Nickel hydroxide deposited indium tin oxide electrodes as electrocatalysts for direct oxidation of carbohydrates in alkaline medium

Bifunctional, Carbon-Free Nickel/Cobalt-Oxide Cathodes for Lithium-Air Batteries with an Aqueous Alkaline Electrolyte

“…The cathodic peak at around 1.25 V is associated with the reduction of nickel oxyhydroxide back to nickel hydroxide [34,35,40,41]. With increasing Co 3 O 4 content the current density rises constantly and reaches its maximum at a content of 20 wt.-% Co 3 O 4 and 70 wt.-% nickel.…”

Resolution of galactose, glucose, xylose and mannose in sugarcane bagasse employing a voltammetric electronic tongue formed by metals oxy-hydroxide/MWCNT modified electrodes

“…The development of non-enzymatic carbohydrates sensors has risen at a considerable rate, many efforts have been made to find new electrocatalytic materials for oxidation of glucose and carbohydrates such as: cobalt hydroxide nanoparticles electrodeposited on the surface of glassy carbon electrode [9], multiwall carbon nanotubes containing copper oxide nanoparticles [10], copper hydroxide nanotubes [11], nickel hydroxide nanoparticles on boron-doped diamond electrodes [12], carbon nanotubes/copper composite electrodes [13], copper(II) oxide nanorod bundles [14], gold nanoparticle-constituted nanotube array electrode [15], palladium nanoparticles supported on functional carbon nanotubes [16], palladium nanoparticles distributed on surfactant-functionalized multi-wall carbon nanotubes [17], Nickel/cobalt alloys modified electrodes [18], nickel hydroxide deposited indium tin oxide electrodes [19], Au-CuO nanoparticles decorated reduced graphene oxide [20] and glassy carbon electrode decorated with multi-wall carbon nanotubes with nickel oxy-hydroxide [21].…”

Detection of Several Carbohydrates Using Boron-doped Diamond Electrodes Modified with Nickel Hydroxide Nanoparticles

“…The great majority of past research has focused on glucose oxidation, and to our knowledge, few works have studied other carbohydrates, like sucrose, xylose, lactose, fructose, maltose, arabinose and rhamnose. 17,44,[46][47][48][49] Recently, our group studied the kinetics of electrooxidation of different carbohydrates at a glassy carbon electrode modified with carbon nanotubes decorated with nickel oxy-hydroxide. 17 A our interest is to study the electroanalytical response of several carbohydrates at BDD modified with nickel hydroxide for future determination of these carbohydrates in lignocellulosic material of sugar cane, which are important in the second-generation ethanol production.…”
