General description
Goldis a highly valued metal in catalysis and material science due to its uniqueproperties such as high chemical stability, excellent electrical and thermalconductivity, malleability, and ductility. In catalysis, gold nanoparticles areparticularly effective as catalysts for various chemical reactions, includingoxidation and hydrogenation processes due to their high surface area andexcellent catalytic activity. In material science, gold is often employed inthe fabrication of electronic components, sensors, and biomedical devices dueto its excellent conductivity, corrosion resistance, and biocompatibility.
Application
