Article Synopsis
- This article explores how the catalytic activity of silver nanoparticles varies with the size of silica supports, focusing on nanoparticles that are 4 nm in diameter and silica spheres of different sizes (40, 78, 105 nm).
- The study finds that smaller silica supports (around 40 nm) enhance the catalytic activity of silver nanoparticles when reducing Rhodamine 6G using NaBH4.
- Analysis of UV-vis spectra indicates that the size and shape of the silver nanoparticles remain stable during the catalytic process, suggesting minimal loss of catalytic activity.
