Synthesis sulfide nanomaterials

Silver sulfide materials on the nanoscale have also been studied considerably although they have not been explored as extensively as other transition group sulfides. One such work reports the development of silver sulfide nanomaterials using a one pot synthesis method wherein Ag(OAc) and dodecanethiol were mixed in a flask at RT and degassed for 15 minutes in N2 atmosphere.The solution was then heated to 205 °C for 100 minutes. Later the samples were washed and precipitated in... 

Rare-earth nanomaterials find numerous applications as phosphors, catalysts, permanent magnets, fuel cell electrodes and electrolytes, hard alloys, and superconductors. Yan and coauthors focus on inorganic non-metallic rare-earth nanomaterials prepared using chemical synthesis routes, more specifically, prepared via various solution-based routes. Recent discoveries in s)mthesis and characterization of properties of rare-earth nanomaterials are systematically reviewed. The authors begin with ceria and other rare-earth oxides, and then move to oxysalts, halides, sulfides, and oxysulfides. In addition to comprehensive description of s)mthesis routes that lead to a variety of nanoforms of these interesting materials, the authors pay special attention to summarizing most important properties and their relationships to peculiar structural features of nanomaterials s)mthesized over the last 10-15 years. 

Although nonaqueous sol-gel synthesis routes were mainly designed for metal oxide nanomaterials, the underlying chemical principles can be extended to many materials beyond metal oxides. In the following, we will separately discuss composites, organic-inorganic hybrids, metal sulfides, and metals, which all also have important technological applications [114],... 

The use of ultrasonic irradiation for producing nanomaterials has been a research topic of great interest (Dhasn et al., 1999). This is due to the simplicity of sonochemical method, the cheap price of the equipment and that in many cases the as-prepared material is obtained in the crystalline phase. The ultrasonic-assisted aqueous room tempjerature ionic liquid method was applied to prepare zinc sulfide and zinc oxide nanomateiials (Zheng et al. 2010 Jia et al. 2010), among many other nanomatreials. Selection of the room temp>erature ionic liquid was mainly based on the fact that it can be obtained at a relatively low price and the method for its synthesis is simple.
