Summary: The rational design of epitaxial heterostructures based on the growth of compatible phases with lattice similarity can enhance electrocatalytic activity. The charge transfer and reinforced electron conduction at the epitaxial heterointerface between Ru clusters and Ni3N substrate are studied through theoretical simulations, leading to optimized adsorption behaviors and reduced activation energy barriers.

Summary: Due to its higher energy density, high thermal stability, and low cost, the spinel LiNi0.5Mn1.5O4 (LNMO) has great potential as a cathode material for lithium-ion batteries. However, the interfacial and bulk reactions in LNMO can lead to capacity decay. In this study, a Ge-doping strategy is proposed to regulate the ratio of ordered/disordered phases in LNMO, resulting in exceptional structural stability and improved cycling performance. The incorporation of Ge into LNMO increases the amount of Mn4+ and blocks the diffusion of transition metal ions, preventing capacity deterioration during cycling.

Summary: The development of an electrochemical hydrogen evolution catalyst with high activity, low Pt loading, and excellent stability is crucial for the widespread promotion and practical application of hydrogen energy. In this study, we introduced ZIFs and their derivatives with tunable pore size and large specific surface area, which were carbonized at high temperatures and supported with Pt as catalysts for the hydrogen evolution reaction. The best Pt/WC catalyst, Pt/WC-3, with a Pt content of 8.3 wt % exhibited a low overpotential of 28 mV in 0.5 M H2SO4, significantly lower than the 34 mV of 20% commercial Pt/C. It also showed excellent durability with a minimal increase in overpotential after 40,000 s of continuous operation at 10 mA cm(-2).

Summary: The rapid construction of water electrolysis catalysts using a sacrificing template in an electrochemical environment is not widely studied. In this research, a highly effective alkaline catalyst is designed by using a fluorine-rich nickel fluoride (NiF2) grown on nickel foam (NF) as a sacrificial template. The NiF2 template can be transformed into nickel hydroxide (Ni(OH)(2)) and nickel oxyhydroxide (NiOOH) in the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively, through rapid ion exchange in the electrochemical environment. The catalyst exhibits low overpotentials for HER and OER, with outstanding stability and a low cell voltage for overall water splitting.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
