Algal biochar reinforced trimetallic nanocomposite as adsorptional/photocatalyst for remediation of malachite green from aqueous medium

摘要

The algal biochar reinforced trimetallic nanocomposite (AlBc TNC) was fabricated by employing facile greener microwave technique. AlBcTNC was explored as a promising adsorbent/photocatalyst designed for the exclusion of malachite green (MG). The prepared AlBcTNC was examined by X-Ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM), X-Ray diffraction (XRD), Transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). The investigational outcomes disclosed that the fabricated AlBcTNC has good adsorptional/photocatalytic potential towards the remediation of MG. 94% of MG dye was remediated using the adsorptional/photocatalytic process. The detail photo-degradation mechanism was inspected by analysing the degradation intermediates using LC-MS technique. (C) 2018 Elsevier B.V. All rights reserved.
