Abstract

金ナノ粒子を導電体基板表面に修飾すると,通常,導電体基板単独の場合とは異なる電気化学特性が発現する.特に,金をナノ化することで発現するバルクとは異なる電気化学特性や触媒特性を有効に利用すると,新しいタイプの修飾電極の構築が可能になり,電気化学分析の進展にも寄与できる.著者らのグループでは,2001年頃から,金ナノ粒子を修飾した酸化インジウムスズ電極の構築と応用を中心に,これまで検討を進めてきた.本総合論文では,著者らの2010年以降の金ナノ粒子修飾電極に関する研究の展開について,電気化学以外の共同研究成果や白金ナノ粒子に関する検討結果なども含めて概要をまとめる.特に,新たな研究の展開としては,金ナノ粒子とパラジウム基板電極の複合化や,キムワイプ片などの非導電性保持材料を用いた金ナノ粒子または白金ナノ粒子の電極界面の三次元的修飾などについて述べる.

The modification of gold nanoparticles on the surfaces of conducting materials usually develops interesting electrochemical properties that are different from those of conducting materials. Especially, unique electrochemical and catalytic properties of nanostructured gold, which are not available in the bulk state, permit the construction of novel modified electrodes, while realizing some significant contributions to electroanalytical chemistry. Our group has been studying the fabrications and applications of gold nanoparticles-modified indium tin oxide electrodes since 2001. In this account, I introduce some developments of our research on gold-nanoparticle-modified electrodes after 2010, including some achievements in collaborative research as well as research results obtained using platinum nanoparticles. As relatively new topics, the combination of gold nanoparticles with a palladium base electrode and the utilization of non-conducting supporting materials for modifying the vicinity of the electrode surface with gold nanoparticles are described.
