ABSTRACT
In the present study, we have demonstrated the usage of metal/metal oxide nanoparticles (NPs) synthesized by solution combustion using aluminum oxide (Al2O3) and tin dioxide (SnO2) NPs along with green approach using leaf extract of Simarouba glauca (SG) and aerial extract of Celastrus paniculatus (CP) as they have well-known ethno-pharmaceutical properties. The prepared Al2O3, SnO2, green synthesized Ag, and CuO NPs formations were confirmed by UV-Vis spectrophotometry and further characterized to study their size, structure, functional groups, morphology, and surface area by XRD, FTIR, SEM-EDX, TEM, and BET analysis. The phytonutrients present in medicinal plants aided as capping and stabilizing agents for Ag and CuO NPs and reduced the particles to 30–45 nm size. Additionally, this mechanism was also observed using FTIR by their transmittance values. Meanwhile, the chemically synthesized NPs were of the particle size 20–35 nm and had acquired good absorption of nitrogen gas onto their surfaces.
