All Procedures for the Synthesis of Silver Nanosheets

Abstract

Two dimensional silver(I) coordination polymer, [Ag(μ₅-T4S)]_n (<strong>1</strong>), (T4S^- = toluene-4-sulfonate), has been synthesized and characterized by Inductively Coupled Plasma (ICP) and elemental analyses, IR spectroscopy and powder X-ray diffraction. This compound was calcined at 450, 500 and 700 °C in a furnace and static atmosphere of air. The resulting compound from <strong>1</strong> at 450 °C is a spongy nanostructure which could not be characterized due to its partial calcination process. At 500 and 700 °C, the compound is a mixture of silver and silver sulfate compacted nanosheets and microstructures. By increasing the temperature from 500 to 700 °C, the tendency for the formation of agglomerated mixture of silver and silver sulfate was increased. In addition, a number of one-step techniques including electrochemical deposition method, electroless deposition method, direct deposition method, redox reaction, mirror reaction, coating technique, self-seeding or self-assembling process and wet chemical method have been reviewed for the synthesis of two-dimensional nano silver.
