Summary: Structural optimization and electrocatalyst utilization are identified as two major factors affecting the overall performance of a lithium-air battery. In this study, a cobalt@porous carbon composite was obtained through facile annealing of a bimetallic metal-organic framework. The lithium-air battery with the assembled composite air cathode exhibited high specific capacity and cycling stability due to the catalytic activity of uniformly disseminated cobalt nanoparticles and the optimized pore-distribution characteristics. The study sheds fresh light on the design of air cathodes for lithium-air batteries.

Summary: Constructing heterointerfaces of transition metal sulfides is an effective strategy for enhancing the catalytic activity of oxygen evolution reaction (OER) by modulating their electronic structures. Incorporating these sulfides with a carbon-based support can improve their catalytic stability. In this work, FeS and Ni3S2 were encapsulated in N-doped carbon to form FeS/Ni3S2-x/NC heterostructure, and its catalytic activity was optimized by adjusting the ratio of Fe and Ni precursors. The optimized FeS/Ni3S2-2/NC heterostructure exhibited a high OER catalytic activity.

Summary: Aqueous acidic batteries are a good choice for renewable energy storage due to their safety, cost-effectiveness, environmental-friendliness, and high power capacity. However, the low voltage and energy density caused by inadequate metal anode materials hinder their practical adoption. In this study, an interfacial regulated Sn metal anode is proposed as a solution to this problem, demonstrating the potential for uniform deposition and alloying to suppress the critical issue of Sn metal shedding. The reversible Sn anode exhibits a high capacity of 442 mAh g-1 and is compatible with different cathodes, enabling the assembly of acidic batteries with sufficient output voltage, energy density, kinetics, and stability.

Summary: Natural gas hydrates have attracted attention as a potential alternative energy source, but there is no consensus on their formation mechanism. This paper proposes a method for promoting the rapid formation of gas hydrates by rupturing methane nanobubbles, creating high temperature and pressure conditions for methane-water mixing. Molecular dynamics simulations confirm the formation of gas hydrates through this method. The rupture of methane nanobubbles induced by shock waves leads to increased molecular motion, resulting in extreme local temperature and pressure, facilitating rapid hydrate formation.
