Simultaneous determination of acetaminophen and tyrosine using a glassy carbon electrode modified with a tetraruthenated cobalt(II) porphyrin intercalated into a smectite clay

Simultaneous quantification of acetaminophen and tryptophan using a composite graphene foam/Zr-MOF film modified electrode

“…5A) for 51.2 µM of AC and 12 µM TRYP, respectively. These results are close to 0.5, indicating that the electrochemical oxidation of these two compounds at GF/UiO-66/GCE electrode was predominately governed by diffusion 10 and their surface was not fouled by these analytes.…”

“…5B, curve c) ): Interestingly, at UiO-66/GCE, α was found to be 0.4 (see Fig. S5 B) implying that the number of electrons involved in AC electrochemical redox is two as reported in literature 10 , half of the number of electrons involved when the composite modified GCE was used. This suggests that overall oxidation process of AC is complex.…”

“…For example, a zinc hexacyanoferrate clay modified electrode for electroanalysis of tryptophan was previously developed 9 . Subsequently, a sensitive glassy carbon electrode modified with a tetraruthenated cobalt (II) porphyrin intercalated into a smectite clay for simultaneous determination of acetaminophen and tyrosine was also developed 10 . Apart from clay materials, recently, carbon nanomaterials (e.g.…”

Electrocatalytic Oxidation and Sensitive Determination of Paracetamol Based on Nanosheets Self‐assembled Lindgrenite Microflowers

“…Thus, it is necessary to detect the concentration of paracetamol in human serum. Due to the development of material science, many new nanostructured materials with novel characteristics have been developed and applied in the determination of paracetamol . Many kinds of polyoxometalate (POM) nanomaterials have been developed due to their excellent properties of catalysis .…”

A sandwich-type catalytic composite reassembled with a birnessite layer and metalloporphyrin as a water oxidation catalyst

“…12,13 Metalloporphyrin compounds have a planar macrocyclic structure, excellent optical and electrical properties, and light and heat stability, making it an important application prospect in many elds, especially in the eld of biomimetic catalysis. [14][15][16][17][18] Considering that the intercalations of metals and other substances into birnessite will enhance OER performance, and the success of porphyrin intercalates into layered materials such as insulating hexagonal boron nitride (h-BN) monolayer and thiosalicylic acid-modied Mg-Al layered double hydroxides, [19][20][21][22][23][24][25][26] we hypothesized that intercalation of metalloporphyrin into layered birnessite can make use of the good stability of metalloporphyrin and the good electronic mobility in the porphyrin ring, thus strengthening the charge transfer performance of birnessite. In this paper, a new organic-inorganic composite, sandwich-type catalytic material MnTAPP@bir, was synthesized.…”
