Summary: This study reports a method for direct hydrogenation of O(2) gas to form H2O2 using a membrane reactor without H-2 gas. Hydrogen is obtained from water source and the reactor is powered by electricity. The concentration of H(2)O(2) can be increased about 8 times by optimizing the ratio of methanol-to-water in the chemical chamber and through catalyst design. The study also demonstrates the sensitivity of H(2)O(2) concentration to its decomposition rate, which can be minimized using AuPd alloy catalysts.

Summary: In this study, a homogeneous catalyst is used to synthesize hydrogen peroxide using H2 and O2 in water, eliminating the need for flammable H2/O2 mixtures and cocatalysts. The catalyst is capable of extracting electrons from H2, storing them for the reduction of O2, and then converting the reduced oxygen to H2O2. The catalyst exhibits the highest turnover number (TON) among all homogeneous catalysts.

Summary: This paper reports a method for the synthesis of H2O2 using a homogeneous catalyst in water, using only H2 and O2 without flammable mixtures or cocatalysts. The catalyst can remove electrons from H2, store them for the reduction of O2, and allow the protonation of the reduced oxygen to form H2O2. The turnover number (TON) is 910 under an H2/O2 (95/5) atmosphere (1.9 MPa) for 12 hours at 23 degrees C, which is the highest among any homogeneous catalysts. Furthermore, a reaction mechanism based on two crystal structures is proposed.

Summary: In this study, a comparative DFT calculation was conducted to understand the elementary surface reactions of CO hydrogenation reactions on Cu and ZnCu alloy surfaces. The results revealed that the reaction pathways and rate-limiting steps were different on ZnCu alloy and Cu surfaces. The key difference lies in the desorption of CH3OH* species on ZnCu alloy surface, which produces CH3OH, while on Cu surface, it undergoes H*-assisted decomposition to CH3* and eventually to CH4. These findings provide a comprehensive understanding of CO hydrogenation reactions on Cu and ZnCu alloy surfaces.

Summary: We report a novel nanoporous CrFe alloy with ordered structure, which shows rapid strain hardening and high resistance to deformation. The regular skeletons can be entirely compacted between parallel two sides, facilitating the densification of nanoporous alloy. The presence of internal boundaries acts as barriers for dislocation motion, thus improving strain hardening.

Summary: In this study, a series of isostructural aluminum-based metal-organic frameworks (MOFs) with tunable polarities were used as supports for Pd nanoparticles. The polarity of the ligands in the MOFs was found to play a critical role in the catalytic activity and selectivity of direct hydrogen peroxide synthesis. The highest H2O2 yield was achieved with Pd@A520, which was approximately 4.9 times higher than that of commercial Pd/C. Quantitative relationships were established between the ligand polarity of MOFs and various catalytic properties.

Summary: Anode-free lithium metal batteries (AFLMBs) are considered as potential high-energy devices in the future. To overcome the challenges of interface reactions and internal short circuits, a solvent-free approach is proposed to fabricate deformable sulfide composite solid electrolyte (SCSE-4) by incorporating lithium argyrodite (LPSC) and other materials. The SCSE-4 electrolyte exhibits high Li-dendrite inhibition capability and delivers ultra-stable cycling with high coulombic efficiency.

Summary: Carbon@titania yolk-shell nanostructures are successfully synthesized and used as a photocatalyst to degrade acetaminophen. The presence of residual carbon nanospheres is found to improve the photocatalytic efficiency. X-ray absorption spectroscopy analysis reveals the structural and electronic changes in the hollow shell. In situ XAS measurements show that the existence of amorphous carbon nanospheres inhibits the recombination of electron-hole pairs, leading to enhanced photodegradation of acetaminophen. Charge transfer from TiO2 to carbon nanospheres reduces electron-hole recombination and increases photocatalytic efficiency.

Summary: Anode materials of metal oxides based on conversion reaction in lithium-ion batteries usually have a higher capacity than commercial graphite anodes, and the porous forms of the materials can effectively reduce the volume change during (de)lithiation. This study focuses on tetragonal gamma-Fe2O3 as a representative intrinsic nano-porous metal oxide anode material. The structural evolution of gamma-Fe2O3 not only contributes to the understanding of conversion reactions of vacancy-ordered metal oxides, but also provides a new method for the fabrication of twinning structures in metal oxides, including cathode materials.

Summary: Energy conversion from chemical to electrical energy through electrochemical processes using fuel cells is a promising advanced technology to address global environmental issues. However, the development of cathode materials for proton exchange membrane fuel cells (PEMFCs) still faces challenges due to their practical requirements for activity and stability. Introducing oxides into the electrocatalysts is an important way to improve performance. Therefore, hybrid metal-oxide-carbon materials with high conductivity, electronic interaction, and carbon corrosion resistance are strongly recommended as support materials for Pt nanoparticles to develop Pt-based electrocatalysts for fuel cell applications.

Summary: This study investigates the influence of fluoroethylene carbonate (FEC) and lithium difluorophosphate (LiPO2F2) dual additives on the cycling stability of lithium metal batteries using in situ diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS). The results show that the presence of these additives can suppress the formation of SEI species on the copper anode, improving the cycling stability. LiPF6 reacts with the copper anode to form LixPFy, leading to a reduction peak at approximately 1.44V in constant voltage (CV) analysis. FEC leads to the continuous formation of poly(FEC) during the first lithiation cycle, while EC and DEC are electrochemically reduced to (CH2OCO2Li)2 and Li2CO3. The redox of LiPO2F2 and the decomposition of LiPF6 are partly suppressed by the presence of FEC.

Summary: The development of next-generation rechargeable lithium-metal batteries (LMBs) is crucial for improving the performance of existing lithium-ion batteries. However, uncontrollable lithium dendrite growth and unstable solid electrolyte interphases (SEI) in lithium-metal anodes limit their practical applications. A study found that magnesium (Mg) doping on the Li anode may aid in the formation of a stable SEI layer, improving the electrochemical performance of LMBs. In this study, ab initio molecular dynamics (AIMD) simulations were used to investigate the interfacial reactions between the electrolytes and the Mg-doped Li metal anode surface. The results showed that the Mg-doped lithium anode promoted the decomposition of LiPF6 and solvents, leading to the formation of a denser SEI layer.
