Efficient photocatalytic dye degradation by flowerlike MoS2/SrFe12O19 heterojunction under visible light

Application of Spinel and Hexagonal Ferrites in Heterogeneous Photocatalysis

“…The slight activity loss was observed during recycling, i.e., 90% degradation after four 30 min cycles (but still almost 100% for a 1 h process). In another study, Chen et al prepared a SrFe12O19/MoS2 heterostructure as the visiblelight active photocatalysts for MB and methyl orange (MO) degradation under simulated sunlight [137]. The highest activity was observed for the composite with 1:2 mass ratio of Sr-ferrite:MoS2, reaching ca.…”

“…This leads to confusing results reported in different studies. For example, opposite charge transfers between the same components was claimed (e.g., BaFe 12 O 19 /g-C 3 N 4 [122,123]) or the oxidative role of • OH radicals in the presence of Ba-ferrite [78,81] was suggested, whereas other studies excluded such mechanisms [131,137]. Since water purification from organic pollutants remains the most investigated application of the magnetic photocatalysts, these details, as well as the possible factors that affect them, are considered as crucial for further studies to better understand the interactions between hexaferrites, other photocatalysts, and pollutants.…”

Synergistic effect of GO/SrFe12O19 as magnetic hybrid nanocatalyst for regioselective ring-opening of epoxides with amines under eco-friendly conditions

“…[7][8][9][10][11][12] Among the interesting nanomaterials, hexagonal ferrites represent important classes of magnetic materials in diverse areas of applications such as plastic magnets, permanent magnets, recording media, microwave components, high-frequency devices, and catalysts or photocatalysts. [13][14][15][16] Since their discovery in the 1950s there has been an increasing degree of interest in the hexagonal ferrites, 17 and their synthesis and study deserve a particular interest for R&D researchers. 16,[18][19][20] However, magnetic nanoparticles (MNPs) have gained the attention of many scientists due to their excellent physical and chemical properties compared to traditional bulk materials, such as superparamagnetism, high surface area, high surfaceto-volume ratio, simple separation under external magnetic elds, and high adsorption capacity.…”

[21][22][23][24][25][26] Nowadays, it has been found that the dispersion of magnetic NPs on 2D materials such as graphene sheets is potentially turning into a new research topic due to their improved functionalities.…”
