Iodine-doped carbon dots as a nanocatalyst for degradation of cationic dyes

Water pollution caused by industrial dyes or effluents has grown to be a serious global issue, especially in developing nations. Treatment of these environmental pollutants is essential because they pose a major threat to ecosystems, human health, and biodiversity all over the world. It has been found that using nanoparticles can be an effective way to purify water because of their low cost of manufacturing and environmentally friendly synthesis. Researchers are interested in carbon dots (CDs) because of their special qualities, which include minimal toxicity, excellent electron-donating capacity, high water solubility, and ease of manufacture. To facilitate the Fenton-like degradation of environmental pollutants in water, including methylene blue (MB) and rhodamine-B (Rh-B) dye, we synthesized iodine-doped clove buds-derived carbon dots (I-CCDs). Multiple spectroscopic techniques have been employed to confirm the creation of I-CCDs. I-CCDs are proven to have exceptional antibacterial, optical, and cytocompatibility properties. Using NaBH4 as a reducing agent, it was discovered that the synthesized CDs are an efficient catalyst for the reduction of MB and Rh-B. UV-visible spectroscopy was utilized to create a comprehensive, step-by-step dye reduction method. As-prepared I-CCDs may prove to be a useful addition to systems for treating or purifying wastewater.
