The facile synthesis of aerogel-like alumina highly-loaded with gold nanoparticles

A facile approach is proposed for the stabilization of gold nanoparticles within alumina matrix based on fast coprecipitation of colloidal gold and alumina sol in the supercritical carbon dioxide used as antisolvent. Acetylacetone was used as a stabilizer agent for the synthesis of alumina sol. Gold...
