The growing concern about scarcity and large-scale applications of lithium resources has attracted efforts to realize cost-effective phosphate-based cathode materials for next-generation Na-ion batteries(NIBs).In previous work,a series of materials(such as Na_(4)Fe_(3)(PO_(4))_(2)(P_(2)O_(7)),Na_(3)VCr(PO_(4))_(3),Na_(4)VMn(PO_(4))3,Na_(3)MnTi(PO_(4))_(3),Na_(3)MnZr(PO_(4))3,etc)with∼120 mAh g^(-1) specific capacity and high operating potential has been ***,the mass ratio of the total transition metal in the above compounds is only∼22 wt%,which means that one-electron transfer for each transition metal shows a limited capacity(the mass ratio of Fe is 35.4 wt%in LiFePO_(4)).Therefore,a multi-electron transfer reaction is necessary to catch up to or go beyond the electrochemical performance of LiFePO_(4).This review summarizes the reported NASICON-type and other phosphate-based cathode *** the basis of the aforementioned experimental results,we pinpoint the multi-electron behavior of transition metals and shed light on designing rules for developing high-capacity cathodes in NIBs.

CoS_(2) is considered to be a promising electrocatalyst for hydrogen evolution reaction(HER).However,its further widespread applications are hampered by the unsatisfactory activity due to relatively high chemisorption energy for hydrogen ***,theoretical predictions of first-principles calculations reveal that the introduction of a Cl-terminated MXenes-Ti_(3)CNCl_(2) can significantly reduce the HER potential of CoS_(2)-based materials and the Ti_(3)CNCl_(2)@CoS_(2) core–shell nanostructure has Gibbs free energy of hydrogen adsorption(|ΔGH|)close to zero,much lower than that of the pristine CoS_(2) and Ti_(3)CNCl_(2).Inspired by the theoretical predictions,we have successfully fabricated a unique Ti_(3)CNCl_(2)@CoS_(2) core–shell nanostructure by ingeniously coupling CoS_(2) with a Cl-terminated MXenes-Ti_(3)CNCl_(2).Interface-charge transfer between CoS_(2) and Ti_(3)CNCl_(2) results in a higher degree of electronic localization and a formation of chemical ***,the Ti_(3)CNCl_(2)@CoS_(2) core–shell nanostructure achieves a significant enhancement in HER activity compared to pristine CoS_(2) and Ti_(3)CNCl_(2).Theoretical calculations further confirm that the partial density of states of CoS_(2) after hybridization becomes more non-localized,and easier to interact with hydrogen ions,thus boosting HER *** this work,the success of oriented experimental fabrication of high-efficiency Ti_(3)CNCl_(2)@CoS_(2) electrocatalysts guided by theoretical predictions provides a powerful lead for the further strategic design and fabrication of efficient HER electrocatalysts.

Trioxane (Tox) is an important source of anhydrous formaldehyde, which is used in large quantities in industrial production resulting in large quantities of low concentration Tox wastewater. Liquid-liquid extraction is one of the commonly used methods for wastewater resource recycling. This study presents a method on the separation of Tox from wastewater using hydrophobic deep eutectic solvents (HDES). Firstly, Thy-BA and Thy-DA were screened from 12 HDES by extraction performance and solubility in water. The effects of different molar ratios of HDES, extraction temperature and addition of acetic acid as impurity on the extraction performance were further investigated. For the measured ternary phase data of HDES-Tox-water, the reliability of the data was verified using the Othmer-Tobias and Hand equations, and the data were fitted using the NRTL model. Quantum chemistry was used to calculate the interaction energy of HDES with Tox and to establish a correlation with the extraction efficiency. Hydrogen bonding was found to be the main force for separating Tox by electrostatic potential and interaction region indicator analysis. Molecular dynamics computing found that Thy was a substance that plays a major role in Thy-BA and Thy-DA. Ultimately, it was discovered that the chosen HDES has great recycling and thermal stability characteristics. This work explores three aspects of phase equilibrium, thermodynamics and microscopic separation mechanism revelation to support the systematic recovery of Tox wastewater. © 2025 Elsevier B.V.
