Iron-copper bimetallic nanoparticles embedded within ordered mesoporous carbon as effective and stable heterogeneous Fenton catalyst for the degradation of organic contaminants

Selective Catalytic Reduction of NO over Cu-Mn/OMC Catalysts: Effect of Preparation Method

“…In addition, the diffraction peaks of Cu-Mn/OMC(S) corresponding to Cu and Cu 2 O were weaker than that in other samples, which could be attributed to the better dispersion of Cu phases (Sultana et al, 2012). (Wang et al, 2015). The agglomeration of metal oxides may have destroyed the ordering of pore structure on the surface, which was consistent with the SAXRD results shown in Fig.…”

“…TEM images depicted in Fig. 3 show strip-like and hexagonally arranged patterns in large domains, which confirmed the preservation of 2-D hexagonal mesoporous structure (p6mm) after metal loading (Wang et al, 2015). For Cu-Mn/OMC(S) in Fig.…”

“…, and the narrow pore size distribution associate with controllable morphology can promote mass transfer, which are also highly desired for catalysis applications Florent et al, 2013;Wang et al, 2015). Great efforts have been made to modify the structure and properties of OMC, and transitional metal oxides (MnO x Su et al, 2013), CuO x (Ouzzine et al, 2008;Amanpour et al, 2013;Chen et al, 2014), CeO x (Shen et al, 2013;Zhang et al, 2013), FeO x Zhang and Qu, 2015), etc.)…”

Interfacial mechanisms of heterogeneous Fenton reactions catalyzed by iron-based materials: A review

“…(3) Three primary issues, i.e., the degradation efficiency, the reactivity and stability of the catalyst, and the efficiency of H 2 O 2 utilization, should be considered simultaneously in designing and applying heterogeneous Fenton systems. Since the pure iron (hydr)oxides suffer from relatively low catalytic reactivity or serious iron leaching, a supported multimetallic iron-based material (e.g., FeCu/HMS (Wang et al, 2015a), CuFe-MC (Wang et al, 2015b), MgO@Fe 2 O 3 / KIT-6 (Zheng et al, 2015)) may possess the advantage of low H 2 O 2 consumption, high catalytic reactivity and good structural stability, thus providing a promising heterogeneous Fenton catalyst. (4) As for industrial applications, other treatment processes, such as filtration and biological treatment (Melero et al, 2009;Zhang et al, 2011), can be coupled to achieve the recycling of catalysts and complete mineralization of organics.…”

Enhanced Fenton-like degradation of refractory organic compounds by surface complex formation of LaFeO3 and H2O2

“…9B), which implied that the formation of LaFeO 3 -H 2 O 2 complex was essential and stable for the Fenton reaction process. [30][31][32], a heterogeneous Fenton catalytic mechanism of LaFeO 3 was proposed as follows:…”
