▎ 摘　　要

NOVELTY - Preparing boron-sulfur co-doped graphene, comprises taking graphene oxide into water for ultrasonic treatment to make graphene oxide dispersed uniformly, adding boron oxide to the uniformly dispersing the graphene for ultrasonic treatment, adding sodium sulfide for ultrasonic treatment, uniformly dispersing the boron oxide and sodium sulfide in the graphene oxide solution, placing the mixed solution into a microwave digestion apparatus, and reacting at 180-250 degrees C for 2-4 hours. USE - The boron-sulfur co-doped graphene is useful in preparing boron-sulfur co-doped graphene supported gold platinum core-shell nano-rod complex material as electrochemical immunosensor for preparing and detecting aflatoxin B1 (all claimed). ADVANTAGE - The grapheme: has excellent conductivity, large specific surface area which provides excellent interface for loading of gold@ platinum nanorods; and improves the electron transfer ability on electrode surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for boron-sulfur co-doped grapheme prepared by the above mentioned method.
