Direct electrocatalytic reduction of hydrogen peroxide based on Nafion and copper oxide nanoparticles modified Pt electrode

Spontaneous formation of CuO nanosheets on Cu foil for H2O2 detection

“…Although satisfactory selectivity and great sensitivity are obtainable with enzymatic H 2 O 2 sensors, their inevitable drawbacks such as the chemical and thermal instabilities originating from the intrinsic nature of enzymes has turned recent efforts for direct determination of H 2 O 2 to enzyme-free electrodes. As a result, considerable research has been focused on catalysts based on transition-metal oxides as alternatives to noble metals such as Au and Pt, for highly efficiency non-enzymatic electrocatalytic applications [7][8][9].…”

Cobalt oxide nanostructure-modified glassy carbon electrode as a highly sensitive flow injection amperometric sensor for the picomolar detection of insulin

“…In addition, due to the low production cost, high stability, good electrical properties, low resistivity, and remarkable redox properties of metal oxide particles and nanoparticles, they are suitable for application in gas sensors [7][8][9]. Metal oxide or electron transfer mediators immobilized onto metal oxide films are suitable materials for sensors fabrication and electrode modification technologies [10][11][12][13][14][15][16]. Over the recent years, an increasing number of studies have focused on the production of novel; typically nanometer-scale forms of metal oxide include: ZnO [17], NiOx [18,19], CuO [20], MnOx [21], IrOx [22], cobalt oxide [23,24], and many others.…”

Synthesis of folding flake-like CuO sub-microstructure and its application on mercury (II) sensor

“…Nanomaterials with special physical and chemical properties have been widely applied in chemsensors and biosensors. Nanoparticles, nanotubes, nanowires such as Au [20], CuS [21], Fe 2 O 3 [22], MWNTs [23] and Si [24] have been extensively used in the field of electro-chemical biosensors due to their small size, large surface area, high surface reaction activity, high catalytic efficiency and corresponding potential electronic and chemical properties [25]. Among these nanomaterials, copper oxide has recently gained increased interest due to promising applications as heterogeneous catalysts for the oxidation of hydrocarbons [26], carbon monoxide [27], and biosensors [28][29][30], which has been used as sensors for the detection of glucose [28], [29,30] and Hg 2?…”
