Front cover image: Rechargeable aqueous zinc-ion batteries (ZIBs) are reputed as the promising alternatives for grid-scale energy storage. However, zinc dendrites and side reactions of zinc anode severely challenged the practical application of ZIBs. In the article number cey2.343, Huang and co-workers reported a unique surface engineering strategy by growing vertically stacked graphdiyne nanowalls (VSGDY) ion-oriented channel on zinc metal. Benefiting from the unique structure and abundant interactive sites, the VSGDY ion-oriented channel can trap/free zinc ions reversibly, inducing a segmented zinc deposition, forming a grid zinc interface, suppressing the formation of Zn dendrites.

Unraveling the Origin of Superior Activity of FeOCl for Photocatalytic Fenton Reaction

The Journal of Physical Chemistry C (2024)

Ying Liu Haifeng Wang

The photoaccelerated Fenton reaction on semiconductors has gained increasing attention for wastewater treatment, with FeOCl showing superior OH• radical generation. However, the atomic-level mechanism behind this enhanced activity remains unclear. In this study, we performed first-principles calculations to compare the photo-Fenton reaction on FeOCl(100) under photocatalytic and thermocatalytic conditions. Our results identify the [Fe2+–Fe3+] unit as the key active site driving the reaction. Fe2+ promotes the cleavage of the O–O bond in H2O2 to generate the OH• radical, while Fe3+ aids in the desorption of OH•. Under photocatalytic conditions, the enhanced activity results from rapid Fe2+/Fe3+ cycling driven by a photogenerated electron. In contrast, thermocatalysis relies on additional H2O2 to reduce Fe3+ to Fe2+. Although the photogenerated holes can also contribute by trapping OH– to form OH• radical, their effect is relatively secondary due to the lower hole-trapping capacity of the FeOCl(100) surface compared to electron trapping. A comparison with the Fe2O3(012) catalyst reveals that while both promote O–O bond under photoirradiation, Fe2O3(012) suffers from stronger OH binding due to its higher electron donation capacity. In addition, the V-shaped surface structure of Fe2O3(012) promotes bidentate adsorption, intensifying the excessive adsorption of intermediates and limiting OH• desorption. In contrast, FeOCl's moderate OH adsorption contributes to its superior catalytic efficiency. This study provides atomic-level insights into the photo-Fenton mechanism, highlighting the role of light, and offers guidance for designing more effective Fenton catalysts by comparing FeOCl with Fe2O3.

Highly thermal conductive benzoxazine‐epoxy interpenetrating polymer networks containing liquid crystalline structures Part B Polymer physics

Journal of Polymer Science (2017)

Ying Liu Jiming Chen Yaoheng Zhang Sheng Gao Zaijun Lu

A diamine‐based benzoxazine monomer (Bz) and a liquid crystalline epoxy monomer (LCE) are synthesized, respectively. Subsequently, a benzoxazine‐epoxy interpenetrating polymer network (PBEI) containing liquid crystalline structures is obtained by sequential curing of the LCE and the Bz in the presence of imidazole. The results show that the preferential curing of LCE plays a key role in the formation mechanism of liquid crystalline phase. Due to the introduction of liquid crystalline structures, the thermal conductivity of PBEI increases with increasing content of LCE. When the content of LCE is 80 wt %, the thermal conductivity reaches 0.32 W m⁻¹ K⁻¹. Additionally, the heat‐resistance of PBEI is superior to liquid crystalline epoxy resin. Among them, PBEI55 containing equal weight of Bz and LCE has better comprehensive performance. Its thermal conductivity, glass transition temperature, and the 5 % weight loss temperature are 0.28 W m⁻¹ K⁻¹, 160 °C, and 339 °C, respectively. By introducing boron nitride (BN) fillers into PBEI55, a composite of PBEI/BN with the highest thermal conductivity of 3.00 W m⁻¹ K⁻¹ is obtained. © 2017 Wiley Periodicals, Inc. J. Polym.

Electrochemical Lithium Storage Performance of Molten Salt Derived V2SnC MAX Phase

Nano-Micro Letters (2021)

Youbing Li Guoliang Ma Hui Shao Xiao Peng Jun Lu

MAX phases are gaining attention as precursors of two-dimensional MXenes that are intensively pursued in applications for electrochemical energy storage. Here, we report the preparation of V2SnC MAX phase by the molten salt method. V2SnC is investigated as a lithium storage anode, showing a high gravimetric capacity of 490 mAh g-1 and volumetric capacity of 570 mAh cm-3 as well as superior rate performance of 95 mAh g-1 (110 mAh cm-3) at 50 C, surpassing the ever-reported performance of MAX phase anodes. Supported by operando X-ray diffraction and density functional theory, a charge storage mechanism with dual redox reaction is proposed with a Sn-Li (de)alloying reaction that occurs at the edge sites of V2SnC particles where Sn atoms are exposed to the electrolyte followed by a redox reaction that occurs at V2C layers with Li. This study offers promise of using MAX phases with M-site and A-site elements that are redox active as high-rate lithium storage materials.
