高活性なアンモニア合成触媒を実現 -アンモニア合成の新技術として期待-
2012/10/22
Languages： Japanese
窒素と水素の反応によって合成されるアンモニアは、人類が最も多く生産する化学薬品であり、その生産量は年間1.7億トンを越える勢いになっており、さらに増え続けています。アンモニアは肥料原料として社会を支えてきただけではなく、近年では燃料電池等のエネルギー源として期待が高まっています。約100年前に確立された触媒によるアンモニア製造技術は高温・高圧のプロセスが必要であり、多エネルギー消費型のプロセスです。アンモニア生産時の消費エネルギーを可能な限り低減することは、食糧とエネルギーに大きく貢献することが期待されていました。このような背景の中、東京工業大学応用セラミックス研究所の細野秀雄教授、原亨和教授のグループは、セメントの構成成分の一つである12CaO・7Al2O3(以下C12A7)の構造の中に電子を取り込んだエレクトライドにルテニウムのナノ粒子を固定することで高性能なアンモニア合成触媒…

東京工業大学応用セラミックス研究所の北野政明特任助教（神奈川科学技術アカデミー・原「エコ固体酸触媒」プロジェクト・元常勤研究員），原亨和教授らは，神奈川科学技術アカデミーとの共同研究によって，酸化チタン（チタニア）をナノチューブにすると，熱を加えなくても高効率の革新的な触媒として機能することを発見しました。チタニアナノチューブ（用語1）は簡単，安価に合成でき，室温で実用レベルの触媒機能を発揮するため，100度Ｃ程度に加熱が必要な従来の触媒を使った場合に比べ，化学反応のエネルギー効率が3倍以上に向上。このため燃料や樹脂，医薬品，洗剤などの化学品生産に要するエネルギーと地球温暖化の原因である二酸化炭素（ＣＯ2）排出量が1／3以下に低減できます。さらに，酸化チタンは資源量が豊富で安価に入手できるため，コスト削減効果も期待できます。

Two-dimensional metal oxide sheets in cation-exchangeable layered metal oxides such as HTiNbO_5 and HNb_3O_8 were examined as solid-acid catalysts. Exfoliation of HTiNbO_5 and HNb_3O_8 in aqueous solutions formed colloidal single-crystal TiNbO_5 and Nb_3O_8 nanosheets, precipitating under an acidic condition to form aggregates of the nanosheets. Although esterification of acetic acid, cracking of cumene and dehydration of 2-propanol were not catalyzed by original layered metal oxides because of the narrow interlayer distance, which prevents the insertion of organic molecules, the nanosheet aggregates functioned as strong solid acid catalysts for the reactions. NH_3 temperature-programmed desorption and ^1H magic-angle spinning nuclear magnetic resonance spectroscopy revealed that these nanosheet aggregates have strong Bronsted acid sites due to Nb^<5+> (or Ti^<4+>)-(OH)-Nb^<5+>.
We also found that amorphous carbon composed of small graphen sheets with high density of sulfonic acid groups function as a replacement for sulfuric acid catalyst. The material prepared from inexpensive starting materials has high thermal and chemical stability. -

本研究はカチオン交換性層状金属酸化物から得られる厚さ数nm未満のポリアニオンナノシートを高性能な光触媒、固体酸触媒、部分酸化触媒、あるいは新材料として展開することを念頭に置き、光触媒反応、酸触媒反応、部分酸化反応に最適な2次元マクロポリアニオンシートの探索を行うと同時に、ポリアニオンシートの構造を解明することを目的としている。
十数種類のカチオン交換性層状金属酸化物の単結晶ポリアニオンナノシートを液相で剥離し、これを凝集させることによって得た高表面積の粉末材料を触媒として様々な反応が研究された。HTiNbO_5、HTi_2NbO_7、及びH_<1.15>Ti_<1.15>Nb_<0.85>O_5ナノシート凝集体はエステル化等の液相酸触媒反応において非常に強い固体酸触媒として働くことが既に明らかになっているが、これらはエポキシ化等の部分酸化反応に対しても非常に高い触媒活性をもつことがはじめて見出された。
従来の手法、及び分光学的手法によってこれらのシート凝集体の部分酸化触媒能はNb^<5+>に起因することが確認された。Nb^<5+>が部分酸化触媒反応で高活性な活性点として働くことはこれまで知られておらず、上記の材料は全く新しいタイプの部分酸化触媒といえる。
以上の結果はポリアニオンナノシートが固体酸触媒として機能するだけでなく、部分酸化触媒として応用展開できることを示している。 -

