The use of copper(II) oxide nanorod bundles for the non-enzymatic voltammetric sensing of carbohydrates and hydrogen peroxide

Fine tuning of the morphology of copper oxide nanostructures and their application in ambient degradation of methylene blue

“…Polyethylene glycol (PEG), an inexpensive nonionic surfactant, has been used to assist the formation of metal oxides in previous researches [39][40][41][42][43]. PEG with uniform and ordered chain structure is easily adsorbed at the surface of metal oxide colloid.…”

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].…”

Tantalum oxide honeycomb architectures for the development of a non-enzymatic glucose sensor with wide detection range

“…This is attributed to the formation of thermodynamically less stable redox mediator Cu (III) and Ni (III) Lu et al, 2009). Various kinds of CuO nanostructures such as nanowires (Zhang et al, 2008), nonorods (Batchelor-McAuley et al, 2008) and nanoflowers (Umar et al, 2009) have been utilized for sensitive and selective amperometric detection of glucose (Wang et al, 2010b). Nanoporous and nanotubular structures of oxides of metals such as Zr (Tsuchiya et al, 2005), Ti (Paulose et al, 2006), W (Hahn et al, 2007), Nb (Wei et al, 2012), Al (Lee et al, 2008) and Ta (El-Sayed and Birss, 2009) possess enhanced surface area and high aspect ratio resulting in enhanced electrocatalysis.…”
