Abstract:In this paper, nitrogen and sulfur co-doped graphene(NSG) was used as a new carrier material for fixation of CuO nanoparticles, and the obtained CuO-NSG was applied as a catalyst for electrocatalytic glucose oxidation(EGO) to non-enzymatic glucose sensor to solve the scarcity and high cost of EGO catalyst. The results show that the NSG give CuO-NSG greater surface area, and strong interfacial coupling between NSG and CuO. Due to the significant effect of NSG and the synergistic effect of NSG and CuO, CuO-NSG showed higher EGO activity than CuO and CuO-RGO. The CuO-NSG based sensor demonstrated excellent glucose sensing performance with high sensitivity of 1 722 μA·mmol·L-1·cm-2 and low detection limit of 0.07 μmmol·L-1, as well as good detection performance in selectivity, reproducibility, stability and feasibility in actual sample analysis.
