The Premetek® silver catalyst section currently focuses on the Ag/C Vulcan XC-72 carbon-supported silver catalyst series, available in 20%, 40%, 60%, and 80% Ag loading grades. The page is organized using the actual models and specifications from the source file, allowing convenient comparison of Ag loading, particle size, metal surface area, and catalyst BET surface area. It is suitable for research in fuel cells, electrolyzers, sensors, and related electrochemical applications.
Premetek® silver-based catalysts are designed for electrochemical research and development, including fuel cells, electrolyzers, sensors, and related silver catalyst studies. This section centers on the Ag/C Vulcan XC-72 series, making it easy to compare different Ag loading levels while keeping the carbon support system consistent.
The Ag/C line covers four commonly used Ag loadings—20%, 40%, 60%, and 80%—and is well suited for studying how loading level influences particle size, metal surface area, and BET characteristics. For users who need rapid feasibility checks, research group purchasing, or parallel comparison across several models, this page can be used directly as a front-end selection tool.
This page preserves key technical data such as model number, support / morphology, assay, metal crystallite size, metal surface area, and catalyst BET, and also includes quick selection, FAQ, and purchase support modules for both website presentation and pre-purchase review.
Built on Vulcan XC-72 support, ideal for parallel screening of different Ag loading levels under a consistent support system.
Covering 20%–80% Ag, suitable for comparing both lower-loading and higher-loading catalyst routes.
Standard 1 g / 5 g packaging is well suited for laboratory screening, validation experiments, and budget planning.
Combines parameter comparison, pricing information, FAQ content, and purchasing support in one place.
