摘要：

Electrochemically FeS2 thin films have been synthesized on ITO substrates at room temperature (25 degrees C). UV-Vis, X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM) were used for the characterization of nanostructure FeS2 thin films. Two probe I-V measurements convey that the material is p type and a p-n junction (diode) was found to be developed between FeS2 and ITO layer. Cyclic voltametry study shows that FeS2/ITO electrode facilitates the reduction of hydrogen peroxide and exhibits excellent electro-catalytic activity towards its sensing. Photocatalytic study reveals that the synthesized thin films are also efficient to degrade terephthalic acid (TA). (C) 2015 Elsevier B.V. All rights reserved.
