▎ 摘　　要

Molybdenum disulfide/porous graphene (MoS/pGN) composite was synthesized by a simple hydrothermal method. The pGN was not easy to aggregate and could provide large surface for MoS2 growing. Therefore, the stacking of MoS2 nanosheets was effectively restrained and showed few. layer nanosheet structure, showing outstanding electrochemical feature. In addition, the pGN could shorten the diffusion pathways and facilitate the electron transfer of target analyte. Hence, the composite modified electrode presented sensitive response to luteolin. The linear determination range was 0. 01 - 5. 0. mol/L and the detection limit was 6. 0 nmol/L (S/N = 3). The sensor could be applied to the detection of luteolin in oral solution and peanut hulls, with recoveries of 91. 8% - 102. 4% and relative standard deviations (RSDs) of below 5. 6%.
