Summary: Moderate adsorption of oxygenated intermediates plays a crucial role in the rational design of high-efficiency oxygen reduction reaction (ORR) electrocatalysts. Defect engineering, which can adjust the coordination environment of catalytic active sites, is a reliable strategy for tuning the geometric structure of nanomaterials. However, it remains challenging to uniformly disperse high-coordinated defects into ultrathin 2D nanosheets due to the limitations of controllable nanocrystal fabrication. This study introduces atomic-scale cavities (ASCs) as a new type of high-coordinated active site and successfully incorporates them into suprathin Pd (111)-exposed metallene for enhanced ORR performance.

Summary: In this article, the great potential of two-dimensional transition metal dichalcogenides (TMDs) as cost-effective catalysts in hydrogen evolution reaction is demonstrated. Various defect engineering strategies, including intrinsic defects (vacancy and edges) and extrinsic defects (metal doping, nonmetal doping, and hybrid doping), are systematically summarized. The electronic structure, intermediate adsorption/desorption energies, and possible catalytic mechanisms are discussed based on theoretical simulations and experimental results. The intrinsic relationship between different defect types and electrocatalytic properties is emphasized. Furthermore, current opportunities and challenges for mechanical investigations and applications of defective TMD-based catalysts are presented to provide valuable insights for fabricating high-efficiency TMD-based electrocatalysts.

Summary: Binary metal chalcogenides (BMCs) exhibit superior electrochemical performance compared to mono metal counterparts due to their abundant phase interfaces, active sites, kinetics, and electronic conductivity. However, challenges such as poor ionic conductivities, volume expansions, and structural issues still need to be addressed through engineering BMC nanostructures for optimized electrode materials. Understanding the electrochemical response of BMCs remains a barrier to their widespread application, but this review aims to provide insights into tackling these issues for better electrochemical devices.

Summary: Water electrolysis for hydrogen production is considered the future of green energy, but current electrolyzer technologies relying on ultrapure fresh water cannot meet the increasing hydrogen demands. Seawater, as an abundant feedstock, has emerged as a potential solution, but its complex composition and chlorine chemistry make the process complicated. Recently developed catalysts offer hope for direct seawater splitting, but further optimization is needed for commercial use.

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.
