Fig. 6From: A Facile One-Pot Synthesis of Au/Cu2O Nanocomposites for Nonenzymatic Detection of Hydrogen Peroxide a Amperometric current curve of the Au/Cu2O/GCE with the successive addition of H2O2 into the stirring 0.1 M PBS (pH = 7.0) at −0.3 V. Inset is the amplification of the marked rectangle region shown in the curve. b The linear relationship between the catalytic current and the concentration of H2O2 Back to article page
