Abstract
A new, direct, simple and high yield solution phase synthesis for preparing narrow-sized silver nanoparticles by chemical reduction in aqueous solution of AgNO3 in the presence of incorporated Sn particles in methyltrimethoxysilane (MTMS) at room temperature is reported. The resulting MTMS-silver nanoparticles were characterized by means of powder X-ray diffraction and transmission electron microscopy. The produced Ag particles present a tight size distribution with an average diameter of about 15 nm. Dispersed silver nanoparticles in tetrahydrofuran-dimethylformamide (1:1) mixture exhibit some broad surface plasmon resonance bands in UV–visible spectrum.
Highlights
Because the recent decades, many studies have been carried out on the materials in the nanoregime on the nanoparticles (NPs) of noble metals
A novel simple and economic method is used for the production of silver nanoparticle through chemical reduction of aqueous solution of AgNO3 in the presence of incorporated metal tin in methyltrimethoxysilane (MTMS) at room temperature
The particle sizes of both samples were calculated by substituting full width at half maximum (FWHM) and position of intense peak in Scherrer’s equation: D 1⁄4 0:9k ð1Þ
Summary
Many studies have been carried out on the materials in the nanoregime on the nanoparticles (NPs) of noble metals. Metal NPs with properties between bulk materials and molecules display interesting linear and nonlinear optical, electronic and chemical properties which differ significantly from those of the corresponding bulk metal (Ozin 1992). A novel simple and economic method is used for the production of silver nanoparticle through chemical reduction of aqueous solution of AgNO3 in the presence of incorporated metal tin in methyltrimethoxysilane (MTMS) at room temperature. Silver nitrate (AgNO3), which was purchased from Aldrich, was used without any further purification in this study. Tetrahydrofuran (THF), dimethylformamide (DMF) and MTMS (C4H12O3Si; MTMS) were purchased from Merck. Double-distilled water was used during the procedure of the sample preparations
