Silver Carbon Core Shell Nanoparticles (Ag/C, 99.9%, APS: 80-100nm, Metal Core/Metal Shell)

Silver Carbon Core-Shell Nanoparticles

Silver-carbon core-shell nanoparticles are a class of nanomaterials where silver (Ag) serves as the core material, and carbon (C) forms the shell. This composite structure combines the unique properties of silver, a noble metal, with the versatility and functionalization potential of carbon.

Applications:

Biomedical Applications

Antimicrobial and Antiviral Properties: Silver is well known for its antimicrobial activity, which is enhanced by its nanostructure. Silver nanoparticles can interact with bacterial and viral membranes, disrupting their structure and leading to cell death. When combined with a carbon shell, silver-carbon core-shell nanoparticles can offer prolonged stability, controlled release, and reduced cytotoxicity compared to pure silver nanoparticles, making them useful in medical applications such as wound healing, infection control, and drug delivery systems.

Catalysis and Energy Applications

Catalysis: The combination of silver’s catalytic properties (particularly in oxidation reactions) with the high surface area of the carbon shell can be exploited in various catalytic processes. Silver-carbon core-shell nanoparticles can be used in the catalysis of organic reactions such as hydrogenation, oxidation, and reduction reactions. The carbon shell also serves as a support material, stabilizing the silver core and providing additional catalytic sites for enhancing reaction rates.

Energy Storage: In energy storage devices, such as supercapacitors and batteries, silver-carbon core-shell nanoparticles can act as both conductive materials and energy storage elements. The silver core provides excellent conductivity, while the carbon shell offers high surface area for ion adsorption and energy storage. This makes them promising candidates for high-performance supercapacitors, which require both high conductivity and large capacitance.

Environmental Applications

Environmental Remediation:  are used in environmental cleanup due to their high surface area, reactivity, and stability. The silver core can degrade organic pollutants and heavy metals, while the carbon shell can adsorb and stabilize these contaminants. These nanoparticles are ideal for water purification and air filtration systems, where they can be used to remove pollutants, such as toxic metals (e.g., lead, mercury), organic dyes, and other hazardous substances.
