Fe–Mn/MCM-41: Preparation, Characterization, and Catalytic Activity for Methyl Orange in the Process of Heterogeneous Fenton Reaction

Degradation of mixed dye via heterogeneous Fenton process: Studies of calcination, toxicity evaluation, and kinetics

“…According to the previous research, significant results were found at pH 3 due to formation of more hydroxyl radicals (Zhang et al, 2018). But here, the maximum degradation obtained was of 99.82% at pH of 5 only in 10 min because the higher oxidizing agent was produced at pH 5 (Hassan & Wan, 2012) and it is completely based on the support used for catalyst preparation (Tiya-Djowe et al, 2018).…”

“…They found that Fe-SBA-15 catalyst significantly degraded the phenolic compounds present in aqueous solution (Tiya-Djowe et al, 2018). Zhang, Dong, Hao, Cai, and Wang (2018) investigated the degradation of methyl orange via nanocomposite material (Fe-Mn/MCM41), which was synthesized by hydrothermal followed by impregnation method. 100% methyl orange degradation and 60% total organic carbon (TOC) removal were obtained by heterogeneous Fenton catalytic process within 2 hr of successful reaction.…”

The preparation of a novel iron/manganese binary oxide for the efficient removal of hexavalent chromium [Cr(vi)] from aqueous solutions

“…[25][26][27] Hence, it is necessary to prepare an adsorbent with high adsorption capacity and propose the possible adsorption mechanism via characterization, adsorption performance, adsorption isotherm and adsorption kinetics. [28][29][30][31][32] Herein, a novel Fe-Mn binary oxide adsorbent was prepared via a "two-step method" combined with the co-precipitation method and hydrothermal method, and the adsorbent was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fouriertransform infrared spectra (FTIR), thermogravimetric analysis (TGA), zeta potential, BET and X-ray photoelectron spectroscopy (XPS). The removal of CrO 4…”

Sonochemical synthesis of library benzodiazepines using highly efficient molecular ionic liquid supported on Fe‐MCM‐41 nanocomposites as a recyclable catalyst

“…Also, the introduction of metal ingredient to MCM‐41 leads to catalyst properties enhancement, which is beneficial to organic reaction. In comparison to other metals, impregnation of iron species into MCM‐41 is significant benefits for the use of this metal in catalysis because of Lewis acidity, cheap, low in toxicity, easily accessible, and stability of Fe (III) metal (Fe‐MCM‐41) . On the other hands, various organic groups of functionalizing the surfaces of MCM‐41 have been investigated recently because surface modification provides rising of the surface properties for many potential applications including catalysis .…”

“…In comparison to other metals, impregnation of iron species into MCM-41 is significant benefits for the use of this metal in catalysis because of Lewis acidity, cheap, low in toxicity, easily accessible, and stability of Fe (III) metal (Fe-MCM-41). [8][9][10][11][12] On the other hands, various organic groups of functionalizing the surfaces of MCM-41 have been investigated recently because surface modification provides rising of the surface properties for many potential applications including catalysis. [13][14][15][16] The latest developments in supported ionic liquid systems have mainly focused on catalytic applications by functionalized ionic liquid onto the surface of MCM-41 framework (MCM-41-IL).…”
