Tailoring of Novel Amorphous RuS2/ZrS2/MWCNT Nanocomposite Platform as a Dual Sensor for the Detection for Water Pollutant Indigo Carmine

The present study focuses on synthesizing amorphous nanocomposites of RuS 2 /ZrS 2 /MWCNT and exploring their potential for modifying electrodes and detecting indigo carmine dyestuff. Amorphous materials have recently garnered significant attention due to their ability to control material properties through their distinct nature. Transition metal dichalcogenides, or TMDs, are being extensively used in various applications such as catalysis, dye degradation, and so on. Amorphous transition metal sulphides, due to their heightened active sites, exhibit higher performance. This study presents the first-ever successful production of two amorphous metal sulphides that are doped with multi-walled carbon nanotubes. The resulting novel material was used to detect indigo carmine with high efficiency. The detection range was wide, spanning from 0.1 μM to 300.0 μM, and the limit of detection was 0.08 μM. These results demonstrate that the material outperforms most previously reported studies in this field. The technique employed was both simple and innovative, and it was used on both Glassy Carbon Electrode (GCE) and Screen-Printed Electrode (SPE) systems. It was effectively evaluated for the detection of the dye in water samples as well as food and pharmaceutical samples.
