Description
例えば、特許文献1には、酸化チタン結晶の酸素サイトの一部を窒素原子で置換した可視光活性を有する光触媒材料が開示されている。
2Cu(I)+O2+2H+ → 2Cu(II)+H2O2
2Fe(II)+O2+2H+ → 2Fe(III)+H2O2
:4電子還元
4Cu(I)+O2+4H+ → 4Cu(II)+2H2O
4Fe(II)+O2+4H+ → 4Fe(III)+2H2O
あるいは
3Cu(I)+O2+4H+ → 2Cu(II)+Cu(III)+2H2O
4Fe(II)+O2+2H2O → 4Fe(III)+4OH−
このように、金属イオンドープ酸化チタン上に担持された銅二価塩のCu(II)イオンや鉄三価塩のFe(III)イオンは、酸素の多電子還元触媒として作用するものである。
O2+e− → ・O2 −
一方、本発明における光触媒材料は、可視光照射によって励起された光励起電子が、Cu(II)イオンやFe(III)イオンを介して酸素の多電子還元に消費され、上記のように過酸化水素あるいは水を生成する。このように本発明の光触媒材料は、活性酸素種であるスーパーオキサイドアニオンを生成しないという安全面での利点もある。
酸化チタン(TiO2)粉末(ルチル型、テイカ(株))と酸化セリウム(CeO2、和光純薬工業(株))をモル比0.995:0.005で混合し、1200℃で5時間焼成することによって、セリウムイオンドープ酸化チタンを得た。このセリウムイオンドープ酸化チタンを、紫外線光電子分光法により測定したところ、価電子帯上端電位は3V(vs.SHE,pH=0)であった。また、フラットバンド電位測定により測定したところ、伝導帯下端電位は0.05V(vs.SHE,pH=0)であった。
実施例1と同様にしてセリウムイオンドープ酸化チタンを得た。そしてこのセリウムイオンドープ酸化チタンを、蒸留水に対するTiO2の割合が10質量%となるように、蒸留水中に懸濁させて分散した。次でこれに、FeCl3・2H2O(和光純薬工業(株))を、TiO2に対するFe(III)の割合が0.1質量%となる量で加え、攪拌しながら90℃に加熱して1時間保持した。このようにして得られた懸濁液を吸引濾過によって濾別し、残渣を蒸留水によって洗浄した後に、110℃で加熱乾燥することによって、鉄三価塩を担持したセリウムイオンドープ酸化チタンを、評価用サンプルとして得た。
アナターゼ型酸化チタン(「ST−01」、石原産業(株))を評価用サンプルとして用いた。
アナターゼ型酸化チタン(「ST−01」、石原産業(株))をアンモニア気流中(1SCCM)において、550℃で3時間アニールすることによって、評価用サンプルとなる窒素ドープ酸化チタンを得た。
上記のように実施例1〜2、比較例1〜2で得た評価サンプルについて、光触媒活性を、可視光照射下で2−プロパノール(IPA)が気相酸化分解される結果生じるアセトンおよびCO2濃度を定量することにより評価した。以下に詳細を示す。
図2に実施例1のCu(II)担持セリウムイオンドープ酸化チタンのIPA分解結果を一例として示す。また実施例1〜2および比較例1〜2の評価結果を表1にQEの値で示す。尚、比較例1の「N.D.」は検出限界未満を示す。
