Homogenous Catalysts

Homogenous catalysis is a growing area in the chemical industry. Where highly specific reactions are desired, homogenous catalysis provides an excellent choice. Also, if a reaction occurs in the presence of a homogenous catalyst, then by definition it occurs in one phase, normally in the liquid phase. The metal in a homogenous catalyst is more effectively utilized then is the case in heterogenous systems. This means that processes can be operated under mild conditions with significant savings in energy related operating costs. Homogenous catalysts operate with relatively long lifetime and the use of advanced technologies has reduced catalyst poisoning and improved catalyst longevity.

Silver compounds from Alfa Aesar are used in a multitude of applications, ranging from pharmaceutical and chemical to energy, medical and many more.


Many silver salts are the chemical precursors for other silver compounds or metallic silver.

Laboratory Reagent

Silver carbonate has been employed in the Koenigs-Knorr reaction, a substitution reaction of a glycosyl halide with an alcohol to give a glycoside. Alternatively, the reaction can be promoted with either various heavy metal salts or other silver salts, including silver triflate. Whilst the decarboxylation of silver carboxylates leads to corresponding carboxylic acid (Hunsdiecker reaction).


The medicinal properties of silver salts have been used in a range of pharmaceutical compositions. Among its biological uses in histology, silver nitrate will demonstrate the presence of proteins and nucleic acids.

Medical & Medical devices

Silver and silver salts have been used extensively throughout history for a variety of medical purposes. Recently silver salts have been incorporated into sterile dressings.

Fuel cells & Solar energy materials

Silver salts are in use in a variety of electrochemical applications, such as fuel cells, in which they exhibit ionic conductivity.

Electrodes for potentiometric measurement

For potentiometric measurement, electrochemists will use a silver/silver chloride electrode as a matter of choice.

Photographic film industry

Silver compounds have been historically used in photography. The silver products used are light-sensitive and undergo fast photoinduced chemical reduction to metallic silver particles.

Glass industry - Cement and coloring agents

Stained glass can be tinted yellow with silver nitrate. Silver chloride is widely employed as a transparent cement in glass-to-metal seals, for example as a sealant in cathode ray tubes.

Other uses

Applications of silver salts include use as a scrubber to remove CO2 gas and electrodes in watch batteries.
