Description
サンプル製造に用いるため、直径25mm×厚さ3mmのマグネシウムマグネトロンスパッタリングターゲット(Mg、純度>99.95%)及びパラジウムマグネトロンスパッタリングターゲット(Pd、純度>99.95%)をKurt J. Lesker(PA、USA)から購入した。高純度のメタノール、アセトン、イソプロパノールをシグマ アルドリッチ ジャパンから購入した。
AFM及びXPS測定用の基板として、(100)配向性及び5mm×5mmのサイズを有するアンドープのSiダイスをMTI Corporation(CA、USA)から購入した。TEM/STEM−HAADF解析用の基板として、電子透過炭素被覆グリッド(400メッシュ)を有するCuフレーム及び窒化シリコン膜をTed Pella Inc.(CA、USA)から購入した。
ブルカー社のMultimode 8原子間力顕微鏡(AFM)を用いて、サンプルのトポグラフィーを解析した。NanoScope(登録商標)Vコントローラを備えるAFMシステムを、三角形窒化シリコンAFM探針(半径<10nm、力定数0.35N/m、共振周波数65kHz)を用いてタッピングモードで利用した。
<ガラス状炭素電極基板上のナノ粒子触媒の調製>
上述したMantis UHVナノ粒子スパッタリングシステム内で、ナノ粒子を電極表面上に直接堆積させた。ナノ粒子寸法及び表面被覆率はTEM画像を用いて評価し、関連質量はバルク密度値を仮定して計算した。触媒の荷重は、Pdサンプルは0.085μgと推定し、Pdコア−MgOシェルサンプルは0.034μgと推定した。
室温で、electrochemical workstation 440B(CH Instruments Co.、US)を用いて、電極触媒作用測定を行った。作用電極としてのナノ粒子改質ガラス状炭素(GC)電極、対電極としてのPtワイヤ、及び参照電極としてのAg/AgCl(3モルのKCl)電極からなる従来の3電極システムを用いた。全ての希釈標準溶液(1モルのKOH)を計測前に30分間窒素で洗浄した。
本発明の実施形態に係る合成サンプル、すなわち、Pdコア−MgOシェルナノ触媒の構造を図2に示す。図2は、本発明の実施形態に係る製造されたPdコア−MgOシェルナノ粒子の評価した構造を示す。(a)はコア−シェルモルフォロジーを示すPdコア−MgOシェルナノ粒子の低倍率TEM概観である。(b)は、コア(Pd)領域のHRTEM画像であり、(c)は、シェル(MgO)領域のHRTEM画像である。(b)及び(c)における挿入図は、それぞれ、対応するHRTEM画像のシミュレーション画像である。(d)は、Pdコア−MgOシェルナノ粒子のコア−シェルのHAADF−STEM画像である。(e)は、((d)における線に沿った)STEM−EDSを用いたライン走査によって得られたPdコア−MgOシェルナノ粒子におけるMg成分及びPd成分の分布である。
