Phytoremediation is a promising, cost-effective and eco-friendly approach in the treatment of polluted wastewater and industrial waste effluents. The aim of the study is to understand the potential effects of Catharanthus roseus leaf extract mediated stannous oxide nanoparticles (SnO) formation and its efficiency of dye degradation was investigated. The C. roseus was used for the first time as a reducing agent in the formation of SnO nanoparticles. The secondary metabolites present in plants were evaluated by GC-MS and its bioactive compounds are identified. The synthesized SnO nanoparticles were confirmed and supported by XRD, FTIR, Zeta, DLS, SEM with EDX and TEM with SAED pattern analysis. Photocatalytic activity of SnO nanoparticles efficiency and its synergetic effects against dye degradation was estimated. Thus, C. roseus acts as a reducing agent in the formation of SnO nanoparticles and also helps in maintaining stability. Also, it is an eco-friendly approach with the effect of time in process of dye degradation.
