Fabrication of 2D rod like structure MoO 3 anchored on 2D nitrogen rich sheet g-C 3 N 5 for improvised in visible light absorption for boosting photocatalytic degradation of Doxycycline

Abstract A novel MoO3@g-C3N5 was prepared by using hydrothermal method followed by ultrasonication ecological remediation. The materials were confirmed by using several analytical techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET), UV–vis diffuse reflection spectroscopy (UV–vis DRS) and photoluminescence (PL) spectroscopy. The photocatalytic performance of the MoO3@g-C3N5 samples was evaluated by measuring the degradation of Doxycycline (DOX) under visible light irradiation. The experimental studies confirm that the nanocomposite MoO3@g-C3N5 (10 wt.%) exhibits enhanced photocatalytic activity by the optimized percentage of g-C3N5 which increases the light harvesting ability as well as fast electron transfer and efficient charge separation. Therefore 94.4% breakdown efficiency of Doxycycline (DOX) was achieved with 70 min. Meanwhile, the scavenger experiment shows that •OH radical plays a predominate role in the degradation process. Even after five consequent cycles the catalyst exhibit excellent photocatalytic degradation. MoO3@g-C3N5nanocomposite exhibited good results, indicating that it might be an efficient photocatalytic material for environmental application.
