“…A vast majority of the publications in the literature discussing plasmon‐enhanced photocatalysis have focused on reactions involving photocatalytic decomposition of organic compounds 23–54. These are typically dye molecules (e.g., methyl orange) whose decomposition rates can be easily observed by optical means 44.…”

In the past decade, the surface plasmon resonance of Ag and Au nanoparticles has been investigated to improve the efficiency of photocatalytic processes. The photocatalytic production of fuels is particularly interesting for its ability to store the sun's energy in chemical bonds that can be released later without producing harmful byproducts. This Feature Article reviews recent work demonstrating plasmon‐enhanced photocatalytic water splitting, reduction of CO2 with H2O to form hydrocarbon fuels, and degradation of organic molecules. Focus is placed on several possible mechanisms that have been previously discussed in the literature. A particular emphasis is given to several aspects of these mechanisms that are not fully understood and will require further investigation.

“…During the last decade, silver nanoparticles (Ag NPs) attract significant attention due to their unique optical, thermal, and electrical properties as well as their use as antibiotic materials, photocatalysts, and conductive nano-inks [1-7]. The methods to obtain Ag NPs of well-defined morphology, size, orientation, and complex pattern are the subject of numerous researches.…”

Silver nanoparticles were synthesized in linear and branched polyelectrolyte matrices using different reductants and distinct synthesis conditions. The effect of the host hydrolyzed linear polyacrylamide and star-like copolymers dextran-graft-polyacrylamide of various compactness, the nature of the reductant, and temperature were studied on in situ synthesis of silver sols. The related nanosystems were analyzed by high-resolution transmission electron microscopy and UV-vis absorption spectrophotometry. It was established that the internal structure of the polymer matrix as well as the nature of the reductant determines the process of the silver nanoparticle formation. Specifically, the branched polymer matrices were much more efficient than the linear ones for stable nanosystem preparation.

“…1S at Supplementary data). Both silver vanadates show UV and visible light absorption at 400-520 nm, but the absorption edge overlaps with a shoulder at 550 nm that suggests the presence of Ag 0 whose surface plasmon absorption increases the absorption in the visible range [15,17]. The presence of Ag 0 was no detected by XRD characterization so it will be discussed later by other techniques.…”

h i g h l i g h t s" Silver vanadates were synthesized by microemulsion methodology not exceeding 110°C. " Silver metallic nanoparticles decorated the surface of the silver vanadates. " The photocatalytic properties were studied upon visible light. " The stability of catalysts was evaluated after reaction. " We report a synergistic effect between Ag 0 particles and silver vanadates. a r t i c l e i n f oArticle history: Available online 5 December 2012 Keywords:Silver vanadates Visible-light-driven photocatalysts Used-catalysts characterization Dye photodegradation a b s t r a c tSilver vanadates with light absorption properties in the visible region were successfully prepared by a low temperature pathway (not exceeding 110°C) using an optimized microemulsion methodology. The resulting materials were evaluated as photocatalysts in Rhodamine B photodegradation and characterized before and after reaction. The silver vanadates displayed silver metallic nanoparticles decorating the surface. The as-prepared Ag 3 VO 4 catalyst was the most active. Nevertheless, this silver vanadate suffered important changes during reaction. The initial structure evolves yielding a silver pyrovanadate, Ag 4-V 2 O 7 , with a concomitant increase of the number and size of the silver metallic nanoparticles. The synergy between these Ag 0 particles and the photoactivity of the Ag 4 V 2 O 7 phase seems responsible of the high photoactivity of this material.
