Simultaneous Synthesis and Assembly of Gold Nanoparticles in Cuttlebone-Derived Organic Matrix: A "Green" Pathway for Gold Nanocomposite
Abstract:We demonstrate herein a "green" pathway for the formation of a gold nanocomposite using the cuttlebone-derived organic matrix. The gold nanocomposite is achieved through the first exposure of the organic matrix to HAuCl4 solution at room temperature and its subsequent heating at 80 °C. The process results in the formation of a macro porous gold nanocomposite consisting of gold nanoparticles embedded in the cuttlebone-derived organic matrix background, which shows the characteristic plasma absorption of gold nanostructures. UV-vis-IR spectrophotometer and transmission electron microscope (TEM) were used to characterize the gold nanocomposite and trace the formation process. A highlight of the research is that we adopted a nontoxic and renewable reagent of cuttlebone-derived organic matrix, which functioned as the reducing reagent, stabilizer and scaffold for the synthesis of gold nanoparticles.
