“…Many research groups have found that SC can be used as a surfactant to promote the formation of spherical nanostructures. 34 Similarly, when CTAB was used instead of SDS, cheese-like In 2 O 3 with uniform size could be obtained (Figure 1g−i). The size of the generated nanocubes was about 1−2 μm, and their surface exhibited porous and cheese-like with crater defects.…”

In the field of electromagnetic wave (EMW) absorption, the development of nonmagnetic materials with strong absorptive performance, low filling ratio, and wide bandwidth is of significant importance. In this work, five morphologies of In 2 O 3 nanomaterials are prepared by simple hydrothermal and annealing processes. The morphologies of products (including the lamellar flower-, lychee-, cheese-, nanocube-, and urchin-like In 2 O 3 ) are obtained by using different surfactants. The experimental results indicate that the lamellar flower-like In 2 O 3 has a minimum reflection loss (RL min ) of −52.04 dB (1.74 mm) and an effective absorption bandwidth (EAB) of 5.97 GHz (1.92 mm). Correspondingly, the RL min and EAB of lychee-like In 2 O 3 are −70.61 dB (2.55 mm) and 5.57 GHz (1.72 mm), respectively. A large specific surface area about lamellar flower-like In 2 O 3 can effectively increase the reflection and scattering paths of EMW inside the absorbing material, which is beneficial for the attenuation of EMW. This work not only demonstrates the great potential of In 2 O 3 in practical EMW absorption applications but also extends the research on nonmagnetic materials in the EMW absorption field.

“…It could be seen from the figure that the positions and sizes of characteristic peaks of the prepared nanoparticles were consistent with those of the standard hematite cards. The diffraction peaks located at 24.1°, 33.2°, 35.6°, 40.9°, 49.5°, 54.1°, 62.4°, and 63.9°belong to (012), (104), (110), (113), (024), (116), (214) and (300) diffraction crystals, which proved the composition of the prepared nanoparticles was α-Fe 2 O 3[41,42].

The α-Fe2O3 nanoparticles were prepared via the alcohol solution combustion process of ferric nitrate. The scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) were taken to characterize the prepared α-Fe2O3 nanoparticles. The average particle sizes of the as-prepared α-Fe2O3 nanoparticles were approximately 180 nm, and their magnetic property was approximately 0.42 emu·g-1 after the measurement. The different concentrations of BSA solutions and the adsorption times were investigated to investigate the adsorption characteristics of bovine serum albumin (BSA) onto α-Fe2O3 nanoparticles. For larger adsorption capacity and higher removal rate, the dose of α-Fe2O3 nanoparticles in aqueous solution was selected at 2.5 mg·mL-1. The adsorption process of BSA onto α-Fe2O3 nanoparticles conformed to the pseudo-first-order kinetic model. While, the correlation coefficient (R2) of the Temkin isothermal model was higher than Langmuir model and Freundlich isothermal model, suggesting that the isothermal model of BSA onto α-Fe2O3 nanoparticles was more in line with Temkin isotherm model. Which suggested that the adsorption behavior of magnetic α-Fe2O3 nanoparticles for BSA belonged to multi-molecular layer chemisorption. When BSA concentration was 600 mg·L-1 and the pH of solution was 5, the adsorption capacity of BSA onto magnetic α-Fe2O3 nanoparticles achieved 114.2 mg·g-1, and the adsorption rate could still reach 70.3% of the first time after 7 cycles.
