Summary: Generating hydrogen fuel through electrochemical water splitting powered by sustainable energy sources is a promising approach for future renewable energy. However, current electrolysis methods require desalinated water, leading to energy costs and water scarcity. This study introduces a cost-effective electrocatalyst, the surface reconstructed nickel-iron layered double hydroxide (NF-LDH), which can split saline water without chloride corrosion. The NF-LDH electrode exhibits exceptional activity and durability, with Ni3Fe alloy phase responsible for catalytic activity and corrosion resistance.

Summary: Ni-Co LDHs were synthesized with different Ni/Co molar ratios and used as cathode materials for Ni-MH batteries. Compared with Ni(OH)2, Ni-Co LDHs electrodes exhibited higher discharge capacity and cycling stability. The NC 2 electrode with a Ni/Co molar ratio of 4:1 showed the highest discharge capacity and capacity retention after 200 cycles. The unique morphology and enlarged interlayer spacing of Ni-Co LDHs promoted ion transmission and charge transfer, while their structural stability and synergies with Co-Co LDHs were important for electrochemical performances.

Summary: Layered double hydroxides (LDHs) are promising electrodes for supercapacitors due to their adjustable composition and superior high capacity, but their experimental specific capacity is lower than theoretical value. Intercalating large-sized anions to increase interlayer spacing is crucial for performance improvement, as demonstrated in a study where a cobalt-nickel LDH hollowcage intercalated with 1,4-benzenedicarboxylic acid showed improved specific capacity and rate performance. The sample with the largest layer spacing achieved a maximum specific capacity of 229 mA h g(-1) at 1 A g(-1), and a hybrid supercapacitor with this sample showed good energy density and cycle stability.

Summary: Researchers have been developing novel and advanced materials to meet the high demand for efficient and low-cost materials for energy and environmental applications. Layered double hydroxides (LDHs) have been found to be excellent materials due to their tunable elemental composition and diverse nanostructures, particularly in the fields of supercapacitors, electrocatalysts, and sensors. The electrodeposition method for preparing binder-free LDHs thin-film electrodes allows for the fabrication of uniform and well-oriented thin films with tunable elemental composition.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
