A novel and efficient method has been developed for synthesizing the g-C3N4@CR composite using a simple mingling and heating technique. This method involves the decoration of one-dimensional carmine (CR) onto graphitic carbon nitride (g-C3N4). The light-harvesting composites produced through this process underwent characterization using various spectroscopic techniques, including UV, XRD, FT-IR, Raman, and XPS spectroscopy. To assess the photocatalytic activity of the g-C3N4@CR Composite, its degradation efficiency was investigated by examining its performance in degrading fast green and nitrophenol dyes under outdoor solar light irradiation. The mechanism of degradation for these dyes by the newly designed g-C3N4@CR composite was elucidated through degradation kinetics analysis, involving the determination of parameters such as half-life time, rate constant, and degradation efficiency.
