By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanoparticles. According to news reporting originating in Chongqing, People's Republic of China, by NewsRx journalists, research stated, "The reduced state carbon dot (r-CD) is a new kind of carbon dot (CD) prepared by using sodium borohydride. Herein, we find that the r-CDs can directly reduce chloroauric acid to form gold nanoparticles (AuNPs) without adding other reducers or stabilizers."
The news reporters obtained a quote from the research from Southwest University, "At the same time, we deduced that the hydroxyl groups (-OH) on the surfaces of r-CDs can act as both reducer and stabilizer for the synthesis of AuNPs. The AuNPs possess intrinsic catalytic activity, but compared with the AuNPs synthesized by citrate reduction, the AuNPs we prepared exhibit less excellent catalytic activity in the reduction of 4-nitrophenol (4-NP) with sodium borohydride. Conversely, for catalyzing oxidation of the substrate 3,3',5,5'-tetramethylbenzidine (TMB) by H2O2, the AuNPs we prepared show much higher catalytic activity than the AuNPs synthesized by citrate reduction."
According to the news reporters, the research concluded: "This work may open up a new route for the applications of CDs."
