Facile chemical routes to mesoporous silver substrates for SERS analysis
Mesoporous silver nanoparticles were easily synthesized through the bulk reduction of crystalline silver(I) oxide and used for the preparation of highly porous surface-enhanced Raman scattering (SERS)-active substrates. An analogous procedure was successfully performed for the production of mesoporous silver films by chemical reduction of oxidized silver films. The sponge-like silver blocks wit...
متن کاملSERS: Materials, applications, and the future
The first observations of the Raman spectra of pyridine on roughened silver were made in 19741; however, at this time the authors did not recognize that these spectra were due to any unusual, enhanced, or new phenomena. Since its discovery in 19772, interest in and the use of surface enhanced Raman spectroscopy (SERS) has grown exponentially (Fig. 1). The SERS field has dramatically progressed ...
متن کاملFacile preparation of SERS-active nanogap-rich Au nanoleaves.
To simply reduce HAuCl(4) using 2-thiophenemethanol in an aqueous solution at room temperature, a novel metallic Au nanostructure with a high SERS activity was obtained. Flat sheet-like Au nanoleaves possessing many nanogap hotspots bound with a large percentage of high-index facets were obtained.
متن کاملMolecular Routes to Materials in New York
A symposium entitled “Molecular Routes to Materials” was held in New York City at the 4th Chemical Congress of the North American Continent in August, 1991. The talks focused on synthetic and mechanistic studies of the formation of metals, borides, nitrides, carbides, oxides, and compound semiconductors from molecular precursors. Dr. Joel Miller (DuPont) outlined recent success in obtaining mag...
متن کاملPreparation of silicotungstenic acid-containing mesoporous materials.
Silicotungstenic acid (STA)-containing mesoporous materials were directly synthesized in a nonaqueous medium by sol-gel method. X-ray powder diffraction showed that both as-synthesized and calcined materials possess mesoporous structure. STA contents in extraction solutions were analyzed with inductively coupled plasma. When STA/silica ratio changed from 1:100 to 1:4, the immobilization of STA ...
