“…[58][59][60][61][62][63][64][65][66] Taking into account the differences between the techniques employed and the increase of surface area provided for some modifiers, the analytical parameters of Ni(OH)2/BDD for glucose in the present work are comparable to those reported previously. Thus, the use of the Ni(OH)2/BDD electrode for carbohydrate determination presented in this work is advantageous because it achieves a similar response and its preparation procedure is simple and fast when compared to other electrodes.…”

“…This fact indicates the irreversible oxidation of glucose, and a conversion of the NiO(OH) in Ni(OH)2. 57 The anodic peak shift can be attributed to the diffusion limitation of glucose at the electrode surface. When voltammetric behaviors of glucose at Ni(OH)2/BDD and pretreated BDD are compared, a shift around 0.11 V for more cathodic potential is observed using the modified electrode, in addition to the pronounced increase of the peak current.…”

In this work the electrooxidations of glucose, galactose, mannose, rhamnose, xylose and arabinose are studied at a nickel hydroxide nanoparticle modified boron-doped diamond electrode and compared to an unmodified electrode. These carbohydrates are very important in the second-generation ethanol production process. Nickel hydroxide modified borondoped diamond was characterized by scanning electron microscopy and energy dispersive X-ray. Electrochemical impedance spectroscopy was employed to study the interface properties of surface-modified electrodes in the absence and presence of the carbohydrates. Limits of detection were 5.3 × 10 -5 , 6.8 × 10 -5 , 2.7 × 10 -4 , 6.9 × 10 -5 , 8.8 × 10 -5 and 2.6 × 10 -5 mol L -1 for glucose, galactose, mannose, rhamnose, arabinose, xylose, respectively.

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Ni-doped nanoporous carbons provided similar propargyl alcohol conversions for very low metallic contents. Nanoparticulated Ni on various carbon supports gave rise to the highest electrocatalytic activity in terms of product selectivity, with a clear dependence on Ni content. The results point to the importance of controlling the dispersion of the Ni phase within the carbon matrix for a full exploitation of the electroactive area of the metal. Additionally, a change in the mechanism of the propargyl alcohol electrooxidation was noted, which seems to be related to the physicochemical properties of the carbon support as well. Thus, the stereoselectivity of the electrooxidative reaction can be controlled by the active nickel content immobilized on the anode, with a preferential oxidation to (Z)-3-(2-propynoxy)-2-propenoic acid with high Ni-loading, and to propiolic acid with low loading of active Ni sites. Moreover, the formation of (E)-3-(2-propynoxy)-2-propenoic acid was discriminatory irrespective of the experimental conditions and Ni loadings on the carbon matrixes.

3D-networked carbon nanotube/diamond core-shell nanowires for enhanced electrochemical performance

et al. 2014

A boron-doped diamond/carbon nanotube (BDD-CNT) hybrid material with a core-shell three-dimensional random network structure was fabricated using the electrostatic self-assembly of nanodiamond. In general, CNTs are easily etched out as hydrocarbons or transformed to graphitic clusters at defect sites in hydrogen-rich environments (that is, the typical conditions employed for diamond deposition). However, attaching a dense layer of nanodiamond particles to the outer wall of the CNTs suppressed CNT etching and promoted BDD growth. To attach the dispersed nanodiamond particles on the CNT surface, we used an electrostatic self-assembly technique in which the surface charges on the CNTs and the nanodiamond were controlled using cationic and anionic polymers. Following BDD deposition, the electrochemical properties of the BDD-CNT structures were examined by cyclic voltammetry and electrochemical impedance spectroscopy. The results indicated that the BDD-CNTs exhibited enhanced electron transport efficiency, large effective surface areas and high sensitivity, with a remarkably low detection limit.
