“…As shown in Fig. 8, a weight loss observed at 150°C is due to the loss of water molecules, which are physically adsorbed on the surface of the catalyst [52]. The subsequent weight loss displayed at 180-290°C, which can be associated with the desorption of chemically bonded H 2 O molecules to SiO 2 .…”

In this research, meso-tetrakis(4-carboxyphenyl)porphyrinatomanganese(III) acetate has been immobilized onto the modified silica-coated Fe3O4 nanoparticles with linkers with different chain lengths (short, Fe3O4@SiO2-MnTCPP (C-1), medium Fe3O4@SiO2-NH2-MnTCPP (C-2), and long length, Fe3O4@SiO2-NHCO-NH2-MnTCPP (C-3)). The catalysts were characterized by various analytical and spectroscopic methods, including FT-IR, UV-Vis, XRD, FE-SEM, TEM, TGA, and VSM. A comparative study based on the difference in chain length of the linker in the oxidation of olefins with molecular oxygen was performed. The novel linker (long-chain catalyst) was designed to improve the performance of the catalytic activity (complete conversion of the α-methyl styrene, 4-methyl styrene and 4-chloro styrene was achieved after 2 h). The new heterogenized catalyst (Fe3O4@SiO2-NHCO-NH2-MnTCPP) not only shows higher catalytic activity in the oxidation of different olefins, but also shows better reusability of the catalyst.
