Abstract
Due to the serious pollution issue caused by 4-nitrophenol (4-NP), it is of great importance to design effective catalysts for its reduction. Here, a novel and simple strategy was developed for the synthesis of carbon dot-decorated gold nanoparticles (AuNPs/CDs)
the
carbonization of organic ligands on AuNPs at room temperature. The enhanced adsorption of 4-NP on CDs
π-π stacking interactions provided a high concentration of 4-NP near AuNPs, leading to a more effective reduction of 4-NP.
