| Outline of Annual Research Achievements |
Using a solution based strategy under an ambient conditions of temperature and pressure, we have successfully produced fullerene-based nanomaterials including macaroni fullerene crystals and hexagon sheets which upon thermal annealing transformed into hierarchically porous carbon materials consisting of both micro-and mesopore architectures. The obtained porous materials have been characterized by FTIR, Raman scattering, XRD, SEM, TEM and XPS. It is concluded that the surface area and porosity of the fullerene based materials could be enhanced upon thermal annealing at higher temperatures. Preliminary results show that the porous fullerene nanomaterials show better selectivity towards aromatic vapors such as benzene, toluene and aniline compared to aliphatic vapors.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The research is progressing a bit slower than expected, which is partly due to COVID19 pandemic. Also, due to batch synthesis technique, scale up material production is taking time. We are also thinking of alternative ways to scale up keeping the porous structure of the materials.

| Strategy for Future Research Activity |
Fabrication of novel composite materials based on fullerene-derived nanoporous carbon and deep and detailed investigations of the VOC sensing performance covering a wide varieties of analyte vapors such as alcohols, aldehydes, acids, and aromatic compounds.
