Summary: Transition-metal-catalyzed hydride-transfer reactions play a crucial role in building a sustainable energy economy, with a focus on H-2 evolution and CO2 reduction/hydrogenation catalysis. Therefore, understanding the hydricity of transition-metal hydrides and its influencing factors is essential for designing efficient catalysts.

Summary: This work aims to optimize the Ni substitution in Mg2FeH6 and form the quaternary intermetallic hydrides of Mg2Fe(1-x)NixH6 with the best kinetics and reversibility. The degree of Ni substitution is enhanced by increasing the Mg2NiH4 content, resulting in improved dehydrogenation kinetics and reversible hydrogen capacities. The structures and dehydrogenation energies of Mg2Fe(1-x)NixH6 with different Ni-substituted contents are simulated and calculated to explain the role of Ni substitution.

Summary: The study proposes a light-mediated catalytic strategy that utilizes the coupling of photothermal and catalytic effects to achieve reversible hydrogen storage. Experimental results demonstrate that complete hydrogen release is achieved within 7 minutes under light irradiation for NaAlH4 with the catalysis of TiO2@C. The strategy is also applicable to other light metal hydrides and provides an alternative approach to electric heating.

Summary: Borane-mediated hydride abstraction has been shown to be a powerful tool for the C(sp(3))-H functionalization of amines, but its activity with ethers is still unknown. In this study, we discovered this activity in 2H-chromenes and established a catalytic C(sp(3))-H functionalization reaction using silyl ketene acetals as nucleophiles.

Summary: This study shows that the dehydrogenation activation energy of MgH2 can be lowered by incorporating ceria, but the ceria undergoes phase transformations during dehydrogenation. It also suggests that reduced cerium oxide phases may be mistaken as cerium hydrides, therefore the belief in CeH2 as an active catalyst in the MgH2/CeO2 hydrogen storage system needs further scrutiny.

Summary: Increasing demand for renewable and clean energy due to environmental pollution and energy consumption has led to increased attention towards hydrogen storage materials. These materials have high safety and large volumetric density for hydrogen storage, making them suitable for large-capacity and long-term energy storage capability. Various characterization techniques have been used to understand the mechanisms of hydrogen absorption and desorption, with a recent focus on local characterization techniques to study surface and nanostructural interface effects. This article reviews the application of these characterization techniques in exploring hydrogen storage materials.

Summary: In this study, vanadium-doped NaBH4 nanocubes and the related core-shell structure (V-NaBH4@Ni) were found to significantly lower the hydrogen release temperature to 355 degrees C. The improved hydrogen release was attributed to the synergistic effects of the unique core-shell structure and the formation of intermediate borides (VxBy and NixBy) at the core-shell interface, which enhanced electron transfer and triggered hydrogen release at lower temperatures.

Summary: This study continues the computational analysis of a reactor with hexagonal honeycomb-based heat transfer enhancements, investigating the performance of a metal alloy and the reactor experimentally. It determines the gravimetric capacity and reaction kinetics of the alloy La0.9Ce0.1Ni5, while also exploring the impact of operating conditions on reactor performance. Additionally, evaporative cooling is tested for the first time as a heat removal technique for metal hydride based hydrogen storage reactors and found to significantly improve heat transfer.

Summary: Recent computational studies have successfully predicted the uptake of hydrogen by metals under pressure and the formation of superhydrides, which have been observed universally. LaH10 exemplifies the properties of these H-rich compounds, some of which are superconducting materials. Another remarkable property of superhydrides, namely H delta- superionicity, is demonstrated in LaH10. Through ab initio molecular dynamics simulations, a high hydride (H delta-) diffusion coefficient is calculated, indicating a superionic phase. The superionic phase is stable up to 2500 K with a high melting temperature, similar to pure La. The pathway for hydride ion diffusion and the clathrate structure of the H sublattice are revealed. The conductivity properties of LaH10 are discussed in relation to other compounds with fast pure hydride ion transport.

Summary: Copper guanidine quinolinyl complexes with distorted structures are good models for the entatic state, leading to high similarity between Cu(i) and Cu(ii) complexes. In this study, guanidine quinolinyl ligands with different substituents were synthesized to examine their influence on the electron transfer properties of the corresponding copper complexes. Experimental and theoretical methods were applied to study the effects of substituents on the properties of the complexes.
