The cyclic voltammogram shows two pairs of peaks with formal potentials at 0.23 V and 0.86 V which are characteristic peaks of Prussian‐blue/Prussian white (PB/PW) and Prussian blue/Berlin green (PB/BG) transition and one sharp peak with formal potential at 0.68 V which represents Fe 3+ /Fe 2+ redox transition in MnHCF . UV‐Vis spectrum shows very intense peak at 750 nm, characteristic of metal to metal charge transfer (MMCT) band in PB, confirm the presence of PB in the nanocomposite (Figure A).…”

Prussian blue-manganese hexacyanoferrate (PB-MnHCF) nanocomposite is electrochemically deposited on glassy carbon (GC) electrode by potential cycling method from solution containing equimolar mixture of Fe 3 + , Mn 2 + and [Fe(CN) 6 ] 3À ions. The film is characterized by CV, XPS, EDS, UV-Vis spectroscopy and the surface topography is seen by AFM technique. It shows high specific capacitance of 1333 AE 95 F g À1 (areal capacitance of 11 AE 0.5 mF cm À2 or absolute capacitance of 767 AE 34 mF), high specific power density of 3475 AE 97 W kg À1 , high specific energy density of 185 AE 13 W h kg À1 at a current density of 7 A g À1 and excellent cycling stability (93 % capacitance retention up to 500 cycles) at a scan rate of 50 mV s À1 in 0.1 M KNO 3 (pH = 2) medium. It shows selective and sensitive electrocatalytic response towards H 2 O 2 reduction with high sensitivity and low detection limit. It also shows electrocatalytic response towards ethanol oxidation with lower values of charge transfer resistance and Tafel slope along with prolonged stability in acidic solution. All of these demonstrate its potential candidature as a multifunctional high performance non-precious electrode material for electrochemical supercapacitors, hydrogen peroxide sensing and ethanol oxidation.[a] R.

Nano-CuO particles are prepared by using Cu(NO3)2 and NH4HCO3 as the starting materials and pure water as the solvent. And use high-energy ball milling method to make nano-CuO particles embeded in the crystalloid surface of graphite to form composite particles. The products of nano-CuO and composite particles are characterized by using techniques such as X-ray powder diffraction, FTIR-spectroscopy, scanning electron microscopy, and separator-size analyzer. The results show that the average size of CuO particles is 11.2nm, the Median diameter of composite particles is 8.43μm. After the graphite is rapidly ball milled and loaded nano-CuO particles. The lamellar and pore structure of graphite are well maintained, And nano-CuO particles are loaded on the top of the hole and the hole wall.

Manganese dioxide modified glassy carbon electrode (MnO 2 /GC) was prepared by a novel film plating/cyclic voltammetry method for the determination of H 2 O 2. A manganese film was first cathodically deposited on the surface of glassy carbon electrode from MnCl 2 solution at the potential of −1.4 V versus Ag/ AgCl (satd. KCl), and then a well defined manganese dioxide was deposited on the surface of glassy carbon electrode by cyclic voltammetry at potential range −0.6 ~ 0.6 V, scan rate 100 mV s −1 in 0.1 mol L −1 NaOH solution. The resulted modified electrode was characterized by cyclic voltammetry and scanning electron microscopy (SEM), which showed excellent electrocatalytic activity for the oxidation of H 2 O 2. The chronoamperometric detection of H 2 O 2 was carried out at 0.6 V in phosphate buffer solution pH 7.38 containing 0.1 mol L −1 KCl and the linear relationship of response current on H 2 O 2 concentration was obtained in the range from 4.1×10 −10 to 1×10 −4 mol L −1 with a minimum detectable concentration of 3×10 −10 mol L −1 [S/N (signal noise ratio) = 3]. The response time of the electrode to achieve 95% of the steady-state current was < 2 s. No measurable reduction in analytical performance of the modified electrode was found by storing the electrode in ambient conditions for 30 days. This modified electrode has many advantages such as simple preparation procedure, remarkable catalytic activity, good reproducibility and long term stability of signal response during hydrogen peroxide oxidation. The deposition of manganese dioxide on the surface of GC appears to be a highly efficient method for the development of a new class of sensitive, stable and reproducible hydrogen peroxide electrochemical sensor.
