- Abstract
Cuprous oxide (Cu2O)nanomaterial has been successfully obtained by a simple sol-gel technique. The characterization indicated that the powders have a good crystalline structure, and the synthesis was successfully controlled in nanoscale.Cyclic voltammetry (CV) revealed that Cu2O cubebox exhibited a direct electrocatalytic activity for the reduction of hydrogen peroxide (H2O2) in sodium hydroxide solution. The enzyme-less amperometric sensor used in the detection of H2O2with detection limit of 81.69 M (S/N = 3) over wide linear detection ranges up to 0.39 mM and with a high sensitivity of 444.7 A•mM 1•cm 2, and a possible mechanism was also given in the paper.
