In this present communication, we have synthesized the Bi2S3-xC dots (x = 0, 0.03, 0.06, 0.13, 0.27, 0.67 and 1.0) nanocomposite samples by using low temperature hydrothermal method. The XRD measurements confirmed the phase purity and nanocomposite nature of the synthesized samples. FESEM and TEM measurements confirmed that, Bi2S3 samples have rod shape of morphology and their sizes (diameter) are between 15-30 nm in pristine Bi2S3 and Bi2S3-xC dots samples allografted with amorphous C dots. The photocatalytic properties of the Bi2S3-xC dots nanocomposite samples against the ciprofloxacin (CIP) antibiotic were studied in detail. The maximum photocatalytic activity was shown by x = 0.67 sample (maximum 88% CIP degradation, in 80 min) due to effective electrons transfer and reduction of charge recombination rate in the p–n junction, formed between the nanocomposite. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.
