Green Synthesis of SnO2 Nanoparticles loaded on Activated Carbon and its Application as Photocalayst in the Degradation of Alizarin Red S Dye

Abstract

In the present study, hydrothermal method was employed for the synthesis of tin oxide (SnO2 NPs) nanoparticles and was loaded on activated carbon which is obtained from Phaseolus lunatus L. leaves. For the first time the synthesized SnO2-NP-AC was employed as a photocatalyst in the degradation of harmful dye, Alizarin Red S (ARS) from aqueous phase under direct sunlight. A noteworthy increase in the reaction rate was observed due to the maximum migration ability of photoinduced electrons and hindrance in the recombination of the charge–carriers because of electronic interaction between SnO2 NPs and AC.
