Facile synthesis and hydrazine detection activity of Sb2S3 films on indium tin oxide electrode

Abstract Antimony sulfide (Sb 2 S 3 ) films on indium tin oxide (ITO) glass substrates were prepared by electrodeposition method followed with heat-treatment process using a thiol–amine as solvent mixture under ambient conditions. The structure and properties of the Sb 2 S 3 films were characterized by XRD, SEM, TEM and electrochemical workstation. The results show Sb 2 S 3 films mainly consist of orthorhombic phase with micro-nanorods morphology. Sb 2 S 3 films exhibit good electrocatalytic activity towards hydrazine oxidation with a low detection limit of 0.4 μM. The facile synthesis method and excellent sensing properties make the Sb 2 S 3 films as a promising candidate for potential application in the field of catalysis and environmental.
