Full textIn this work, a simple, less time consuming electrochemical method in the form of an electrochemical sensor has been developed for the detection of PAHs. The sensor was fabricated by the deposition of silver-gold (1:3) alloy nanoparticles (Ag-AuNPs) on ultrathin overoxidized polypyrrole (PPyox) film which formed a PPyox/Ag-AuNPs composite on glassy carbon electrode (PPyox/Ag-AuNPs/GCE). The silver-gold alloy nanoparticles deposited to form the composite were chemically prepared by simultaneous reduction of silver nitrate (AgNO3) and chloroauric acid (HAuCl4) using sodium citrate and characterized by UV-visible spectroscopy technique which confirmed the homogeneous formation of the alloy nanoparticles.

This is an account of the synthesis of several drastically different forms of silver nanoparticles: Bare metal nanoparticles, dry nanoparticulate powders, aqueous soluble particles, and organic ligand coated monodisperse silver nanoparticles were all produced. The synthetic method was adapted from previous studies on gold nanoparticles and investigated to understand the optimal conditions for silver nanoparticle synthesis. Also the procedure for refinement of the nanoparticles was studied and applied to the formation of alloy nanoparticles. This extraordinary procedure produces beautifully colored colloids of spherical metal nanoparticles of the highest quality which under suitable conditions self-assemble into extensive three dimensional superlattice structures. The silver nanoparticle products were later tested against several biological pathogens to find dramatic increases in antimicrobial potency in comparison to commercially available silver preparations.

Sulfide anion in wastewater causes serious environmental problem because it has the potential to threat living systems. Because of the latent toxicity, it is important to detect sulfide anion quickly in aqueous media. For sulfide anion determination, the electrochemical techniques are able to provide precise, sensitive, and fast response to the target species. Two-dimensional (2D) graphene sheets have large surface area, great electrical conductivity and have the potential applications in electrochemical sensing of chemical species, also noble metal NPs are well-known highly reactive electrochemical materials. The goal in this research is to develop a electrochemical sensor based on silver-gold alloy grown on gold nanoparticles/graphene composites (AuAgGO) modified screen-printed electrodes. In this study, graphene oxide (GO) is produced by Hummers method, we have developed a simple method for the synthesis of AuAgGO by a two-step photo-deposition method, in addition AuAgGO with different alloy shell thickness can be prepared by changing the loading amount of silver. Cyclic voltammetry was used to measure the electrochemical activity of the materials for the presence of sulfide ions in aqueous solution. The result shows that AuAgGO responses to sulfides increases with increasing silver content. Next, the AuAgGO electrode was subjected to the measurement of the modulation sweep rate in the diluted sulfide solution. To show that this system is controlled by diffusion kinetics. The AuAgGO sensor performs a linear sensitivity concentration correlation for the detection of sulfide. In this study, it was found that the addition of silver-gold alloy nano gold particles to the upper surface of the graphene oxide film is an effective method to improve the response and sensitivity.

The heterogeneously catalytic CO Oxidation with Au-Ag alloy deposited on inert and acidic mesoporous aliminosilicate MCM-41 support, prepared by either one-pot or two-step procedure, has been investigated in terms of the experimental kinetics, in-situ DRIFTS, O2 pulse adsorption, O2-TPD and theoretical reaction modeling. For one-pot/3:1 Au-Ag/MCM-41 alloy catalyst, the unexpectedly high catalytic activity at 80oC may be associated with the non-dissociative and non-competitive adsorption Langmuir-Hinshelwood model between CO and O2 species in intimate proximity on the alloy surface. The small activation energy, negligible surface coverage and desorption with raising temperature for both CO and O2 may give rise to the unusual behavior in reaction rate above 80oC. At higher temperature, the different reaction behavior and/or active site for CO oxidation could be altered, which may behave like supported monometallic metal catalyst. For two-step/5:1 Au-Ag/MCM-41 catalyst, the high catalytic activity at 80oC could be due to non-dissociative and non-competitive or competitive Langmuir-Hinshelwood model between adsorbed CO on Au and O2 on Ag in close proximity of Au-Ag alloy surface as the RDS. The decrease in CO conversion with the increasing temperature could be caused by either desorption of both CO and O2 or dissociative adsorption for O2 on the Au-Ag alloy surface. Anthracene hydrogenation in aqueous micellar solutions at room temperature is homogeneously catalyzed by ionic-surfactant-protected Au and Ag nanoparticles with well-controlled particle sizes. A remarkable size-dependence of catalytic activity is derived. The difference in the optical property of meal nanoparticles could be related to the charging of their surfaces, indicating that both the metal nanoparticles play a role as the nanoelectrode storing electrons from hydrides. The behavior about the electron transfer-relaying effects of metal nanoparticles is proposed for the hydrogenation reaction.
