Resumen

Abstract—Gold nanoparticles have been synthesized using chloroauric acid and sodium dodecyl sulfate (SDS) as the surfactant in water. These nanoparticles are analyzed using UV–vis spectroscopic, Transmission electron microscopy and Dynamic light scattering technique. It is spherical in shape, having a size of 50-280 nm. The result shows that SDS coated gold nanocatalyst is highly active in the degradation of methylene blue (10 mg/L) in sunlight (~75%) for 4.0 h.
