Facile Synthesis of Silver Chloride Nanocubes and Their Derivatives

Abstract

We demonstrate a facile route to synthesize silver chloride nanocubes and derivative nanomaterials. For the synthesis of silver chloride nanocubes, silver nitrate and hydrochloric acid were used as precursors in ethylene glycol, and poly (vinyl pyrrolidone) as a surfactant. Molar ratio of the two precursors greatly influenced the morphology and composition of the final products. As-synthesized silver chloride nanocubes showed size-dependent optical properties in the visible region of light, which is likely due to a small amount of silver clusters formed on the surface of silver chloride nanocubes. Moreover, we show for the first time that simple reduction of silver chloride nanocubes with different reducing reagents leads to the formation of delicate nanostructures such as cube-shaped silver-nanoparticle aggregates, and silver chloride nanocubes with truncated corners and with silver-nanograin decorated corners. Additionally, we quantitatively investigated for the first time the evolution of silver chloride nanocubes to silver chloride nanocubes decorated with silver nanoparticles upon exposure to e-beam. Our novel and facile synthesis of silver chloride related nanoparticles with delicately controlled morphologies could be an important basis for fabricating efficient photocatalysts and antibacterial materials.

Aqueous corn husk extract – mediated green synthesis of AgCl and Ag nanoparticles

“…The surface plasmon resonance (SPR) bands show a maximum of absorption at 450 nm corresponding to Ag when the volume is 1 to 5 ml. The synthesis performed with 8 ml of extract shows a wider band at 460 nm because there are larger NPs, as well as an absorption band located at 380 nm, which is characteristic of AgCl [4]. The inset in Fig.…”

Silver speciation and release in commercial antimicrobial textiles as influenced by washing

“…The Ag-NPs were synthesised by reduction of 1 mM silver nitrate (AgNO 3 ) with 2 mM sodium borohydride (NaBH 4 ) in the presence of 200 mg L À1 polyvinylpyrrolidone (PVP). PVP coated AgCl-NPs were prepared according to the method by Kim et al (2010) in ethylene glycol and were resuspended in water after centrifugation. The NPs were characterised by dynamic light scattering (DLS; NICOMP 380 ZLS, Particle Sizing Systems, FL, USA) and scanning electron microscopy (SEM; Quanta 450 FEG ESEM, FEI Company, OR, USA).…”

Sorption and desorption studies of radioiodine onto silver chloride via batch equilibration with its aqueous media

“…1 (the peaks at 27. 8, 32.2, 46.3, 54.8, 57.5, 67.4, 74.4, 76.7 and 85.3 C corresponding to hkl values of 111, 200, 220, 311, 222, 400, 331, 420 and 422, respectively) were related to the face-centered cubic (FCC) phase of AgCl (according to JCPDS card no.31e1238) indicating the high purity of the prepared AgCl (Tiwari and Rao, 2008;Kim et al, 2010).…”
