Preparation of magnetic silica supported Brønsted acidic ionic liquids for the depolymerization of lignin to aromatic monomers

“…4, the absorption peak at 586 cm −1 is attributed to the Fe–O bond stretching vibration of Fe 3 O 4 . 36 The characteristic peaks at 457, 802, and 1088 cm −1 correspond to the bending vibration, symmetric stretching vibration, and asymmetric stretching vibration of Si–O–Si, respectively, which indicates that silica has been coated on the surface of Fe 3 O 4 . 38 The presence of Si–OH bond stretching vibration is confirmed by the 966 cm −1 band in the FT-IR spectra of Fe 3 O 4 @ SiO 2 , while the disappearance of this absorption peak at 966 cm −1 in that of BAIL (30 wt%)–Fe 3 O 4 @ SiO 2 and recovered BAIL (30 wt%)–Fe 3 O 4 @ SiO 2 indicates that CPMS was grafted onto the carrier.…”

“…3(d) can be assigned to the (311) plane of Fe 3 O 4 , which are matched well with the results of XRD patterns, indicating the presence of Fe 3 O 4 . 36,37…”

Photocatalytic Degradation of Antibiotics via Exploitation of a Magnetic Nanocomposite: A Green Nanotechnology Approach toward Drug-Contaminated Wastewater Reclamation

“…Drug degradation initially increases due to the higher driving force facilitating the transfer of the molecules of the drug to catalyst surfaces and active sites. After this period, the degradation rate decreases due to the reduction of the remaining active catalyst sites and the long-range diffusion effect of the molecules of the drug Figure quantitatively shows the percentage degradation of CIP and AMX upon exposure.…”

Preparation of miscible CdS and homojunction C3N4 hybrids for efficient photocatalytic degradation of tetracycline

“…Solar-driven photocatalytic degradation of organic pollutants is considered a promising solution for environmental crisis. [1][2][3] The design and fabrication of efficient photocatalysts is the most effective approach to improve the photodegradation activity of organic pollutants for practical applications. 4 To date, numerous semiconductor photocatalysts have been synthesized and discussed.…”
