A Novel Non-Enzymatic Electrochemical Hydrogen Peroxide Sensor Based on a Metal-Organic Framework/Carbon Nanofiber Composite

Abstract: A co-based porous metal-organic framework (MOF) of zeolitic imidazolate framework-67 (ZIF-67) and carbon nanofibers (CNFs) was utilized to prepare a ZIF-67/CNFs composite via a one-pot synthesis method. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD) were employed to investigate the morphology, structure, and composition of the resulting composite. A novel high-performance non-enzymatic electrochemical sensor was constructed based on the ZIF-67/CNFs c… Show more

“…It has been found that some MOFs were applied as peroxidase mimetic with catalytic activities and nonenzymatic electrochemical hydrogen peroxide sensors. [22,45] Thus, in this work, it is proposed that H 2 O 2 was adsorbed in the pores of Ni-MOF and absorbed hydrogen peroxide was reduced into H 2 O along with the oxidation of 1,4-dihydropyrines to corresponding pyridines (Scheme 3).…”

“…It can be seen from Figure 10 that the ORR in 0.08 M H 2 O 2 /0.10 M KOH solution was shifted from the ORR in O 2 ‐saturated 0.10 M KOH solution because some of the H 2 O 2 decomposition according to Equation 5 and the E 0 cell value was calculated according to Equation 1 by the theoretical Gibbs free energy (▵G 0 ) from the appendix of Atkins′ Physical Chemistry, the calculated E 0 cell was 1.2471 V. This resulted to the ORR shift to higher positive potential. For hydrogen peroxide reduction reaction (HPRR), it occurred at the negative potential of around −0.15 to −1.00 V, following Equation [134–146] trueΔnormalG=nFE0cell4pt …”
