を有するアナターゼ型二酸化チタン微粒子が分散していることが確認された。
(実施例2)
銅にチタンを1.5at%添加し、アルゴン気流中、1200℃にて溶解し、インゴットを作製後、圧延と焼鈍を繰り返し2mmの厚さの板状試料を作製した。この試料を酸化銅粉、銅粉、アルミナ粉末を等量ずつ混合した粉末中に埋め込み、アルゴン気流中900℃にて8時間の熱処理を行い、その後550℃にて10時間保持した。この板状試料の表面を走査型電子顕微鏡により観察したところ、粒子が均一に分散しているのが認められた。X線回折を行ったところ銅のピークの他にアナターゼ型二酸化チタンおよびルチル型二酸化チタンのピークが認められ、これらの銅中に光触媒作用を有するアナターゼ型二酸化チタン微粒子が分散していることが確認された。
