The proposal of the research is used localized surface plasmon resonance (LSPR) of gold nanoparticles (Au NPs) modified Cuprous Oxide/Zinc oxide nano-rod array (Cu2O/ZnO NRA) composite electrode to apply in non-enzymatic glucose sensor. An anodic aluminum oxidation (AAO) method is used for growing aluminum array holes, then ZnO is grew in these holes by hydrothermal method to form ZnO NRA. Cu2O is electrodeposited on ZnO NRA at different pH values from 4 to 10. Au NPs are prepared by chemical synthesis and is uniformly dispersed on the surface of Cu2O/ZnO NRA by Nafion dispersant. The stability and linearity of the glucose sensing electrode of Cu2O/ZnO composite materials are improved by utilizing the catalytic, stable and high-sensitivity characteristics LSPR of Au NPs. Scanning electron microscope (SEM) is used to check the array hole size of the AAO. A sorption spectrum of ZnO is used to verify the energy gap. The sensor would be tested by the chronoamperometry method with the increasing of glucose concentration. The calibration curve of glucose sensor has linear ranges: 7.41-11.111 mM and the sensitivity of 315.67 μA/M-1 cm-2.
