Heterojunction of TiO 2 nanoparticle embedded into ZSM5 to 2D and 3D layered-structures of MoS 2 nanosheets fabricated by pulsed laser ablation and microwave technique in deionized water: structurally enhanced photocatalytic performance. Balati, A., Wagle, D., Nash, K. L., & Shipley, H. J. Applied Nanoscience (Switzerland), 9(1):19–32, February, 2019. Publisher: Springer Naturedoi abstract bibtex In this paper, we report a one-step, fast and ecofriendly synthesis of layered-structured MoS 2 nanosheets (NSs) by pulsed laser ablation in liquids (PLAL). The resultant MoS 2 NS was used to construct TiO 2 –ZSM5–MoS 2 nanocomposite. After impregnating ZSM5 structures with TiO 2 nanoparticles (TiO 2 NPs), heterojunctions of MoS 2 NS were made on the fabricated TiO 2 –ZSM5 by microwave treatment at high temperature and pressure. Formation of 2D and 3D structures of MoS 2 was shown. Crystal structure, size and shape of the synthesized nanostructures were studied by X-ray powder diffraction (XRD) and microscopy techniques. Results of the structural analysis showed that the PLAL constructed MoS 2 NSs mainly had a layered morphology several micrometers in size with horizontally and vertically aligned layers. The hexagonal crystalline structure of MoS 2 NS, anatase TiO 2 NPs and microcrystalline ZSM5 structures were determined by XRD, high-resolution transmission electron microscopy (HRTEM) and fast Fourier transform (FFT) analysis. Formation of MoS 2 NS was further shown with Raman peaks at approximately 385.30 and 407.50 cm −1 corresponding to the E1 2 g and A1g vibrational modes of MoS 2 NS. The PLAL synthesized MoS 2 NS demonstrated broad absorption in the visible region. Photocatalytic activity of TiO 2 –ZSM5–MoS 2 nanocomposite was tested with arsenite. TiO 2 –ZSM5–MoS 2 nanocomposite exhibited approximately 100% arsenite photo-conversion to arsenate.
