Synthesis of AgInS2 nanostructure by microwave–ultrasonic method and characterization and photocatalytic properties

Abstract

In this Letter, sodium dodecyl sulfate (SDS) was applied not only as surfactant, but also as sulfur source to produce AgInS 2 . Nanostructures were characterized extensively by means of X-ray diffraction, energy-dispersive X-ray analysis, scanning electron microscopy, transmission electron microscopy and infrared spectrum. Nanoparticles have been successfully synthesized through an microwave-ultrasonic method by employing mixture of InCl 3 , AgNO 3 as silver precursor and SDS in 40 ml of propylene glycol as a solvent. This method is novel, simple and can be easily controlled. Effects of different parameters such as power, and time of irradiation were investigated.

Transformation of Indium and Gallium Metal into Mixed Group 11/13 Ternary Sulfide Nanoparticles by Using a Dithioic Acid

“…Currently, a variety of synthetic methods are available for the synthesis of mixed Group 11/13 ternary chalcogenide nanoparticles including hydrothermal, solvothermal, hot injection, solution decomposition, and microwave irradiation . This latter method has attracted particular attention because of improvements in reaction times, purity, and reproducibility .…”

“…tion. [18][19][20] This latter method has attracted particular attention because of improvements in reactiont imes, purity,a nd reproducibility. [19] All of the methods employ ar ange of Group 11 metal sources, for example, AgNO 3 , [5,14] Ag(dedc) (dedc = diethyldithiocarbamate), [3,17] Ag 2 S, [9] CuCl, [15,21] and CuNO 3 ; [11] and Group 13 metal sources, fore xample, InCl 3 , [5,14] [In(dedc) 3 ] (dedc = diethyldithiocarbamate), [3,17] In(NO 3 ) 3 , [3,11] GaCl 3 , [21,22] and Ga 2 S 3.…”
