Summary: This study investigates the improvement of hydrogen storage properties of MgH2 by using activated carbon as a catalyst in MgH2-AC nanocomposites. The results show that the presence of activated carbon helps reduce oxygen in MgO phase, leading to significantly enhanced absorption capacity and kinetics in the MgH2-AC nanocomposites. The nanocomposites also exhibit high hydrogenation properties with the presence of beta- and gamma-phases of MgH2, as supported by XRD data.

Summary: A high-energy ball milling method was used to synthesize nanocrystalline MgH2 powder samples catalyzed by Fe2Ti with different milling times (1 h, 3 h, and 10 h). The morphology and microstructure of the powders were characterized by scanning electron microscopy and X-ray diffraction. The diffraction profiles were analyzed using a convolutional multiple whole profile fitting algorithm to determine microstructural parameters of the composites. The dehydrogenation characteristics of the alloys were investigated using differential scanning calorimetry. An optimal milling time of 3 h was found to result in desorption at the lowest temperature. X-ray diffraction of partially dehydrided states confirmed a two-step H-release. The effect of milling time on the hydrogenation performance was evaluated using a Sievert-type apparatus, and the composite milled for 3 h exhibited the best overall performance.

Summary: High thermal stability and sluggish absorption/desorption kinetics are limitations for using MgH2 as a hydrogen storage medium. Introducing a suitable catalyst, such as the novel nanoparticulate ZrNi, can significantly improve the hydrogen storage properties. The catalytic reaction of nano-ZrNi during the first de-/hydrogenation cycle forms active species that enhance the breaking and rebonding of H-H bonds and provide multiple hydrogen diffusion channels, leading to remarkably improved hydrogen absorption and desorption capabilities.

Summary: In recent studies, it was found that high energy ball milling of Mg/MgH2 mixed with additives can reduce the temperature for H-2 absorption/desorption without altering thermodynamic properties. This research aimed to identify efficient hydrogen absorption/desorption catalysts at low temperatures, particularly at room temperature (RT). Among the additives tested in this study, MgH2-TiFe mixture showed the best performance, attributed to the strong catalytic action of TiFe and the high energy interfaces attracting hydrogen gas.

Summary: By introducing nitrogen anions, a N-doped K2Ti6O13 (N-KTiO) catalyst with reduced band gap was obtained, which improved the kinetics and cycling stability of the Mg/MgH2 system. The peak temperature of MgH2 with 5 wt% N-KTiO was significantly lower than those of TiO2 catalysed and pure ones, and it absorbed 4.6 wt% H2 in 1 hour even at room temperature. After cycling for 200 times at 300 degrees C, the H2 capacity remained at 6.8 wt% with a retention as high as 94.4%. The research provides insights for developing effective catalysts for light metal hydrogen storage materials.

Summary: A novel nanocomposite (0.2TiO(2) + AC) with two promising applications is demonstrated, as an additive for promoting hydrogen storage in magnesium hydride and as an active electrode material for hosting lithium in Li ion batteries. Transmission electron microscopy study provides evidence that well dispersed TiO2 nanoparticles are enclosed by amorphous carbon nets. The nanocomposite is thermally stable up to similar to 400 degrees C according to a thermogravimetry-differential scanning calorimetry (TG-DSC) study. Volumetric hydrogen storage tests and DSC studies further prove that a 3 wt% of 0.2TiO(2) + AC nanocomposite as additive lowers the dehydrogenation temperature of MgH2 over 100 degrees C and maintains the performance consistency. As a working electrode for Li ion battery, 0.2TiO(2)+AC offers a reversible capacity of 400 mAh/g at the charge/discharge rate of 0.1C and consistent stability up to 43 cycles with the capacity retention of 160 mAh/g at 0.4C. These cost-effective high-performance materials with applications in two promising areas of energy storage are highly desired for progressing towards sustainable energy development.
