Magnesium hydride owns the largest share of publications on solid materials for hydrogen storage. The group international experts contributing to IEA Task 32 Hydrogen Based Energy Storage recently published two review papers presenting activities focused magnesium based and Mg compounds energy This article not only overviews latest both fundamental aspects Mg-based hydrides their applications, but also presents a historic overview topic outlines projected future developments. Particular...
Liquid hydrogen carriers are considered to be attractive storage options because of their ease integration into existing chemical transportation infrastructures when compared with liquid or compressed hydrogen. The development such forms part the work International Energy Agency Task 32: Hydrogen-Based Storage. Here, we report state-of-the-art for ammonia-based and organic carriers, a particular focus on challenge ensuring easily regenerable, high-density storage.
Development of non-noble metal catalysts with similar activity and stability to noble metals is significant importance in the conversion utilization clean energies.

Light harvesting, separation of charge carriers, and surface reactions are three fundamental steps that essential for an efficient photocatalyst. Here we show these in the TiO2 can be boosted simultaneously by disorder engineering. A solid-state reduction reaction between sodium forms a core-shell c-TiO2@a-TiO2-x(OH)y heterostructure, comprised HO-Ti-[O]-Ti frustrated Lewis pairs (SFLPs) embedded amorphous shell surrounding crystalline core, which enables new genre chemical reactivity....
Industrial ammonia synthesis catalyzed by Fe- and Ru-based catalysts is an energy-consuming process. The development of low-temperature active catalyst has been pursued for a century. Herein, we report that barium hydride (BaH2) can synergize with Co, leading to much better activity, i.e., the BaH2-Co/carbon nanotube (CNT) exhibits activity right above 150 °C; at 300 °C, it 2 orders magnitude higher than BaO-Co/CNTs more 2.5-times Cs-promoted Ru/MgO. Kinetic analyses reveal dissociative...

It observed that approximately 1 equiv. of hydrogen evolved from the doped borane samples at a temperature as low 59 °C. Moreover, catalytic dehydrogenation did not present any induction period, undesirable byproduct borazine, or sample forming. Electron paramagnetic resonance (EPR) characterization revealed Co in partially reduced state is active species

Lack of efficient hydrogen storage method is one the technical bottlenecks for implementation energy. Liquid organic carriers (LOHCs), especially N-heterocycles, have been considered as potential candidates both on-board and off-board owing to their low cost, high gravimetric capacity, reversibility, compatibility with existing infrastructures minimal modification. LOHCs however encounter severe kinetic barriers in uptake release processes, thus catalysts are critically needed. Much...
