In the past few years, three‐dimensional self‐supporting porous magnetic assemblies (3D‐SPMAs) have emerged as a new research area in materials science because of their combined features of three‐dimensional self‐supporting porous assemblies (3D‐SPAs) and magnetic materials. Due to these attributes, 3D‐SPMAs gain numerous tempting properties such as magnetism‐induced actuating, magnetic shape memory effects, and alternative magnetic field (AMF) induced heat generation, showcasing huge potential in diverse applications stretching over water remediation, actuators, biomedical therapy, etc. Especially, 3D‐SPMAs displayed eminent potential in water remediation for their large processing capacity, remote controllability, and magnetic‐field‐mediated wettability. With the rising interest in 3D‐SPAs, the increasing understanding of magnetic materials, and the flourish of materials preparation technique, an upsurge has appeared in 3D‐SPMAs and thus managing them a class of emerging and promising functional materials. However, currently there are rarely review papers concerning 3D‐SPMAs. In this light, this review aims to express a comprehensive overview of this young field and fuel further innovations for preparation methods and practical applications of 3D‐SPMAs. The focus is placed on the synthetic strategies and applications especially in water remediation. The potential opportunities and challenges are also discussed.

Nanostructured barium doped bismuth ferrite, Bi 0.8 Ba 0.2 FeO 3 porous ceramics with a relatively high magnetic coercivity was fabricated via sacrificial pore former method. X-ray diffraction results showed that 20 wt.% Ba doping induces a structural phase transition from rhombohedral to distorted pseudo-cubic structure in the final porous samples. Moreover, utilizing Bi 0.8 Ba 0.2 FeO 3 as the starting powder reduces the destructive interactions between the matrix phase and pore former, leading to an increase in stability of bismuth ferrite phase in the final porous ceramics. Urea-derived Bi 0.8 Ba 0.2 FeO 3 porous ceramic exhibits density of 4.74 g/cm 3 and porosity of 45 % owing the uniform distribution of interconnected pores with a mean pore size of 7.5 µm. Well defined nanostructured cell walls with a mean grain size of 90 nm were observed in the above sample, which is in a good accordance with the grain size obtained from BET measurements. Saturation magnetization decreased from 2.31 in the Bi 0.8 Ba 0.2 FeO 3 compact sample to 1.85 A·m 2 /kg in urea-derived Bi 0.8 Ba 0.2 FeO 3 porous sample; moreover, coercivity increased from 284 to 380 kA/m.

“…The enhancement of magnetic properties such as saturated magnetization (Ms), remanence (Mr), and coercive force (Hc) become major interest to be investigated. An effect of the various processes [1] and designing crystal structure of the barium ferrite to magnetic properties were investigated systematically [2][3][4][5]. In order to improve the magnetic properties, the nanocrystalline BaFe 12 O 19 ferrites has potential opportunity to be developed.…”

Abstractwere prepared by solid state reaction method. The crystal structure, microstructure, and magnetic properties were characterized using powder X-ray diffraction, scanning electron microscope (SEM) and permagraph meter, respectively. The results show that the nanocrystalline BaFe 12−2 Co Ti O 19 has single phase with polycrystalline structure, the grain size decrease by doping, the coercivity (Hc) and saturation magnetization (Ms) decrease with increasing Co-Ti substitutions.
