The synthesized silver nanoparticles were characterized by TEM, FT-IR and uv-vis spectra. The image of transmission electron microscope shows that German silver nanoparticles are highly dispersed in aqueous solution (chapter 4A, ESIw). The average size of silver telluride nanoparticles is about 65438 00 nm (Figure S4c, ESIw), which is a measure of photon correlation spectrum (PCS). Click the infrared spectrum identification product of cycloaddition reaction caused by the reaction of silver nanoparticles with polypropylene of ethyl 2-azido acetate (figure 1a). Figure. In 1b, it is clear that silver nanoparticles of polypropylene have been obtained.

The peak of terminal alkynes is 2 133cm 1. As shown in the figure. Integrated circuit,

Infrared spectra of silver nanoparticles show overlapping peaks.
