Montmorillonite-stabilized gold nanoparticles for nitrophenol reduction

open access: yesComptes Rendus. Chimie, 2019
Two gold-based catalysts were obtained by Au chemical reduction of the HAuCl 4 precursor. The resulting nanoparticles were stabilized and immobilized on montmorillonite (Mt) and montmorillonite-ceria (Mt/CeO 2 ).
