    　View Summary

    Micropores smaller than 1 nm in carbon materials have garnered significant attention for their ability to induce confinement effects. Anomalous improvements in the specific capacitance and reversibility of electrochemical redox reactions have been reported. However, due to limitations in synthetic methods, carbon materials with identical physical properties but varying pore sizes have not yet been successfully prepared. In this study, we investigate the relationship between the pore size of carbon materials and reversibility of the redox reaction of quinone-based molecules using reduced graphite oxide (rGO) as a model electrode material. Cross-linked GO and rGO exhibit minimal changes in surface properties while allowing precise tuning of the interlayer distance at the Ångström level. The Δ E p values of the redox reaction of quinone-based molecules on cross-linked rGO decrease with decreasing interlayer distance. These findings strongly indicate that the reversibility of the redox reaction can be enhanced by reducing the pore size of carbon materials. This study clearly demonstrates the origin of the relationship between pore size and reversibility of the redox reactions of quinone-based molecules.

    　View Summary

    <p>In energy storage and conversion applications, high performance can be achieved by maximizing nanomaterial utilization—ideally approaching 100 %. This study comprehensively investigates the preparation of layered nanomaterials and the effects of nanoconfinement on the performance of energy storage and conversion devices. Specifically, K<i><sub>y</sub></i>IrO<i><sub>x</sub></i> and K<i><sub>y</sub></i>PtO<i><sub>x</sub></i> layered materials were successfully synthesized via solid-state reactions, thereby expanding the library of oxide-layered compounds. Additionally, a free-standing nanosheet structure (2.5D) was fabricated using a macroporous carbon template. Quinone-based aromatic compounds were adsorbed into activated carbon micropores smaller than 1 nm, yielding an adsorption-controlled system. A model electrode study employing reduced graphite oxide demonstrated that the redox reversibility of redox-active aromatic compounds was improved with decreasing interlayer distance. This finding suggests that the redox reversibility can be tuned effectively by controlling the nanoscale spacing in electrode materials.</p>

  • Synthesis of three-dimensional architecture composed of two-dimensional nanowalls

    Grant-in-Aid for Early-Career Scientists

    Project Year: 2018.04  -  2020.03 

    Investigator(s): Takimoto Daisuke 

    Direct: 2,300,000 (YEN)  Overheads: 2,990,000 (YEN)  Total: 690,000 (YEN)

    　View Summary

    In this study, a new electrocatalyst with a three-dimensional architecture composed of a framework of NiO nanowalls was prepared. The electrocatalytic activity of three-dimensional architecture was higher than that of nanoparticles. The result strongly indicates that the 3D structure with 2D nanowall is a superior design for electrocatalyst. Considering the diffusion path of evolved molecules, the enhanced activity could also be attributed to the meso pore nature of 3D-NiO.
