Research

金属やその化合物のナノ構造体はその新奇な特性から大きな注目を集めています。私たちは「これまでに作製されていない」ナノ構造材料の合成にチャレンジしています。例えばこれまでに、形状や配列を高度に制御した金属ナノ粒子や金属酸化物ナノ構造体の作製に成功しました。これは特異的な光触媒作用を示すことや、配列の周期性を高めることで、超薄膜偏光子への応用も可能であることを明らかとしました。合成に成功した材料の応用範囲は光触媒や光学素子に限らず、太陽電池やメモリ材料など多岐にわたっています。

Theme1:Liquid synthesis of noble metal nanoparticle-containing materials with highly ordered nanostructures and the optical and photocatalytic properties

Overview
1

Noble metal nanoparticle-deposited mesoporous metal oxides are synthesized. The well-aligned and shape-controlled nanoparticles in the mesochannels exhibit unique optical and photocatalytic properties. Solar water splitting for hydrogen generation is one of the main research topics recently.

Theme2:Fabrication of AgX nanoparticle-containing inorganic-organic hybrid materials and their application to hologram materials

Overview
2

AgX nanoparticle-containing inorganic-organic hybrid materials are fabricated via the sol-gel route. The materials show unique reversible photo-responses thus the application of them to hologram materials is being examined.
