摘要：
In our paper, a promising electrochemical sensing platform was fabricated with titanium carbide (Ti3C2Tx), poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and ruthenium nanoparticles (RuNPs). First, the Shandong pancake structural PEDOT:PSS/Ti3C2Tx was prepared by physical stirring. PEDOT:PSS as the dispersant was embedded into the Ti3C2Tx nanosheets, increasing the degree of dispersion of the Ti3C2Tx nanosheets and further improving the specific surface area of the composite material. Then, RuNPs were supported on the surface of PEDOT:PSS/Ti3C2Tx to form the hierarchical ternary nanocomposite of Ru/PEDOT:PSS/Ti3C2Tx. The prepared Ru/PEDOT:PSS/Ti3C2Tx nanocomposite exhibited promising electrochemical sensing properties toward Sudan I detection with a wide detection range of 0.01 similar to 100 mu M and a high sensitivity of 482.43 mu A mM(-1) cm(-2). Moreover, the Ru/PEDOT:PSS/Ti3C2Tx sensing platform has been successfully applied for Sudan I detection in ketchup and chili paste, implying the promising application prospect of Ru/PEDOT:PSS/Ti3C2Tx in food safety testing.
