Carbendazim (CBZ) is beneficial to fruit and vegetable cultivation, but its residue will cause fruit and vegetable juice pollution. In this work, an electrochemical sensor based on carbon nanohorns@reduced graphene oxide coated by gold platinum core-shell nanoparticles (Au@Pt/CNHs@RGO/GCE) was prepared for CBZ detection. The results showed that the assembly of CNHs and RGO assisted by ultrasound improved the electron transfer ability and electrochemical active surface area of CNHs@RGO. Moreover, the coating of Au@Pt nanoparticles further enhanced the sensitivity of the sensor. With the synergistic effect of the three materials, the sensor had a wider linear range (0.05 µmol/L-50 µmol/L), a lower limit of detection (1.64 nmol/L), and satisfactory recovery rates (90.60 % ∼ 97.60 %, carrot juice; 94.00-114.43 %, orange juice). Additionally, the sensor presented good anti-interference and repeatability. This work provides a simple, rapid, economical, sensitive, and accurate sensor for CBZ quantification in fruit and vegetable juice.
