“…Morphologies of the final products were greatly affected by the molar ratio of AgNO 3 and HCl (Figure 1a~f). Uniform nanocubes with an edge length (l) of 516 ± 67 nm (mean ± one standard deviation) were obtained when the AgNO3: HCl ratio was 1:6 ( Figure 1a).…”

“…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.…”

“…1,2 It also has photocatalytic activities that are useful for water splitting and decomposition of organic pollutants. [3][4][5][6] It has been demonstrated that decoration of AgCl with Ag nanoparticles can greatly improve the light absorption property and photostability of the AgCl nanoparticles. [7][8][9] In addition, AgCl can be used in fabricating antiseptic catheters, bone cements, and fabrics owing to its antibacterial property.…”

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 hybridization of AgX or Ag/AgX with other nonphotocatalytic materials (shown in Table 3) specially the carbon-based conductive matters has attracted extensive concerns due to their unique electronic properties and high specific surface area [306][307][308][309][310][311][312][313][314][315]. In hybridization aspect between AgX and photocatalytic substrates, the photocatalysis elevation is based on the Z-scheme heterogeneous structure formation in order to gain high charge separation efficiency [316][317][318][319][320][321].…”

The silver halides and their corresponding composites would constitute remarkable photocatalytic systems not only in energy production but also in environmental remediation. The major advantage in these silver halides system is that plasma metal Ag 0 species would be spontaneously generated by silver halides under light irradiation, which play dual roles of expanding light absorption range and charge carriers separation. In this tutorial review, the origin and development of silver halides, synthesis methods, construction of composite structures with other materials, photocatalytic applications, and various and controversial mechanisms are all exhaustively described.

Zeolite Y is a cage-like alumina silicate which is widely used as solid support to immobilize metal and metal sulfide nanoclusters. We have attempted to synthesis silver nanoparticle-loaded zeolite Y by an ion exchange method followed by a biogenic reduction method using lemon juice as a reducing agent. The antimicrobial activity of the silver ion, silver nanoparticles and silver chloride-modified zeolite was investigated against various Gram negative and Gram positive microorganisms. The silver nanoparticle-loaded zeolite was further functionalized with amoxicillin antibiotic which exhibited a strong antimicrobial action to kill drug resistant microorganisms. The catalytic behavior of silver nanoparticles was investigated to reduce 4-Nitrophenol in presence of NaBH 4 . The catalytic reaction is found to be pseudo-first order, resulting in a rate constant that was comparable with previously-reported results.
