Description
(1)シュウ酸およびシュウ酸の塩を除くカルボン酸またはカルボン酸塩を含む水溶液中で金をアノード酸化し、形成された多孔質膜が安定化される前に該多孔質膜を40℃以下の水に浸漬することを特徴とする金ナノ粒子の製造方法。
純度99.95%の金箔の表面をアルミナペーストで研磨し、これをアノード電極として用いた。金箔保持用基板としてはガラス板を用いた。一方電解液として、0℃、2.5モル/Lのクエン酸水溶液を用意し、対極に炭素板を用い、さらに参照電極としてHg/Hg2SO4(約+0.64V/SHE)を使用して、+4Vの電位(参照電極に対する電圧)を金電極にかけ、アノード酸化を30分間行った。このときの電流密度は約25mAcm-2であった。アノード酸化終了後金電極を取り出したところ、金表面は、オレンジ色の明るい色調であった。アノード酸化により得られた表面皮膜破断面のFE−SEM写真を図1に示す。図1に示すように、厚み約1μmの多孔質膜が均質に形成されていた。
アノード酸化時間を35℃で12時間行うことを除き実施例1と同様に、約25mAcm-2でアノード酸化処理を行った。その結果、表面が黒色であり、金電極との界面がオレンジ色の多孔質膜が得られた。この多孔質を実施例1と同様の条件で純水中に浸漬、静置したところ、実施例1と同様、約30nmの金微粒子が形成された。
2.5モル/Lの乳酸酸水溶液を用いた以外は実施例1と同様にして多孔質膜を作製後、そのまま2.5Mの乳酸酸水溶液中で静置したところ,液が金ナノ粒子の生成を示す赤紫色となった。
