Abstract

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.

期刊介绍： Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
