Abstract

Here we demonstrate the synthesis of benzimidazolones from -phenylenediamines and carbon dioxide in the presence of gold nanoparticles supported on a composite material based on microcrystalline chitosan from shrimp shells and fibrous phosphosilicate (CS-FPS/Au). The results showed that the gold nanoparticles were stable with the P, N and O atoms of CS-FPS. The morphology and structure of FPS leads to a higher catalytic activity. The CS-FPS/Au NPs were thoroughly characterized using TEM, FESEM, TGA, FTIR, and BET.
