Enhancement of the peroxidase-like activity of hollow spherical Fe_xNi_1−xS₂/SC nanozymes

Abstract

Artificial nanozymes receive considerable interest for their outstanding performance and wide application. However, their low activity resulted in a high concentration of substrates, costs, and environmental pollution. To enhance nanozymic...

Singlet Oxygen Formation Mechanism for the H2O2-Based Fenton-like Reaction Catalyzed by the Carbon Nitride Homojunction

“…The R ct value of HCCN (115.3 Ω) is significantly smaller than that of HCN (161.0 Ω) and CN (6140 Ω, Figure S3a). The lowest charge-transfer resistance and highest charge-transfer rate of HCCN induce the high catalytic activity. , The R ct value further decreased to 109.8 Ω after the addition of H 2 O 2 for HCCN (Figure b), indicating an extremely higher electron-transfer rate between HCCN and H 2 O 2 , which was more favorable for the Fenton reaction . In addition, the redox capacities of CN, HCN, and HCCN were investigated by CV (Figures c and S3b).…”

Compared to CN and HCN, the redox peak shifts toward a positive potential, and the current is enhanced for HCCN.…”
