The imbalance of charge injection is considered to be a major factor that limits the device performance of cadmium‐free quantum‐dot light‐emitting diodes (QLEDs). In this work, high‐performance cadmium‐free Cu─In─Zn─S(CIZS)‐based QLEDs are designed and fabricated through tailoring interfacial energy level alignment and improving the balance of charge injection. This is achieved by introducing a bilayered...
Zn‐based electrochemical energy storage (EES) systems are attracting more attention, whereas their large‐scale application is restricted by the dendrite and parasitic reaction‐caused unstable Zn anodes. Herein, a negatively charged hydrophobic carbon nano‐onion (CNO) interfacial layer is proposed to realize ultrastable and high‐rate Zn anodes, enabling high‐performance Zn‐based EES. For the CNO interfacial...
The slow charge transfer and high energy barrier are the key restrictions of cost‐effective electrocatalysts for hydrogen production. A hierarchical heterostructure of MoN@NiFe‐layered double hydroxides (LDH) is developed, with NiFe‐LDH nanosheets supported on MoN nanowire arrays. The as‐prepared MoN@NiFe‐LDH exhibits a remarkably high performance on hydrogen production in alkaline medium, which is...
Zinc anode‐based aqueous batteries have attracted considerable interest for large‐scale energy storage and wearable devices. Unfortunately, the formation of Zn dendrite, parasitic hydrogen evolution reaction (HER), and irreversible by‐products, seriously restrict their practical applications. Herein, a series of compact and uniform metal‐organic frameworks (MOFs) films with precisely controlled thickness...
CaZnOS‐based semiconductors are the only series of material system discovered that can simultaneously realize a large number of dopant elements to directly fulfill the highly efficient full‐spectrum functionality from ultraviolet to near‐infrared under the same force/pressure. Nevertheless, owing to the high agglomeration of the high temperature solid phase manufacturing process, which is unable to...
Hierarchically porous carbon nanomaterials with well‐defined architecture can afford a promising platform for effectively addressing energy and environmental concerns. Herein, a totally green and straightforward synthesis strategy for the fabrication of hierarchically porous carbon nanotubes (HPCNTs) by a simple carbonization treatment without any assistance of soft/hard templates and activation procedures...
Corannulene, a kind of bowl like polycyclic aromatic hydrocarbon (PAH), whose molecule is composed of a central pentagon and five closely adjacent hexagons on the pentagon's five sides, has received great scientific interest among research groups. In this review, the syntheses, characteristic molecule structure and properties of corannulene are clarified, as well as its derivatives with different...
