  • Surface Structure Effects for Redox Reaction of Molecules Using Carbon Mesosponge†

    Nakasone K.

    Electrochemistry ( 公益社団法人　電気化学会 )  94 ( 5 ) 052006 - 052006   2026.05

    Type of publication: Research paper (scientific journal)

    　View Summary

    <p>Quinone-based molecules provide promising electrode materials for energy-storage devices; however, their redox reaction kinetics are typically slow because the process is governed by mass transfer. The micropore confinement of quinone-based molecules exhibits anomalous pseudocapacitive behavior owing to the characteristic adsorption potentials of micropores. In addition, a highly crystalline carbon surface enhances redox reversibility through strong π-π interactions. This study investigated the effects of surface crystallinity on redox reversibility utilizing a carbon mesosponge comprising single-layer graphene with a crystalline carbon surface. The carbon mesosponge improved the redox reaction despite its mesoporous nature. This result can be attributed to the large amount of adsorbed molecules on the micropore surface and the incorporation of single-layer graphene within the framework.</p>

    　View Summary

    Removal technologies of fluorinated organic compounds have great attentions recently because the compounds are widely used in various industrial products and are persistent in the environment and animals. It is essential to clarify the relationship between the specific surface area and pore size of carbon adsorbent to enhance the adsorption capacity of fluorinated organic compounds. In this study, we found that the interlayer distance of carbon material is key to improve the adsorptive capacity of perfluorohexanesulfonic acid (PFHxS), but the specific surface area had little effect on PFHxS adsorption. Hydrophilicity of the carbon materials also affects the adsorption of PFHxS due to its better dispersion of carbon in aqueous solution.

  • 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.
