▎ 摘　　要

NOVELTY - Composite material comprises 0.1-0.12 pts. wt. metal organic framework (MOF)-gold nanorods (AuNRs) composite, where the MOFAuNRs composite is a core-shell structure composite with gold nanorods as the core and CU-BTC as the shell, and 0.03-0.05 pts. wt. carbon material. USE - The MOF-AuNRs-NG composite material is useful for simultaneous detection of dopamine, uric acid and vitamin C. ADVANTAGE - The composite material has enhanced electro-catalytic activity and electron transfer rate, capable of performing high selectivity to dopamine, uric acid and vitamin C at the same time, high sensitivity detection, and provides a new selection for the detection of the three. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a method for preparing the composite material; and a method for simultaneously detecting dopamine, uric acid and vitamin C.