これまでの研究から、数多くの単純な金属酸化物の中でNiO、Co_3O_4、Cu_2O、Fe_3O_4、RuO_2、IrO_2のみがメカノキャタリシスによる水の全分解反応の触媒となることが明らかになった。同じ反応条件ではでNiO、Co_3O_4が高い触媒活性を示す一方、RuO_2、IrO_2は低活性であった。この触媒反応は前述のように反応容器底面とその上で回転する回転体の間に挟まれた触媒粒子に力学的エネルギーが加えられて進行するが、その水の分解活性は触媒の粒径、回転体の形状、回転体と反応容器底面の間にかかる圧力に大きく依存した。触媒粒経がサブミクロンオーダーの場合、反応容器底面と回転する攪拌子の間にある小さな触媒粒子に充分な力学的エネルギーが与えられないために水分解活性は非常に小さい。平らな反応容器底面に回転体を線接触した時の活性は面接触の場合より高く、回転体を反応容器底面に押し付ける力に比例して水の分解速度が大きくなった。これらの結果は触媒粒子に加えられる圧力が高いほど触媒に与えられる力学的エネルギーが大きくなり、水の全分解速度が速くなることを示している。各々の反応条件下、これらの金属酸化物触媒の中でNiOが最も高い水の分解活性をもち、力学的エネルギーの変換効率は4-10%に達した。一方、RuO_2、IrO_2は最適条件下においても低い活性しか示さなかった。
また、NiO、Co_3O_4、Cu_2Oを用いて反応メカニズムの解明が試みた結果、反応条件下でこれらの金属酸化物表面の一部は金属まで還元され、再び元の酸化物に戻ることが明らかになった。このことは触媒表面でレドックス反応が進行していることを示している。分光学的な解析も行われ、水がない状態でCu_2Oに力学的エネルギーを回転体によって与えると波長600nm未満(>2.1eV)の発光が検出された。Cu_2Oのバンドギャップエネルギーが2.1eVであることを考慮すると、力学的エネルギーを与えられたCu_2Oでは電子のバンドギャップ遷移が起きていることが考えられる。他の触媒の分光学的実験は現在継続中であるが、Cu_2Oのメカノキャタリシスでは力学的エネルギーがバンドギャップ遷移を起し、これが触媒表面でのレドックス反応のドライビングフォースとなっていることが予想された。 -
層状金属酸化物と用いた新規光機能性薄膜の創出

本研究で用いる薄膜の評価はバルク構造、表面構造、電子構造、物性等から行い、層状金属酸化物薄膜の新機能の発現を探るだけでなく、これまでわかっていない層間現象の解明を試みてた。ウロコ鉄鋼型Ti系層状金属酸化物Cs_xTi_<(2-x/4)>_<x/4>O_4薄膜、及びNb系層状金属酸化物K_4Nb_6O_<17>薄膜は、層構造を維持した状態で金属カチオンなど種々カチオンの層間へのインターカレートを行えることが確認された。また、アルキルアミンにより層間修飾を行うと、層間距離が広がることをXRDにより確認でた。更に、SNO電極上に形成させた薄膜は、同処理を行うことにより電気伝導性の向上を図れることがCVにより示唆された。また、層間距離を広げることにより、有機金属錯体(Ru(bpy)_3^<2+>等)のインターカレートも可能となった。薄膜自体は可視光領域に吸収帯を持っていないが、可視光照射下で光機能性を持つ有機金属錯体を層間にインターカレートした薄膜は、可視域に吸収帯を持たせることができた。現時点で調べた錯体Ru(bpy)_3^<2+>やメチルビオロゲンは、他種カチオンが多量に存在している条件においても層間に固定化させておくことができ、さらには電気化学的手法により可逆的に酸化還元反応を行えることが明らかになった。可視域に吸収を持たせ、さらには層間にインターカレートした錯体を安定にレドックスさせることができるという結果を得たことにより、光機能性薄膜構築に向けて重要な指針が得られた。

光機能性層状酸化物薄膜の創成と物性

本研究では層状金属酸化物をソフトケミカル的手法によって薄膜化し、その物性、構造を評価することによって従来の限界を超えた新規光機能性デバイスの可能性を模索することを目的としている。層状チタン酸の1種であるCs_xTi(2_<-2>/4)□_x/_4O_4のプロトン交換体は、水酸化テトラブチルアンモニウムやエチルアミンの水溶液の中においてチタン酸シートの剥離が可能である。この剥離したシートを基板上にスピンコートすると二次元に配列した層状の薄膜が非常に容易に得られる。この薄膜は層間に有機物であるアミンを含むため熱的安定性に乏しく、それ以上の修飾方法が限定されていたが、水溶液中でイオン交換を行うことにより耐熱性を持たせることに成功した。交換前の薄膜においては、250°C以上の加熱により層間の縮合が起こり、そのイオン交換能が失われる。しかしながら薄膜をCsCl水溶液中で処理することで、層間のアミンがCsイオンに置き換わり、この薄膜は450°Cの加熱後においても層構造を失うことなく、安定であることが確認された。またCs以外にも多種のイオンへの交換が可能であることが確認され、特にNi等においては層間において還元が可能であり、チタン酸シートとNi微粒子を交互に包括した薄膜が得られた。
層状ニオブ酸K_4Nb_6O_<17>はその層間が容易に水和するため、湿式粉砕を行うと超微粒子を含む懸濁液が得られ、この懸濁液を基板上にスピンコートし高温で焼成すると結晶成長が起こり、非常に結晶性の良い層状の薄膜が得られる。この薄膜は前者に比較して結晶性、熱安定性の両者で勝っており、イオン交換能においても種々の金属イオンを始め錯体のインターカレーションも可能であることが分かった。また長鎖のアルキルアミンを層間に挿入することで自由に層間距離が変えられることが確認され、この層間距離を広げた薄膜を前駆体として用いることで、Ru(bpy)_3色素などの大きな分子への交換も可能となった。 -

Photocatalysts recently attract a great attention from the view point of eco-friendliness. However, already found photocatalysts do not avail the visible light which dominates the solar light. Although several materials such as CdS were found to utilize the visible light, the eco-harm nature of them is the great disadvantage. We have found that the ion-exchangeable transition metal oxides are promising catalysts which have the photoresponse in visible light region. The serious problem of those materials are that their high interlayr electron density inhibit the intercalation of reactants and that the interlayr spase has not been efficiently utilized. On the other hand, the use of intercalation of organic ions such as tri-butyl-ammonium ion (TBA+) enabled the exfoliation of the layr to produce macropolyanion sheets highly dispersed in water. Furthermore, the dispersed two dimensional inorganic sheets were found to be starting materials of microporous materials and inorganic thin films. These novel materials demonstrated higher photoactivity than the original transition metal oxide and showed different chemical nature. The new types of layred materials were synthesized and are expected to be utilized as functional materials.
