Facile preparation of antimony sulfide and 3,4,9,10-perylenetetracarboxylic diimide composite nanomaterials modified fluorine-doped tin oxide glass for efficient detection of hydrazine

A novel heterojunctions of 3,4,9,10-perylenetetracarboxylic diimide (PTCDI) nanosheets coupled with antimony sulfide (Sb2S3) nanorods were synthesized by two-step electrodeposition. The addition of the inorganic nano-material Sb2S3 significantly improved the stability of the PTCDI organic nanomaterial, which already had excellent sensing properties for hydrazine. At the same time, the two materials formed a heterojunction to improve the efficiency of electron transfer when the composite electrode was used to detect hydrazine. The sensor's response current generated by the electrochemical reaction displayed that the PTCDI/Sb2S3 composite nanomaterials hold high electrocatalytic performance. The results exhibited that the obtained sensor had outstanding analytical performance according to the detection limit (13.95 +/- 0.16 nmol.L-1), sensitivity (0.1678 mu A.mol(-1).L.cm(-2), 0.1103 mu A.mu mol(-1).L.cm(-)(2)).
