Biosynthesis of Ag Nanoparticles Using Caralluma acutangula Extract and Its Catalytic Functionality towards Degradation of Hazardous Dye Pollutants

Nanomaterials, today, are an integral part of our everyday lives, industrial processes and appliances. Biosynthesis, because its environmental sustainability, is now becoming a hot topic. The biosynthesis nanomaterials using plant phytochemicals enhances the nanomaterial’s biocompatibility compatibility with environment too. Hence, forthe first time, this study uses Caralluma acutangula (CA) extracts to synthesize silver nanoparticles (CA-AgNPs) characterize them UV–visible spectroscopy, FTIR, Raman XRD, TEM, TGA, SEM, EDX, zeta potential, bandgap analysis. particle size distributions CA-AgNPs were observed fall in range 2–6 nm predominantly TEM images. High crystallinity % was calculated as 86.01 XRD data. Extracted from CA characterized analyzed GC-MS. (Eg) 3.01 eV potential found be ?16.1 mV. biosynthesized confirmed for their degradation efficiency two toxic water pollutant dyes: Congo red, CR (95.24% within 36 min), methylene blue, MB (96.72% 32 presence NaBH4.
