Owing to the interacted anion and cation redox dynamics in Li2MnO3, the high energy density can be obtained for lithium‐rich manganese‐based layered transition metal (TM) oxide [Li1.2Ni0.2Mn0.6O2, LNMO]. However, irreversible migration of Mn ions and oxygen release during highly de‐lithiation can destroy its layered structure, leading to voltage and capacity decline. Herein, non‐TM antimony (Sb) is...
Developing high‐efficiency electrocatalysts toward overall water splitting is an increasingly important area for sustainable energy evolution. Theoretical calculation results demonstrate that the incorporation of Ru optimizes the Gibbs free energy of adsorption of H2O molecules and intermediates for the hydrogen/oxygen evolution reactions (HER/OER) on metal selenide sites, thus boosting electrocatalytic...
The development of efficient and stable noble‐metal‐free electrocatalysts for hydrogen evolution reaction (HER) in alkaline media is still a challenge. Herein, a hybrid material formed by the interconnection of Ni17W3 intermetallic compound with metallic W is demonstrated for HER. The Ni17W3–W hybrid is prepared by the atmosphere‐ and thermal‐induced phase‐separation strategy from a single‐phase precursor...
Poly(ε‐caprolactone) (PCL)‐based nanomaterials, such as nanoparticles and liposomes, have exhibited great potential as controlled release systems, but the difficulties in large‐scale fabrication limit their practical applications. Among the various methods being developed to fabricate polymer nanosheets (PNSs) for different applications, such as Langmuir–Blodgett technique and layer‐by‐layer assembly,...
All‐inorganic photodetectors based on scattered CsPbBr3 nanoplatelets with lateral dimension as large as 10 µm are fabricated, and the CsPbBr3 nanoplatelets are solution processed governed by a newly developed ion‐exchange soldering mechanism. Under illumination of a 442 nm laser, the photoresponsivity of photodetectors based on these scattered CsPbBr3 nanoplatelets is as high as 34 A W−1, which is...
The recent success of organometallic halide perovskites (OHPs) in photovoltaic devices has triggered lots of corresponding research and many perovskite analogues have been developed to look for devices with comparable performance but better stability. Upon the preparation of all inorganic halide perovskite nanocrystals (IHP NCs), research activities have soared due to their better stability, ultrahigh...
