| 研究実績の概要 |
New-type high quality super-porous carbon materials were fabricated from renewable biomass precursors for multi-applications (sensors, energy storage and conversion device applications). (i) One-pot synthesis of the sugarcane baggase-derived carbon decorated with ZnO nanoparticles electrode show extraordinary high selectivity, sensitivity, and detection limit for AA, DA, UA, H2O2, and N2H4 together with excellent supercapacitive performance, surpassing common graphene- or carbon-based electrodes. (ii) The nitrogen-enriched (1.39% of nitrogen naturally) peanut shell-derived graphene-like porous carbon nanosheets (N-GCNs) with unique properties, thus, suitable as a practical platform for supercapacitor and as metal-free catalyst for oxygen reduction reaction (ORR) applications.

理由
Currently, we are doing some interesting multi-disciplinary projects on nitrogen-enriched Fish scale derived carbon as metal free ORR electrocatalyst. In this work, for the first time we achieved 10% of nitrogen without any external doping. In addition, we are focusing to engineer the physical properties of the low cost carbon materials. In particular, tailoring the pore sizes, increasing the surface area and functionalization with inexpensive inorganic nanoparticles and heteroatoms, thus suitable for the electrochemical biosensors and energy applications. In this case, we have been focusing on some different kind of biomass precursors such as plant leaves, etc,. In addition, we are focusing on liquid crystal nanosheet gel as solid state electrolytes for the flexible electronic devices.

| 今後の研究の推進方策 |
The development of next generation efficient energy storage devices which is light, flexible, aesthetic diversity, and small units with shape-conformability, and excellent mechanical properties, with high energy and power characteristics is highly important. We will investigate better conditions for fabrication of lignin-derived carbon fiber composite (CFC) electrode material properties.. Notably, we first sought to introduce biodegradable gel electrolytes (vertically oriented nanosheets); offers several useful properties with high ionic conductivity, modulated thickness, gel can transfer any kind of substrate, green, nontoxic, and cost effective, which is quite important to the next generation flexible electronics with several concerns like inexpensive, safety, with improved capacitance.
