“…13 Despite the wide range of application of AgCl-related materials, there have been only a few methods available for the synthesis of AgCl nanoparticles such as microemulsion technique or matrix based technique. 3,14,15 Moreover, AgCl nanoparticles with controlled size and shape were produced only under particular conditions. For example, AgCl nanocubes which are surrounded by six (100) facets can be prepared using gelatin matrix.…”

“…For example, AgCl nanocubes which are surrounded by six (100) facets can be prepared using gelatin matrix. 15 Only very recently, much facile synthesis of AgCl nanocubes without using gelatin matrix has been demonstrated via a simple reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) in ethylene glycol. 9 Fine control of the size and shape of the AgCl-related materials may further enhance their catalytic, optical, and electronic properties as demonstrated with various metallic, semiconducting, and metal oxide materials.…”

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.

“…The introduction of NaBr leads to the surface conversion of AgCl to AgBr driven by the decrease in enthalpy of precipitation of the silver halides. 27 Because Ag + cations diffused outward more quickly than Br − diffused inward, nanoscaled Kirkendall voids were generated near the AgCl/AgBr interface. 19,28 Upon solar light irradiation, AgBr is excited to generate electrons at the conduction band and then react with Ag + to form Ag NPs across the surface.…”
