“…For comparison, several MnO 2 /GCEs were fabricated using an electrodeposition method [24]. It was found that MnO 2 /GCE shows no reproducible CV response because the MnO 2 layer is easily detached from GCE surface as reported for MnO 2 nanorod-modified GCE [27]. However, MnO 2 was Few reports have addressed the possible electrocatalytic mechanism of H 2 O 2 reduction at modified electrodes based on MnO 2 material.…”

“…Therein, MnO 2 is reported to be chemically reduced to Mn(OH) 2 species by H 2 O 2 , and then Mn(OH) 2 is oxidized to MnO 2 . Wang et al [27] proposed another mechanism based on redox reactions between high valence MnO 2 and low valence Mn species such as MnOOH, Mn(OH) 2 , or Mn 2 O 3 in neutral PBS using a ternary nanocomposite of Au nanoparticles-MnO 2 -reduced GO on GCE. However, the mechanism proposed in the literature [27] is a series of electron transfer reactions among the Mn species in which H 2 O 2 does not take part in the redox reaction.…”

However, the mechanism proposed in the literature [27] is a series of electron transfer reactions among the Mn species in which H 2 O 2 does not take part in the redox reaction. The reason that these mechanisms were suggested may be ascribed to the existence of voltammetric redox peaks observed in the absence of H 2 O 2 .…”

“…In recent years, manganese dioxide has been widely used as an electrode material for H 2 O 2 determination [17][18][19][20][21][22][23][24][25][26][27] owing to its excellent catalytic activity toward the decomposition of hydrogen peroxide [28], and the fact that it is an environment-friendly material [29]. Moreover, MnO 2 can be synthesized simply by one-step reduction of KMnO 4 and holds good stability on GCEs [25].…”

“…In addition, at a positive working potential, oxidizable substances such as ascorbic acid and uric acid can interfere with the precision of H 2 O 2 determination. To overcome these shortcomings of MnO 2 , various conducting materials such as noble-metal nanoparticles and carbon nanomaterials have been applied in the fabrication of MnO 2 -based electrochemical H 2 O 2 sensors [17,18,20,21,[24][25][26][27]. Among these conducting nanomaterials, polyaniline (PANI), which is one of the most commonly studied conducting polymers, is a promising material for chemical sensors owing to its easy and facile synthesis, high electric conductivity, environmental stability, and conductance controllability through simple acid/base doping/dedoping chemistry [33].…”

We report the synthesis of polyaniline-manganese dioxide (PANI-MnO 2 ) nanofibers and their applications as nonenzymatic electrochemical sensors for the determination of hydrogen peroxide (H 2 O 2 ). The PANIMnO 2 nanofibers were synthesized via a one-step mixing process from the as-prepared PANI nanofiber aqueous dispersion and the aqueous solution of KMnO 4 . The morphology and chemical composition of the synthesized PANI-MnO 2 nanofibers were characterized by field-emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy, and X-ray diffraction. A facile electrochemical hydrogen peroxide sensor based on a PANI-MnO 2 -modified glassy carbon electrode (PANI-MnO 2 /GCE) was fabricated by a drop-casting method, and its electrochemical behavior was investigated using electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and amperometry. The results clearly exhibited good electrocatalytic activity of the PANI-MnO 2 /GCE toward H 2 O 2 reduction in pH 7.4 phosphate buffer solution (PBS). The nonenzymatic H 2 O 2 sensor displayed a wide linear range (5-50 lM and 0.05-10 mM), low detection limit (0.8 lM at S/N = 3), high sensitivity (403.3 lA mM -1 cm -2 ), and negligible interference from ascorbic acid, uric acid, L-cysteine, and glucose at an applied detection potential of -0.4 V (vs. Ag/AgCl).

Cu(II)‐based MOF (Cu‐bipy‐BTC, bipy=2,2′‐bipyridine, BTC=1,3,5‐tricarboxylate) was synthesized and immobilized on multiwalled carbon nanotubes. The prepared composite was characterized by scanning electron microscopy (SEM), X‐ray diffraction (XRD), X‐ray photoelectron spectra (XPS) and IR spectra. Then the material was modified onto the surface of a glassy carbon electrode, and showed a couple of well‐defined redox peaks in a phosphate buffer solution (pH 6.0), ascribed to the redox process of CuII/I in the Cu‐bipy‐BTC. The modified electrode was then applied to fabricate a non‐enzymatic hydrogen peroxide biosensor. The sensor showed good electrocatalytic activity toward the reduction of hydrogen peroxide with a wide linear range (3–70 µmol L−1 and 70–30000 µmol L−1) and a detection limit of 0.46 µmol L−1, as well as good stability and repeatability. In addition, the sensor has been successfully applied to determine hydrogen peroxide in water samples with good accuracy. Thus, the Cu‐bipy‐BTC/MWCNTs composite has great potential for applications in electrochemical sensors.

A poly(2‐aminophenylbenzimidazole)/gold nanoparticles (P2AB/AuNPs) coated disposable pencil graphite electrode (PGE) was fabricated as an enzyme‐free sensor for the H2O2 determination. P2AB/AuNPs and P2AB were successfully synthesized electrochemically on PGE in acetonitrile for the first time. The coatings were characterized by scanning electron microscopy, X‐ray diffraction spectroscopy, Energy‐dispersive X‐ray spectroscopy, Surface‐enhanced Raman spectroscopy, and UV‐Vis spectroscopy. AuNPs interacted with P2AB as carrier enhances the electrocatalytic activity towards reduction of H2O2. The analytical performance was evaluated in a 100 mM phosphate buffer solution at pH 6.5 by amperometry. The steady state current vs. H2O2 concentration is linear in the range of 0.06 to 100 mM (R2=0.992) with a limit of detection 3.67×10−5 M at −0.8 V vs. SCE and no interference is caused by ascorbic acid, dopamine, uric acid, and glucose. The examination for the sensitive determination of H2O2 was conducted in commercially available hair oxidant solution. The results demonstrate that P2AB/AuNPs/PGE has potential applications as a sensing material for quantitative determination of H2O2.
