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

Antimony sulfide (Sb2S3) 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 Sb2S3 films were characterized by XRD, SEM, TEM and electrochemical workstation. The results show Sb2S3 films mainly consist of orthorhombic phase with micro-nanorods morphology. Sb2S3 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 Sb2S3 films as a promising candidate for potential application in the field of catalysis and environmental.
