Summary: The presence of surface oxygen groups in graphene nanoplatelets enhances the charge storage capacity in bromide redox electrolytes, while the pore size of carbons affects the rate performance of devices. The charge storage performance of supercapatteries with graphene nanoplatelets can be attributed to the porous structure affecting the dynamics of non-active cations and the possible interaction with redox species. It is important to consider the correlation between surface groups, microstructure of electrode materials, and redox electrolytes for commercializing these devices.

Summary: Due to the narrow electrochemical stability window (ESW), electric double-layer supercapacitors with aqueous electrolytes have low energy density, limiting their application. However, the addition of erythritol (Et) can decrease water molecules and break the hydrogen bond network, expanding the ESW. By utilizing 37.9% Et additive in 1 M LiTFSI electrolyte, the symmetric supercapacitor achieves an expanded ESW from 1.8 to 2.1 V, increased energy density of 13.3 Wh kg(-1), high specific capacitance of 86.6F g(-1), and capacitance retention rate of 73.8% after 10,000 cycles. This study provides an efficient strategy for high energy density aqueous supercapacitors.

This study developed a heterostructured Ni3Se2 @NiCo-LDH system where NiCo-LDH nanosheets were electrodeposited on hydrothermally grown pine tree-like Ni3Se2 structures. The heterostructured electrode exhibited significantly enhanced oxygen evolution capability due to the high conductivity of Ni3Se2 and the intrinsic OER activity of NiCo-LDH, as well as the generation of additional active sites at the heterointerface. The findings of this study are expected to pave the way for the production of further heterostructure electrocatalysts.

Summary: In this study, a porous NiFeP/MoO2@Co3O4 core-shell heterostructure was constructed on a nickel foam using a hydrothermal route, phosphorization treatment and atomic layer deposition. The resulting NiFeP/MoO2@Co3O4 cuboids exhibited lower charge transfer resistance, rich electroactive sites, and shorter ion diffusion paths. The excellent supercapacitive performance of the cuboids was attributed to the rich active sites and strong electronic interaction between Co and Ni/Fe/Mo species. Furthermore, a hybrid device with a NiFeP/MoO2@Co3O4 cathode and a graphene anode achieved a high energy density and exceptional capacity retention.

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.
