Optical and Surface Studies of MoS2 Sheets functionalized with Zincon

Richa Sharma and Ashima Bagaria


Past research over elements has concluded a noteworthy role of zinc in prostate cancer. Healthy prostate has a higher amount of zinc present whereas, during prostate malignancy, the zinc concentration reduces. It has been also observed that in electrochemical sensing, hydrogen and zinc both get reduced at about the same potential (-1.2V) causing interference between them. Exploring this interference and reduction we intended to develop a platform that could modify the surface of electrodes. For this purpose, MoS2 sheets having a dimension of 0.5-0.8 μm were synthesized through the hydrothermal method and subsequently chemically functionalized with Zincon. Further MoS2-Zincon complex was analyzed via FTIR, FESEM and UV-Vis, which confirmed the formation of MoS2 – Zincon complex. In UV analysis of Zincon, the peak at 300 nm was found to be blue and shifted towards 298 nm after the formation of the complex also Zincon peaks at 528 nm was red – shifted to 557 nm after could be recognized bonding of Zincon with MoS2. FESEM images clearly showed that the flowers like structure of Zincon were distributed over MoS2 sheet. FTIR absorption band at 1102 cm-1 and 753 cm-1 contributed to =C-H from Zincon and their disappearance after Zincon complexed with MoS2 sheet confirmed the formation of the MoS2 – Zincon complex.
