Free-standing SiO2/TiO2-MoS2 composite nanofibrous membranes as nanoadsorbent for efficient Pb(II) removal

Abstract

Recently concerns regarding improper disposal of heavy metals have been considerably increased due to their deleterious effects to the human health and environment. Therefore, designing appropriate materials capable to remove metal ions from wastewater has become imperative. Herein, we report on the use of flexible free-standing SiO2/TiO2 nanofibrous membranes (NFMs) functionalized with MoS2 for Pb(II) removal. The proposed hybrid nanomaterial was characterized using field-emission gun scanning electron microscopy (FEG-SEM), transmission electron microscopy (TEM), energy- dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). Benefiting from the large specific surface area, high porosity, and the interaction between sulfur and lead, the NFMs could decontaminate water samples with good removal efficiency and recyclability. These excellent performances endow the nanofibrous membranes for applications for wastewater treatment.
