Bismuth Molybdate Supported on Graphitic Carbon Nitride Nanocomposite for Solar Driven Photodegradation with Enhancing Antibacterial and Antifungal Applications

Abstract

In this investigation, Graphitic carbon nitride wrapped bismuth molybdate nanocomposite has been synthesized efficiently to degrade the organic pollutants in water through the photodegradation process and to study their antibacterial and antifungal activities. Nanomaterials have been synthesized via hydrothermal method and antibacterial and antifungal properties are predicted using the disc diffusion method. The characterization of the synthesized materials viz., Bismuth molybdate and Graphitic carbon nitride loaded Bismuth molybdate nanomaterials were carried out using various techniques like X-ray diffraction, Field-emission Scanning electron microscopy and Energy dispersive X-ray, Transmission microscopy, X-ray photoelectron spectroscopy and ultraviolet spectroscopy. The photocatalytic performance of the samples under visible light was evaluated by observing the photodegradation of dye molecules. When compared to pure bismuth molybdate the loaded nanocomposite showed improved photocatalytic efficiency. Particularly, nanocomposite containing graphitic carbon nitride displayed the highest photocatalytic activity. Incorporating carbon nitride results in improved absorption of visible light and reduced recombination rates of photo-generated charge carriers. Furthermore, the prepared g-C₃N₄/Bi₂(MoO₄)₃ exhibited significant antibacterial and antifungal activities against four bacterial and two fungal strains. The developed method for preparing g-C₃N₄-based photocatalyst offers an encouraging approach to environmental remediation due to its convenience and cost-effectiveness. Moreover, the current research offers a novel nano-drug alternative.
