The construction of nanozymes at the at. level that hold structural stability and high enzyme-like activity is now a key factor in the optimization of an artificial enzyme. Single-atom metal/cerium oxide (CeO2)-based nanozymes have been demonstrated to possess a variety of enzymic activities and radical scavenging abilities, which are mainly attributed to the single-atom active site, redox valence states, and abundant defect chem. Here, we developed a single-atom Pd/CeO2 nanostructure by aqueous phase synthesis that exhibits the advantages of high yield and good stability. The Pd/CeO2 nanostructure possesses peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT) activities as well as reactive nitrogen species free-radical scavenging activity, exhibiting multienzyme-like activities and stability compared with CeO2 and other metal-based nanozymes. It is worth mentioning that the Pd/CeO2 nanostructure exhibits high POD-mimicking activity with a reaction rate of 0.88μM/min, about 5 times higher than that of the CeO2 nanozyme. In addition, the CAT-like activity of the Pd/CeO2 nanostructure is excellent, and its scavenging rate of hydrogen peroxide reached nearly 100% at a concentration of 50 ng/μL. The present work shows that single-atom Pd substitution is a promising strategy for the design of CeO2 nanozymes to exert better effects on biomedical applications, especially with diseases related to oxidative stress. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Related Products of 13820-53-6).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Related Products of 13820-53-6
