Abstract
Description
以下の用語は、以下の実施例において用いられ、別記しない限り、以下に示す意味を有する。
OSC=[酸素下における質量−水素・窒素下における質量]/[32×酸素貯蔵物質の質量]
酸化セリウム触媒コアを有する一連の酸素貯蔵物質が、異なる濃度を有する三種類の被覆前駆体と共に、酸化ジルコニウムシェルを形成するために準備された。前駆体には、ジルコニウムブトキシド、ジルコニウムプロポキシド、およびジルコニウム ベンジレート、シグマ−アルドリッチ,ミルウォーキー,WI(Sigma−Aldrich,Milwaukee,WI)、あるいは、アドバンスト,マテリアル,ニューヒル,NC(Advanced Materials,New Hill,NC)から入手できるジルコニウム化合物が含まれる。両方の前駆体は、アルコールをそれぞれの副生成物とする縮合反応によって、酸化ジルコニウムを形成する。表1は、被覆前駆体とその使用濃度を示している。
OSCに対する焼成温度の効果は、酸化セリウムコアおよび酸化ジルコニウムシェルを有する酸素貯蔵物質において、検討される。酸素貯蔵物質は、実施例1において示された方法に従って、9.26グラムのジルコニウム ベンジレート(1−ブタノール中の80質量%溶液)を被覆前駆体として用いて、準備される。OSCおよびBET固有表面積は、測定後、非被覆の酸化セリウムについてのこれらの値と比較される。結果を表2に示す。
コア−シェル形態が網目状の形態により囲まれているコアに変換されている実施例1の物質においても、カプセル状に包まれた酸素貯蔵コアへの酸素の輸送が可能である。
本発明の複合ナノ物質の実現における他の実施例としては、電磁物質がある。ナノ粒子は、それらの小さなサイズが、それらを可視光領域において透明にするが、紫外線(UV)および赤外線(IR)とは強く相互作用することから、重要な光学物質である。複合コア−シェルナノ粒子は、類まれなものである。なぜならば、屈折率や散乱断面積のようなナノ粒子コアの固有の性質が、固有のアプリケーション要件に見合うようにシェルを追加することにより調整されるからである。電磁物質における複合ナノ物質の使用の実現例としては、これらに限定されないが、以下のものを挙げることができる。
複合ナノ物質の実現の他の例としては、化学的に消極的な物質がある。総ての用途は、ユニークな化学的環境を有しているが、いくつかの例においては、ナノ粒子を覆っている層間領域は、化学的に消極的である必要がある。複合コア−シェルナノ粒子は、これらの用途を可能とする。
いくつかの用途は、高価な構成材を必要とする。複合コア−シェルナノ粒子の使用は、存在している物質系において置き換えられることができ、これにより実質的に経済的に有利な物質を作り出すことができる。
