Novel photo-Fenton nanocomposite catalyst based on waste iron chips-Ti3C2T MXene for efficient water decontamination
Abstract
The Ti3C2Tx MXene is a novel two-dimensional (2D) material with unique optical properties and excellent waterdispersibility related to rich surface termination. This study uses its properties to design an innovative magneticcatalyst made of waste iron chips (WI), surface-modified with a 2D Ti3C2Tx MXene. We further utilize it toadvance a heterogeneous Fenton process for industrial dye removal. Novel WI-MXene nanocomposite catalystovercame difficulties associated with the acidic pH range, frequently required for efficient generation of reactiveoxygen species (ROS) via Fe (II) activity. The photo-active 2D MXene enabled the WI-MXene catalyst activationin the visible light range and near-neutral pH with excellent performance in decomposing model organic dye -methylene blue (MB). The novel catalyst showed over 95 % efficiency in decomposing MB upon UV light irradiationat pH = 5 and about 62 % in decomposing the total organic carbon (TOC). Since the WI-MXene had aband gap of about 1 eV, it also showed a tunable activity toward specific light ranges. The irradiation with 550nm (cyan) light gave the highest photo-Fenton efficiency. Analysis of the fundamental process mechanismshowed a massive ROS evolution and a minor adsorption activity of WI-MXene toward decomposed dye. Thepost-process stability analysis did not show any changes in the WI-MXene structure. Further regeneration ofspent WI-MXene enabled its reuse with 90 % efficiency at various pH values. Collectively, the obtained resultsshow a high potential for MXene-enabled photo-Fenton processes.
