Fabrication of 2D Rod Like Structure MoO₃ Anchored on 2D Nitrogen Rich Sheet g-C₃N₅ for Improvised in Visible Light Absorption for Boosting Photocatalytic Degradation of Doxycycline

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 applications.
