Abstract

ABSTRACT

The development of efficient and sustainable photocatalysts to purify wastewater is a major thing in the cleaning of the environment. The synthesis process of a vanadium molybdate/graphitic-carbon nitrate nanocomposite (V₂MoO₈/g-C₃N₄) by employing low-cost and simple, eco-friendly co-precipitation method. The nanocomposite was prepared to enhance the work of the solar-light-driven photocatalytic catalyst in the degradation of organic dye pollutants such as methyl orange (MO) in aqueous conditions. Structural and morphological, functional group analysis is proved the creation of a heterojunction between V₂MoO₈/g-C₃N₄, which allows a further division of charges and reduction of the fusion of electrons and holes. The degradation efficiency of the nanocomposite was very high compared to the single nanomaterial due to the synergistic effect of the elements of the nanocomposite and the capacity to absorb better light. The low amount of catalyst used and the initial dye concentration and the duration of irradiation were also investigated in a systematic manner. Additionally, the nanocomposite was also observed to be very stable and reusable even after a series of cycles, an indication of practical usability. This work provides a sustainable approach to designing effective photocatalysts by using low-cost materials and gentle conditions in the fabrication process. This increased photocatalytic activity and environmental support of the vanadium molybdate/g-C₃N₄ nanocomposite have made it a suitable material in wastewater treatment and environmental protection.
