The poor reversibility and stability of Zn metal anode (ZMA) caused by uncontrolled Zn deposition behaviors and serious side reactions severely impeded the practical application of aqueous Zn metal battery. Herein, a liquid‐dynamic and self‐adaptive protective layer (LSPL) was constructed on the ZMA surface for inhibiting dendrites and by‐products formation. Interestingly, the outer LSPL consists...
Sluggish oxygen evolution reactions on photoanode surfaces severely limit the application of photoelectrochemical (PEC) water splitting. The loading of cocatalysts on photoanodes has been recognized as the simplest and most efficient optimization scheme, which can reduce the surface barrier, provide more active sites, and accelerate the surface catalytic reaction kinetics. Nevertheless, the introduction...
The dendrite growth and parasitic reactions that occur on Zn metal anode (ZMA)/electrolyte interface hinder the development of aqueous zinc ion batteries (AZIBs) in next‐generation renewable energy storage systems.

Owing to outstanding optoelectronic properties, lead halide perovskite nanocrystals (PNCs) are considered promising emitters for next‐generation displays. However, the development of pure blue (460‐470 nm) perovskite nanocrystal light‐emitting diodes (PNC‐LEDs), which correspond to the requirements of Rec. 2020 standard, lag far behind that of their green and red counterparts. Here, pure blue CsPb(Br/Cl)...

In this work, by employing...
Conjugated polymer polypyrrole (PPy) with high electrical conductivity and excellent photothermal effect has been adopted as multifunctional surface modifier on ternary metal sulfide (CdIn2S4, CIS) photoanode for photoelectrochemical (PEC) water splitting for the first time. As a p‐type conducting polymer, PPy forms p–n junction with n‐type CIS to relieve the bulk carrier recombination. Besides, the...
Zinc metal is an ideal candidate for aqueous rechargeable batteries due to its high theoretical capacity and natural abundance.
