Summary: This research presents a method of hydrogen production from formic acid using fluidized bed technology. A core-shell catalyst was developed by applying a Ni layer on cenospheres via gaseous deposition. The efficiency of formic acid decomposition was tested continuously in the range of 200-500°C. An analytical method based on infrared spectroscopy was developed for the continuous monitoring of product concentration in the gas phase. The proposed solution in a fluidized bed was compared with other methods, showing advantages such as on-demand hydrogen generation, use of biomass or CO2 as an energy carrier, process simplicity, easy temperature control, repeatability, scalability, continuous monitoring, and high hydrogen generation efficiency per unit volume.

Summary: Efficient catalysts for formic acid decomposition have been extensively studied. In this study, the Au3Pd1 intermetallic compound is designed as a single atom catalyst for formic acid dehydrogenation. The thermodynamic stability, electronic structure, and reaction mechanism of the Au3Pd1 catalyst are systematically investigated, and it is found that surface charge polarization and atom-ordered arrangement play an important role in the efficient dehydrogenation process. The results suggest that this intermetallic-based catalyst can be applied to other systems and provide general guidance for designing efficient catalysts.

Summary: In this study, composite catalysts of MoS2 and MoO2 were prepared using a one-step hydrothermal method and used for photocatalytic hydrogen production. The 2H-MoS2/MoO2 composite catalyst showed the best performance with 48% MoO2 content, achieving a hydrogen yield of 960 mu mol/h and an improved selectivity by 22%. The excellent performance of the composite catalyst was attributed to the formation of a heterogeneous structure between MoS2 and MoO2, improving the migration of photogenerated carriers and reducing the possibilities of recombination.

Summary: The study investigated the reaction chemistry of silanes and hydrogen at para-terphenyl diphosphine-supported molybdenum complexes in the context of carbon dioxide reduction. While CO2 hydrosilylation commonly yields reduction products via silyl acetals, C-O cleavage of CO2 and hydrogenation occur independently of silanes in the system.

Summary: To achieve stable cycling of high-energy-density and high-voltage anode-free lithium metal batteries, the interfacial stability of both lithium metal anode and high-voltage cathode is demanded. By using an ether-based local high-concentration electrolyte and a minute amount of lithium difluoro(oxalate)borate (LiDFOB) additive, efficient lithium metal plating-stripping and increased oxidation stability are achieved, leading to high-capacity retention and mitigated transition metals dissolution.

Summary: In this study, three series of alloys were prepared and their crystal structural characteristics and hydrogen storage properties were investigated. The results showed that a single C14-Laves phase with homogeneous element distribution existed in all alloys. The hydrogen absorption/desorption plateau of the alloys increased as the Fe, Mn, or Ti content increased. The hydrogen storage capacity of the alloys also correlated negatively with the hydrogen affinity of interstitial sites. Ti0.935Zr0.085Cr1.3Mn0.3Fe0.4 alloy exhibited saturated hydrogenation under 8 MPa at 293 K and dehydrogenation around 24.91 MPa pressure at 363 K with a hydrogen capacity of 1.74 wt%, as well as excellent cycling performance and mere hysteresis. Ti0.92Zr0.10Cr1.0Mn0.6Fe0.4 alloy showed promising hydrogen capacity of 1.86 wt% at 283 K and a dehydrogenation pressure of 27.94 MPa at 363 K, along with satisfactory cycling durability. This study can guide the compositional design of AB2-type hydrogen storage alloys for hydrogen compression application.

Summary: Due to the environmental pollution and thermal risks of lithium-ion batteries, it is necessary to recycle and assess the safety of spent lithium-ion batteries. In this study, lithium tin alloys (LixSny) were prepared via mechanical alloying to simulate the tin anode materials at different lithium-embedded states. The Li22Sn5 alloy exhibited the best hydrolysis performance, releasing 351 mL g-1 of hydrogen in 10 seconds at 293 K. Safety evaluation was conducted based on hydrolysis performance, maximum adiabatic temperature rise, and other parameters. The study also demonstrated the controllable reaction rates by tailoring the solution components, enhancing the security and controllability for practical application. Furthermore, the hydrogen production of Li22Sn5 sample increased to 624 mL g-1, even at a subzero temperature of 243 K, generating 510 mL g-1 of hydrogen within 30 seconds. This research provides a novel approach for the safety evaluation and recycling of tin anode materials in spent lithium-ion batteries.

Summary: In this study, the poisoning resistance behaviors and mechanism of ZrCo in H2+CO2 mixed gas were systematically investigated. Even trace amounts of CO2 can strongly deteriorate hydrogenation kinetics of ZrCo, but this phenomenon can be mitigated by further increasing the inputting pressure of the mixed gas. In-situ surface reconstruction strategy by high-temperature treatment was proposed, which enhanced the CO2 poisoning tolerance of ZrCo through the formation of metallic Co nanoclusters on ZrCo surface.

Summary: Metal borohydrides have high theoretical hydrogen production/storage densities and offer efficient real-time hydrogen supply for electronics. However, their practical applications are limited. Strategies to overcome these limitations, such as optimizing the boron/hydrogen source and reducing agent, are summarized in this review. Ouyang developed a practical and low-cost method for regenerating MBH4 by ball milling, which has the potential to decrease the synthesis cost and increase the reversibility of metal borohydrides.
