MoS2-TiO2 Nanocomposite with Excellent Adsorption Performance and High Antibacterial Activity

摘要

The need of multifunctional advanced materials, facilitating clean and sustainable environment is the key issue from the perspective of materials scientists. This study demonstrates facile and scalable synthesis of MoS2-TiO2 nanocomposites and their excellent performance as nanoadsorbents and antibacterial agent. The synthesized composites, with different loading of MoS2 and TiO2, were examined by XRD, XPS, RAMAN, FESEM and HRTEM for structural, chemical and morphological details. The MoS2-TiO2 nanocomposite displays adsorption capacity as high as 364.56 mg g~(-1) for methylene blue (MB) at room temperature and the kinetic data reveal that the adsorption process of MB is well-matched with the pseudo-first-order model. The MoS2-TiO2 nanocomposites, with different morphology, have shown their capability as an organic dye scavenger with high speed and efficiency. Moreover the composites execute considerable antibacterial activity against Gram positive Staphylococcus aureus and Gram negative Escherichia coli bacteria. Thus the presented MoS-(2-)TiO2nanocomposite, with synergistic performance, shows huge potential in the search of multifunctional smart materials for future technology to address environment issues.
