| 研究実績の概要 |
GQDs decorated on hollow porous g-C3N4 were successfully synthesized and characterized by XRD, FT-IR, BET, XPS, Pl, SEM, TEM and mapping analysis. The as-prepared metal-free nanocomposite shows an outstanding photocatalytic activity for the detoxification of paraquat under visible light irradiation. The degradation intermediates were confirmed by LC-MS analysis and the pathways were identified. This results are well supported to the energy-resolved distribution of electron traps using reversed double-beam photoacoustic spectroscopy.

理由
According to the proposed research plan, we are synthesized hollow porous g-C3N4 with GQDs composite and utilized for the degradation of pesticide pollutants, paraquat. Further, we synthesized metal-free clay supported hollow porous g-C3N4-polypyrrole and it will be characterized by DRS-UV, XPS, XRD, BET, TEM-EDX, Impedance, photocurrent and PL etc. The photocatalytic efficacy on metronidazole will be evaluated under visible light and the results will be monitored by UV-VIS, HPLC and LC-MS.

| 今後の研究の推進方策 |
To synthesize metal-free clay supported GQDs on hollow porous g-C3N4-grafted conducting polymers (polyaniline, poly(o-touidine) and poly(o-anisidine)) and it will be characterized by various analytical techniques. The photocatalytic efficacy on pesticides (imidacloprid) and pharmaceuticals (tetracycline and ciprofloxacin) wastewater effluents will be evaluated under visible light and the results will be monitored by UV-VIS, HPLC and LC-MS. Further, the photocatalytic influencing parameters, degradation intermediates and reaction pathways under process. Finally, we will prepare the manuscript and submit to the Journal.
