“…MgCl 2 concentrations of 1 mM, 2 mM, 3 mM, 4 mM, and 5 mM were investigated, keeping the glucose concentration constant at 10 mM. To facilitate the formation of the C/MgO complex, the established hydrothermal method was utilized [ 28 ]. Thus, the mixture was transferred into a cylindrical stainless-steel vial, equipped with a Teflon liner to prevent sample contamination from reactions with the stainless-steel interior.…”

A composite material composed of anodized aluminum oxide (AAO), carbon (C), and magnesium oxide (MgO) was developed for CO2 capture applications. Inspired by the bryophyte organism, the AAO/C/MgO composite mirrors two primary features of these species—(1) morphological characteristics and (2) elemental composition—specifically carbon, oxygen, and magnesium. The synthesis process involved two sequential steps: electroanodization of aluminum foil followed by a hydrothermal method using a mixture of glucose and magnesium chloride (MgCl2). The concentration of MgCl2 was systematically varied as the sole experimental variable across five levels—1 mM, 2 mM, 3 mM, 4 mM, and 5 mM—to investigate the impact of MgO formation on the samples’ chemical and physical properties, and consequently, their CO2 capture efficiency. Thus, scanning electron microscopy analysis revealed the AAO substrate’s porous structure, with pore diameters measuring 250 ± 30 nm. The growth of MgO on the AAO substrate resulted in spherical structures, whose diameter expanded from 15 nm ± 3 nm to 1000 nm ± 250 nm with increasing MgCl2 concentration from the minor to major concentrations explored, respectively. X-ray photoelectron spectroscopy (XPS) analysis indicated that carbon serves as a linking agent between AAO and MgO within the composite. Notably, the composite synthesized with a 4 mM MgCl2 concentration exhibited the highest CO2 capture efficiency, as determined by UV-Vis absorbance studies using a sodium carbonate solution as the CO2 source. This efficiency was quantified with a ‘k’ constant of 0.10531, significantly higher than those of other studied samples. The superior performance of the 4 mM MgCl2 sample in CO2 capture is likely due to the optimal density of MgO structures formed on the sample’s surface, enhancing its adsorptive capabilities as suggested by the XPS results.

“…The core–shell nanostructure has been getting much attention in research trends due to its fascinating material properties, which were applied in boundless fields not only for energy applications but also for water treatment, dye removal, therapeutic applications, etc . The current synthesis techniques such as the solvo/hydrothermal method, − thermal decomposition method, and template methods instruct to follow the controlled reaction environment of high temperature and extent period. So, the development of a simple but rapid formation of narrowly distributed manganese ferrites under economic synthesis is currently needed.…”

With the considerations of attaining high-capacity anode material for longer cycles at a high charge−discharge rate, in this work, a facile core−shell manganese ferrite/reduced graphene oxide (CSMF/rGO) was fabricated in situ through a rapid two-step ultrasonication method. For that, the CSMF was synthesized by adopting a simple but effective electrochemical method with ultrasound assistance. The prepared three-dimensional network of CSMF was incorporated into the self-assembled graphene matrix by in situultrasonication to form a hybrid nanoarchitectonic composite (CSMF/rGO). The coupled effect of redox reactions and ultrasonic cavitation for the formation of CSMF/rGO were discussed. The self-assembled hybrid nanoarchitectonic structure has the beneficial features of tight-packing configuration, which resolves the volume expansion−contraction nature of magnetite and simultaneously provides improvement for the movement of lithium ions and electrons during charge−discharge cycles. As a result, the CSMF/rGO electrode delivers a high initial discharge capacity of 1512 mAh g −1 at 0.2 A g −1 current density and provides a better reversible capacity of 492 mAh g −1 at a high-current density of 2.0 A g −1 after 500 cycles with high Coulombic efficiency (>99%). The results of this report would be helpful to design a CSMF/rGO hybrid electrode as a new-gen anode for the utilization of lithium-ion batteries under an economic and rapid synthesis method.
