After the reaction, the absorption peaks at the wavenumbers of 3420 cm-1, 1621 cm-1 and 1401 cm-1 in the infrared spectrum of PdNPs were significantly weakened before and after the reaction.
After the reaction is completed, the absorption peaks of 3420 cm-1, 1621 cm-1 and 1401 cm-1 in the PdNPs infrared spectra decrease significantly before and after the reaction.
