Hydrothermal synthesis of gold nanoparticles using spider cobweb as novel biomaterial: Application to photocatalytic

In the present study, we have followed the hydrothermal path for the synthesis of gold nanoparticles (Au NPs) from the novel biomaterial spider cobweb, which is a rapid & non-chemical way. The synthesized nanoparticles were thoroughly characterized by XRD, UV-vis, SEM, EDAX and TEM studies used for the photocatalytic dye degradation studies. Here we have used two dyes namely Rh B and MB, Au NPs has shown the good photocatalytic activity, this is due to more sensitive to light and reduces the electron-hole recombination.
