Summary: In this study, a two-dimensional Ti3CN MXene was synthesized and added to the Li-Mg-B-H composite, resulting in a reduction in the dehydrogenation temperature and induction period of the composite. The reversible capacity and capacity retention ratio of the composite were maintained at high levels. Micro-structure studies revealed the transformation of Ti3CN into highly-dispersed nano-TiB2, which acted as an active catalyst to improve the kinetics and reversibility of the composite. This research provides insights into the role of MXene in tailoring the hydrogen storage properties of metal borohydride-based composites.

Summary: This work presents an effective synthetic strategy for low-temperature and highly reversible hydrogen cycling with LiBH4 nanocomposite, showing superior hydrogen sorption capabilities and stable cyclability. The key factor influencing hydrogen cycling is the reactivity of boron, which has been successfully addressed in this study. The synergistic effects of nanostructuring and nanocatalysis contribute to efficient formation of BH4- hydrogenation and elemental boron during dehydrogenation process, shedding light on new strategies for practical hydrogen storage applications in borohydride family.

Summary: This study focuses on the catalytic effect of TiF3 on the hydrogen storage properties of the MgH2-Na3AlH6-LiBH4 system produced by ball milling. The addition of TiF3 catalyst results in a faster hydrogen uptake and release rate compared to the catalyst-free system. The apparent activation energy for the dissociation of Li3AlH6, MgH2, and NaBH4 in the TiF3-doped composite is significantly reduced. TiF3's catalytic performance is attributed to the in-situ production of Al-Ti and Al-F phases during the dehydrogenation process.

Summary: This study proposes a cost-effective method to regenerate LiBH4 by ball milling hydrous lithium metaborate with low-cost Mg-based alloys. The introduction of light rare-earth metals into Mg improves the regeneration kinetics of LiBH4 by facilitating the breakage of B-O and conversion of H+ into H-. A yield of 40% can be achieved for LiBO2 center dot 2H(2)O-CeMg12 system with a relatively short ball milling duration of 10 hours. The optimized regeneration of LiBH4 is believed to be efficient and economical, utilizing an intrinsic hydrogen source in LiBO2 center dot 2H(2)O and cheap reducing agents. This finding is expected to promote the widespread use of LiBH4 for hydrogen storage.

Summary: In this study, the effects of single non-metal doping, strain, and terminal types on the HER and OER activities of V2CO2 MXene are investigated using density functional theory (DFT). P-doped V2CO2 exhibits the best HER performance at a hydrogen coverage of q = 1/8, while N-doped V2CO2 shows the best OER performance among the studied systems. There is a strong correlation between DGH and strain, as well as DGH and valence charges of the doped atoms after applying strain to the doping structures. Additionally, mixed terminal groups enhance the performances of HER and OER, with the mixed terminal (O* and *OH) showing the highest enhancement.

Summary: Low-cost and high-performance electrocatalysts, particularly metal (oxy)hydroxides, have gained significant attention for their promising oxygen evolution reaction (OER) activity. Amorphous electrocatalysts exhibit superior activity and structural flexibility compared to crystalline counterparts, but traditional preparation techniques pose a barrier. In this study, amorphous NiFe (oxy)hydroxides on nickel foam with a large surface area and small charge transfer resistance were fabricated using an electrodeposition technique. The as-fabricated NiFe (oxy)hydroxides (Ni:Fe = 1:3) demonstrated remarkable electrocatalytic activity and stability for OER, outperforming noble metal electrocatalysts (RuO2) and most NiFe-based electrocatalysts with a low overpotential of 245 mV at a current density of 100 mA cm(-2) and a small Tafel slope of 76.9 mV dec(-1). This work provides a facile and effective method for synthesizing metal (oxy)hydroxide catalysts for high-efficiency water splitting.

Summary: Developing high-activity and capital-saving electrocatalysts for the slow kinetics of the oxygen evolution reaction (OER) is important to improve the efficiency of water splitting. In this study, metallic Ni-decorated amorphous nickel cobalt oxide (NiCoOx) nanoarray electro-catalysts were prepared using a facile reduction approach, with three-dimensional nickel foam (Ni/NiCoOx/NF) as the substrate. The Ni/NiCoOx/NF demonstrated a current density of 50 mA cm-2 at an overpotential of 348 mV in 1.0 M KOH toward OER, comparable with that of commercial RuO2 (320 mV). Moreover, Ni/NiCoOx/NF was further used as an anodic material for an overall water splitting system, achieving a current density of 10 mA cm-2 at a low voltage of 1.589 V and displaying reliable durability over at least 50 h (around 30 mA cm-2). This research provides an efficient way for generating catalysts with multi components via reduction of polymetallic oxides for electrocatalytic conversion of small molecules.

Summary: Building liquid channels in magnesium hydride by introducing lithium borohydride ion conductors improves its low-temperature hydrogen sorption. For example, 5 wt% LiBH4-doped MgH2 can release about 7.1 wt.% H-2 within 40 min at 300 degrees C, while pure MgH2 only desorbs less than 0.7 wt.% H-2. Additionally, the LiBH4-doped MgH2 exhibits faster desorption kinetics with more than 10 times enhancement compared to pure MgH2, and maintains a stable cyclic performance even after six absorption and desorption cycles. This approach provides insights for promoting hydrogen absorption and desorption of other metal hydrides.

Summary: Severe plastic deformation (SPD) processes are effective methods to refine grains, introduce crystal defects, and improve mechanical properties and functionality. High-pressure torsion (HPT) is particularly useful for preparing hydrogen storage materials, as it can process powders and induce greater plastic deformation. HPT technology not only allows for the preparation of bulk samples and enhances various properties of hydrogen storage materials, but also enables the synthesis of new alloys, intermetallics, composites, and even immiscible Mg-based alloys.
