General Description
4-Nitro-3-pyrazolecarboxylic acid is a pyrazole derivative. Catalytic activity of bimetallic colloids, composed of silver nanoparticles partially coated with Pd clusters, adsorbed on 4-nitro-3-pyrazolecarboxylic acid, has been investigated by Surface-enhanced Raman scattering (SERS) spectroscopy. Effects of this pyrrazole on blood flow and its palladium hydrogenation has been studied.
