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
