A Sustainable Nanocomposite Au(Salen)@CC for Catalytic Degradation of Eosin Y and Chromotrope 2R Dyes.

ABSTRACT: Up to now, a very few catalysts have been developed approaching the heterogeneous catalytic degradation of Eosin Y and Chromotrope 2R dyes (Acid Red 29). The present study provides a complete perspective of recyclable nanocomposite Au(Salen)@CC for catalytic degradation of hazardous water pollutant dyes viz., Eosin Y & Chromotrope 2R using mild reaction conditions. New gold Salen complex doped carbon nanocomposite Au(Salen)@CC was developed by easy methodology using nano carbon cage (CC) prepared from low-priced Pyrolysis fuel oil (PFO) residue based Pitch. The UV-Vis adsorption spectroscopy results of Eosin Y and Chromotrope 2R dyes indicated complete degradation into acidic compounds which can be further mineralized to CO₂ and H₂O under mild reaction conditions. The heterogeneous catalyst recycled and reused successfully for four repeated experiments without loss in its adequate performance. This new sustainable and eco-friendly catalyst delivered significant degradation activity compared to existing reports and it can be further utilized for new multifunctional applications such as, radiopharmaceutical activities, heterogeneous catalysis and chiral resolution.
