    Hierarchically Plasmonic Z‑Scheme Photocatalyst of Ag/AgCl Nanocrystals Decorated Mesoporous Single-Crystalline Metastable Bi<sub>20</sub>TiO<sub>32</sub> Nanosheets

    The hierarchical photocatalysts of Ag–AgCl@Bi<sub>20</sub>TiO<sub>32</sub> composites have been successfully synthesized by anchoring Ag–AgCl nanocrystals on the surfaces of mesoporous single-crystalline metastable Bi<sub>20</sub>TiO<sub>32</sub> nanosheets via a two-stage strategy for excellent visible-light-driven photocatalytic activities in the Z-scheme system. First, the single-crystalline metastable Bi<sub>20</sub>TiO<sub>32</sub> nanosheets with tetragonal structures were prepared via a facile hydrothermal process in assistance with the post-heat-treatment route using benzyl alcohol. Especially, the mesoporous Bi<sub>20</sub>TiO<sub>32</sub> nanosheets showed high photocatalytic activity for the degradation of rhodamine B dye under visible-light irradiation. Then, the as-prepared mesoporous Bi<sub>20</sub>TiO<sub>32</sub> nanosheets were used as a support for loading Ag–AgCl nanocrystals using the deposition–precipitation method and irradiation–reduction process to fabricate the Ag–AgCl@Bi<sub>20</sub>TiO<sub>32</sub> composites. Inspiringly, the hierarchical Ag–AgCl@Bi<sub>20</sub>TiO<sub>32</sub> photocatalyst has the higher photocatalytic performance than Ag–AgCl nanocrystals and mesoporous Bi<sub>20</sub>TiO<sub>32</sub> nanosheets over the degradation of rhodamine B and acid orange 7 dyes, which is attributed to the effective charge transfer from plasmon-excited Ag nanocrystal to Bi<sub>20</sub>TiO<sub>32</sub> for the construction of a Z-scheme visible-light photocatalyst. This work could provide new insights into the fabrication of hierarchically plasmonic photocatalysts with high performance and facilitate their practical application in environmental issues

    In Situ Self-Assembled FeWO<sub>4</sub>/Graphene Mesoporous Composites for Li-Ion and Na-Ion Batteries

    With the growing demands for large-scale applications, rechargeable batteries with cost-effective and environmental-friendly characteristics have gained much attention in recent years. However, some practical challenges still exist in getting ideal electrode materials. In this work, three-dimensional FeWO<sub>4</sub>/graphene mesoporous composites with incredibly tiny nanospheres of 5–15 nm in diameter have been synthesized by an in situ self-assembled hydrothermal route. First-principles density functional theory has been used to theoretically investigate the crystal structure change and the insertion/extraction mechanism of Li and Na ions. Unlike most graphene-coated materials, which suffer the restacking of graphene layers and experience significant irreversible capacity losses during charge and discharge process, the as-prepared composites have alleviated this issue by incorporating tiny solid nanospheres into the graphene layers to reduce the restacking degree. High capacity and excellent cyclic stability have been achieved for both Li-ion and Na-ion batteries. At the current density of 100 mA g<sup>–1</sup>, the discharge capacity for Li-ion batteries remains as high as 597 mAh g<sup>–1</sup> after 100 cycles. The Na-ion batteries also exhibit good electrochemical performance with a capacity of 377 mAh g<sup>–1</sup> at 20 mA g<sup>–1</sup> over 50 cycles. The synthetic procedure is simple, cost-effective and scalable for mass production, representing a step further toward the realization of sustainable batteries for efficient stationary energy storage
