Spectrophotometric evaluation of surface morphology dependent catalytic activity of biosynthesized silver and gold nanoparticles using UV-vis spectra: A comparative kinetic study

- The biosynthesized silver nanoparticles were stable for 6 months and used as effective SERS active substrate.
- They are effective catalyst in the chemical reduction of 4-nitrophenol to 4-aminophenol.
- Comparative catalytic efficiency of both silver and gold nanoparticles was studied spectrophotometrically.
- Our results demonstrate surface morphology dependent catalytic activity of both nanoparticles.
