研究の背景 Background


Carbon materials have extensively applied in various industrial fields (e.g. anode materials and catalyst supports), because of high electric conductivity, unique mechanical property, high porosity and thermal/chemical stability. The basic properties of carbon materials, such as surface chemical structure and pore structure, greatly affect the function and performance in applications. However, carbon materials generally possess complicated nanostructures, and their understanding and control are limited.

研究の目標 Outcome

炭素材料構造をナノレベルで理解・制御し、これをベースとした新規機能性材料の開発を目指しています。これまでに、炭素材料の表面特性・導電性を活かした、ナノ複合型触媒の開発を行ってきました(Fig.1, 2)。今後は、新規キャラクタリゼーション手法の確立により炭素材料のさらなる理解を深めるとともに、高次制御された新規材料を設計・合成し、触媒・電池といった機能性デバイスへの応用を目標としています。

This research aims to develop a new type of functional materials based on understanding and controlling the nanostructure of carbon materials. Recently, nanocomposite catalysts with carbon materials have been fabricated as shown in Fig. 1, 2. The goal of the study is the establishment of a new characterization technique to deepen understanding of carbon materials, and the controlled-synthesis of functional materials for various applications, such as catalysts and batteries.
