Summary: In recent years, porous carbon materials have been developed for supercapacitor applications. Carbon aerogels with three-dimensional porous networks are promising for electrochemical energy storage. Physical activation using gaseous carbon dioxide provides controllable and eco-friendly processes, while chemical activation produces wastes. The activated carbon aerogels achieved a high specific surface area and large total pore volumes, leading to a high electrical double-layer capacitance. The specific gravimetric capacitance reached up to 89.1 F g(-1) with a high capacitance retention of 93.2% after 3000 cycles.

Summary: In this research, three dimensional nickel/copper cobaltite nanocomposites were successfully synthesized on stainless steel by combining electrode-position and sol-gel methods. The crystallographic configuration, chemical structure, and surface morphology of the materials were characterized by different spectroscopy and microscopy techniques. The nanocomposites exhibited high rate capability and cycling stability, attributed to the unique porous structure of the nickel core and the high electronic conductivity of the copper cobaltite shell. Moreover, the nanocomposites showed enhanced catalytic activity for methanol oxidation reaction compared to the individual copper cobaltite.

Summary: Electrolytic water splitting is a feasible and promising technique for hydrogen energy production, but the slow kinetic rate of hydrogen/oxygen evolution reactions leads to high overpotential and low energy efficiency. Pt/Ir-based nanocatalysts have become the state-of-the-art catalysts, but their high cost and low earth abundance limit their applications. Ru-based nanomaterials, particularly Ru-doped functional porous materials, have attracted attention for their low price, Pt-like hydrogen bond strength, and high EWS activity. This review summarizes the design and preparation strategies of Ru-doped functional porous materials for EWS, as well as the structure-activity relationships induced by the tuned geometric/electronic structures. The challenges and perspectives of Ru-doped functional porous materials catalysts are also proposed.

Summary: We report a bimetallic sulfide aerogel with hier-archical porosity for efficient Oxygen Evolution Reaction (OER) and pseudocapacitive charge storage. The aerogel facilitates fast charge and mass transportation, while sulfurization and secondary metal incorporation increase moderately binding active sites. The electrode exhibits excellent performance in terms of overpotential and capacitance, with increased capacity retention. XPS and NH3-TPD analysis reveal the importance of M delta+/M2/3+ ratio for OER performance and cyclability of pseudocapacitive charge storage.

Summary: Various non-hydrolytic sol-gel synthesis methods were investigated to selectively produce mesoporous t-ZrO2 or m-ZrO2 with significant specific surface areas. The presence of significant amounts of water favored the formation of m-ZrO2, while strictly non-hydrolytic routes favored the formation of t-ZrO2. The role of water in the structure of zirconia was found to be crucial.

Summary: Porous Si3N4/silica aerogel composites were prepared by sol impregnation, and their microstructure evolution and properties at high temperature were studied. The porous Si3N4 effectively inhibited the pore collapse of the aerogel and improved its temperature resistance. As the temperature increased, the specific surface area of the composite decreased while the pore size and thermal conductivity increased. The composite exhibited low thermal conductivity at 1300 degrees C, making it suitable for thermal insulation use in high-temperature environments.

Summary: This study reports the synthesis of CuxSny alloy aerogels as electrochemical CO2 reduction catalysts. The aerogels with tunable Sn contents were successfully obtained through in situ reduction and subsequent freeze-drying process. The introduced Sn inhibited the H-2 evolution reaction activity and accelerated CO desorption on the catalyst surface. The porous structure of the aerogel favored the exposure of more active sites. With the optimized composition of Cu95Sn5 aerogel, high selectivity of CO with a faradaic efficiency of over 90% was achieved in a wide potential range (-0.7 V to -1.0 V vs. RHE).

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.
