Abstract

AbstractIn this study, silver nanoparticles‐doped graphene oxide (AgNPs@GO) nanocomposite was green synthesized using the extract of Curcuma longa as an effective reducing and stabilizing agent.. Characterization of AgNPs and AgNPs@GO were thoroughly examined via several analysis methods. Thereby, the results show the successful formation as well as the uniform distribution of spherical nano‐sized silver fragments on the GO surface with an average size of 21.14 3.21 nm. The materials were then tested regarding their optical sensing for H2O2 and Hg2+. In specific, AgNPs@GO indicated a great colorimetric detection towards H2O2 and Hg2+ with a remarkably low detection limit at 0.48 and 0.158 μM, respectively. Conclusively, AgNPs@GO nanocomposite poses a high potential in application sectors of the colorimetric sensor.
