Silver chloride sols preparation

Crystallization and reduction of sol-gel prepared zinc oxide films derived from zinc acetate by irradiation with an UV lamp (185 and 254 nm) was studied (Asakuma et al. 2003). UV irradiation induced the formation of hexagonal ZnO crystals from amorphous ZnO films preheated at 100 C, while irradiation of porous ZnO films preheated at 60 C led also to formation of metallic zinc. Composite ZnO/Cu and ZnO/Ag/Cu nanostructures were prepared via the photocatalytic reduction (wavelength 310-390 nm) of cuprous chloride and silver nitrate over the chemically prepared ZnO nanoparticles in aqueous solution (Shvalagin et al. 2004). Amorphous ZnO thin films were prepared... 

Alternate Names t-butylcyanodimethylsilane TBDMSCN. Physical Data bp 163-167 °C/760 mmHg mp 76-78 °C. Solubility sol organic solvents (methylene chloride, THF, chloroform) reacts rapidly with water and protic solvents. Preparative Methods conveniently prepared by refluxing t-butyldimethylchlorosilane (1 equiv), potassium cyanide (1.3 equiv) and 18-crown-6 (0.31 equiv) in dry methylene chloride under nitrogen. The reagent can also be prepared by the reaction of silver(I) cyanide with t-butyldimethylchloro-silane, or stirring at 60 °C for 4 h a mixture of sodium cyanide, Amberlite XAD-4 resin, and t-butyldimethylchlorosilane in acetonitrile. ... 

Sols of noble metals are usually prepared by reduction of a solution of a metal salt So gold sols are formed by the reduction of a solution of gold (III) chloride by formaldehyde, by hydrazine, by phosphorus and by other reducing agents, silver sols by reduction of silver oxide suspensions with hydrogen, etc ...
