The rapid urbanization and industrialization is causing worldwide water pollution, calling for advanced cleaning methods. For instance, pollutant adsorption on magnetic oxides is efficient and very practical due to the easy separation from solutions by an magnetic field. Here we review the synthesis and performance of magnetic oxides such as iron oxides, spinel ferrites, and perovskite oxides for water remediation. We present structural, optical, and magnetic properties. Magnetic oxides are also promising photocatalysts for the degradation of organic pollutants. Antimicrobial activities and adsorption of heavy metals and radionucleides are also discussed.

“…The extracted lignin samples were analyzed via a Bruker Avance 400 MHz two-dimensional heteronuclear single quantum coherence nuclear magnetic resonance spectrometer (2D-HSQC-NMR, Billerica, MA, USA) to identify the change in structural units of lignin structure and investigate the cleavage of linkage bonds [33]. The chemical groups of lignin were analyzed through the FTIR [34]. The Waters Alliance gel permeation chromatography 1515 (Waters, USA) was used to analyze the molecular weight of lignin [35].…”

Lignocellulosic biomass is considered as the largest potential candidate to develop alternative energy, such as biofuel, biomaterial. However, the efficient conversion of cellulose and practical utilization of lignin are great challenges for sustainable biorefinery. In this study, high reducing sugar yield and different size of lignin colloid particles (LCPs) were obtained via tetrahydrofuran–water (THF–H2O) pretreatment of corn stover (CS). THF–H2O as a co-solvent, could efficiently dissolve lignin and retain cellulose. After the pretreatment, 640.87 mg/g of reducing sugar was produced, that was 6.66-fold higher than that of the untreated CS. Meanwhile, the pretreatment liquor could form spherical LCPs with different sizes ranged from 202 to 732 nm through self-assembly. We studied the optimal pretreatment condition to simultaneously realize the high reducing sugar yield (588.4 mg/g) and excellent LCPs preparation with average size of 243 nm was under TH22 (THF–H2O pretreatment at 120 °C for 2 h). To further explore the formation of LCPs with different sizes. We studied the lignin structure changes of various conditions, concluded the size of LCPs was related to the lignin concentration and syringyl/guaiacyl (S/G) ratio. As the increase of the lignin concentration and S/G, the sizes of LCPs were increased. G-type lignin was easier to dissolve in the mild pretreatment supernatant, contributing to form smaller LCPs with a good dispersibility. In the severe condition, both of S and G-type lignin were dissolved due to the lignin depolymerization, formed the larger sphere particles. This work provides a novel perspective for the technical design of lignocellulosic biomass conversion.

LaFeO3/zeolite (LFO‐Z) composite has been successfully synthesized via impregnation‐calcination method for the photo‐Fenton degradation of Tetracycline (TC). The incorporation of LaFeO3 particles on zeolite support contributes to the enhancement in photo‐Fenton catalytic activity of LFO‐Z photocatalyst by increasing the contact area between the material and TC molecules. The LFO‐Z photocatalyst was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD), N2 adsorption‐desorption, and optical absorption spectra. Different operational parameters such as catalyst dosage, H2O2 concentration, pH was investigated in the photo‐Fenton catalytic degradation of TC. 76.4 % of TC was degraded after 150 min exposure to visible light under the conditions of 1 g L‐1 LFO‐Z, 10 mg L‐1 TC, 10 mM H2O2 and pH of 6. The LFO‐Z composite shows a high stability and reusability, suggesting its potential use as a photocatalyst for pharmaceutical degradation via the photo‐Fenton process.
