Summary: To address the growing complications in energy production, a novel energetic solid composite based on nano-sized EuMnO3/EuMn2O5 incorporated with multiwalled carbon nanotube (EM/EMM/MWCNT) materials was fabricated via efficient synthesis protocols. The in-situ combustion route was used to design the interface architecture of the binary EM/EMM nanocomposites by manipulating the fuel concentration. The incorporation of MWCNT at varying concentrations improved the electrochemical hydrogen storage of the nanocomposites, with the best performance achieved at a MWCNT concentration of 3.0%.

Summary: With increased development and electricity generation, it is crucial to consider energy storage systems to overcome the discontinuity in renewable production. Hydrogen is an ideal energy carrier for future mobility, such as automotive applications. However, current hydrogen storage materials do not meet all requirements in terms of storage capacity and commercialization. Developing new materials with large surface area, homogeneous texture, active-conductive profiles, large oxygen vacancies, and low cost is crucial. Multiphase materials composed of these materials can meet the requirements in this field.

Summary: Hydrogen storage remains a huge challenge for the development of a sustainable energy system, despite its importance. Light metal hydrides have high hydrogen densities but suffer from slow kinetics and poor reversibility due to strong bonds between metal atoms and hydrogen. Nanoscale particles offer a promising solution to tailor the properties of light metal hydrides and improve their performance. This review summarizes the preparation methods and hydrogen storage performance of nanostructured light metal hydrides, discusses the challenges, and explores future research prospects, highlighting the combination of nanostructuring and nanocatalysis for practical hydrogen carriers.

Summary: The treatment of real or synthetic industrial effluents and the study of photocatalysts have attracted a lot of attention from scientists. Among various metal oxide photocatalytic materials, narrow bandgap compounds are particularly significant for their suitable efficiency in optical applications. In this study, pristine ErVO4 was synthesized using the microwave-assisted method, with different solvents and power intensities employed for size and shape control. The properties of the samples, including phase purity, surface area, magnetic and optical features, were analyzed. Microwaves with a power of 900W and ethylene glycol solvent were found to be optimal conditions for generating uniform nanosized particles. The nanostructured ErVO4 was used as a catalyst for the decolorization of colored pollutants, showing high photocatalytic efficiency in experiments with different dye concentrations and catalyst loadings.

Summary: The present study synthesized Ni-M-Tb/Al2O3 (M: Mg, Ca, Sr, and Ba) nanostructured catalysts with different ratios of alkali metals by the ultrasonic-assisted one-pot method. The catalytic performance was evaluated through H2-TPR analysis, and the structural properties were characterized by XRD, SEM, TEM, and BET equation. The 2Ni-5Mg-5Tb/Al2O3 catalyst exhibited the highest CO2 conversion of 75.37% and CH4 selectivity of 100% at 400 degrees C with a molar ratio of H2:CO2:3.5 for 100 hours, attributed to the unique electronic structure of Tb in combination with Mg and Ni, which minimized agglomeration according to SEM and BET results. These findings suggest that tuning the combination of alkali and rare earth elements as promoters in Ni-based catalysts could lead to novel catalysts with high CO2 conversion efficiency to CH4.

Summary: Innovation of photocatalysts with acceptable performance and easy recyclability through magnetic separation is a crucial challenge for researchers, as these materials have the potential to improve environmental health. Fe2O3 nanostructures were effectively loaded onto ZnS/ZnIn2S4 nanocomposites via a glycothermal process. The study investigated the impact of the amount of Fe2O3 nanostructures on the structural, physical, magnetic, and photocatalytic properties of the resulting nanocomposites. The magnetic recyclable photocatalysts exhibited a flower-shaped microstructure assembled from nanosheets. The ZnS/ZnIn2S4/Fe2O3 nanocomposites showed higher saturation magnetization than the binary ZnS/ZnIn2S4 nanocomposites. Photocatalytic decolorization experiments demonstrated high removal efficiencies for Rhodamine B and Methyl orange solutions using the ZnS/ZnIn2S4/Fe2O3 nanocomposites. Additionally, the nanocomposites could be easily separated and recycled multiple times with a degradation efficiency of 60.83%. The magnetic ZnS/ZnIn2S4/Fe2O3 nanocomposites are suitable for large-scale applications in industrial water treatment systems.

Summary: In this study, an ErMnO3/ErMn2O5/CuO/g-C3N4 nanocomposite was synthesized and used for H2 storage. The nanocomposite was prepared through in-situ synthesis of ErMnO3/ErMn2O5/CuO (NC-1), followed by the addition of g-C3N4 to prepare ErMnO3/ErMn2O5/CuO/g-C3N4 nanocomposite (NC-2). The presence of CuO did not affect the optical property of ErMnO3/ErMn2O5, while the addition of g-C3N4 increased the band gap due to particle agglomeration on ErMnO3. The magnetic properties varied in each step, with ErMnO3 exhibiting ferromagnetic behavior that changed to paramagnetic in NC-1, and ferromagnetism behavior in NC-2. Furthermore, CuO and g-C3N4 were found to enhance the H2 storage capacity of ErMnO3/ErMn2O5.

Summary: This study focuses on the hydrogen storage ability of sol-gel synthesized Ce2Y2O7 nanoribbons as active materials. The impact of different carbonous materials (such as graphene oxide, nitrogen-doped graphene quantum dots, and g-C3N4) on the hydrogen storage capacity of Ce2Y2O7 nanoribbons was compared. The carbonous nanocomposites provided were characterized using various methods to identify their phase purity, shape, and porosity. Galvanostatic charge-discharge profiles were performed for all samples to achieve optimal capacitance. The results showed that the nanocomposites of GO/Ce2Y2O7, N-GQDs/Ce2Y2O7, and g-C3N4/Ce2Y2O7 had maximum discharge capacities of 656, 686, and 757 mAhg(-1), respectively, while pristine Ce2Y2O7 nanoribbons had a discharge capacity of 643 mAhg(-1) after 15 cycles.
