Borohydrides, known for ultrahigh hydrogen density, are promising storage materials but typically require high operating temperatures due to their strong thermodynamic stability. Here we introduce a novel light-induced destabilization mechanism reaction of borohydrides under ambient conditions via photogenerated vacancies in LiH. These thermodynamically destabilize B–H bonds through the spontaneous "strong adsorption" BH4 groups, which trigger an asymmetric redistribution electrons, enabling release at near room temperature, approximately 300 °C lower than corresponding thermal process. By utilizing specially designed "nano-photothermal reactors", optimize effect with nanoscale dispersed LiH and create space-confined "hotspots" enhance kinetics, achieve capacity 11.02 wt % H2 LiBH4 using only light irradiation. This can also be extended other alkali metal borohydrides, offering insights developing solid-state mild conditions.

Abstract Hydrogen storage in MgH 2 is an ideal solution for realizing the safe of hydrogen. High operating temperature, however, required hydrogen induced by high thermodynamic stability and kinetic barrier. Herein, flower‐like microspheres uniformly constructed N‐doped TiO nanosheets coated with TiN nanoparticles are fabricated to integrate light absorber thermo‐chemical catalysts at a nanometer scale driving using solar energy. situ transformed into x O y Ti/TiH distributed inside matrix during cycling, which pairs serve as absorbers that exhibit strong localized surface plasmon resonance effect full‐spectrum absorbance capability. On other hand, it theoretically experimentally demonstrated intimate interface between TiH can not only thermodynamically kinetically promote H desorption from but also simultaneously weaken Ti─H bonds hence turn improve combination weakened bonds. The uniform integration photothermal catalytic leads direct action heat generated on initiating capacity 6.1 wt.% under 27 sun.

To effectively address the kinetic sluggishness associated with MgH2, this study utilized Ti-EG-Ni dual-metal organic crystal as precursors and employed carburization to prepare unique rod-shaped structure TiO2/C/Ni. The catalyst was incorporated into MgH2 by ball milling, demonstrating excellent hydrogen storage performance. composite of MgH2-8 wt % TiO2/C/Ni exhibited a lower initial dehydrogenation temperature 185 °C marked activation energy 60.537 kJ/mol. At 300 150 °C, it only required s release 6.17 H2 absorb 5.72 within 20 s, respectively. Additionally, composites demonstrated cycling stability, maintaining 94% reversible capacity after 50 cycles. Theoretical computations suggested that in situ-generated metal Mg2Ni semiconductor TiO2 created Schottky heterojunction, which stimulated an internal electric field between Ni TiO2, accelerating electron transfer. strong electronic interaction weakened Mg-H bond elongated bond, promoting dissociation. During absorption desorption, material performance due uniform distribution elements, catalytic active sites (multivalent Ti Mg2Ni/Mg2NiH4), support provided carbon nanostructures. Our findings provide deeper understanding how highly catalysts oxides/C/Ni enhance MgH2.
