Abstract: In this study, we designed a novel photoelectrochemical (PEC) sensor for thiamphenicol (TAP), which based on porous graphene (P-r-GO), MoS2 nanoflower, dendritic Pt-Pd NPs (Pt-Pd NPs), amino multiwalled carbon nanotubes (NH2-MWCNTs), molecularly imprinted polymer (MIP) and L-shape glassy carbon electrode (L-GCE). Firstly, MoS2 and P-r-GO nanoflower composite was prepared by one-step hydrothermal method. Then, this composite suspension was coated on L-GCE surface to virtually form a porous interface. After that, the suspension of Pt-Pd NPs and NH2-MWCNTs was dropped onto MoS2-P-r-GO / L-GCE. Subsequently, TAP was imprinted on above modified electrode by cyclic voltammetry as o-phenylenediamine was monomer. Afterwards, ascorbic acid was selected as a photocurrent probe when TAP was removed from MIP film and adsorbed on sensing surface. The resulting PEC sensor possessed excellent response for TAP, and its linear range was 1.0 x 10-9 ~ 3.5 x 10-6 mol L-1 with the detection limit of 5.0 x 10-10 mol L-1 . This sensor was used to determine TAP in real food samples with favorable results.
