Granular nanowires with a diameter of about 60 nm were fabricated from cuprous oxide (Cu2O) by an electrochemical method using anodic aluminium oxide as the template. A non-enzymatic sensor for hydrogen peroxide (H2O2) was then developed on the basis of a gold electrode modified with Cu2O nanowires and Nafion. The resulting sensor enables the determination of H2O2 with a sensitivity of 745 μA mM−1...
Tubular tetrapod magnesium oxide (tt-MgO) can be synthesized by thermal evaporation of Mg metal powder with a pre-grown tetrapod ZnO template. The morphology and structure of the tt-MgO were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. A composite prepared from tt-MgO, nafion and horseradish peroxidase was employed to modify a gold electrode...
