Confined 1T‐VSe2 Ferromagnetic Nanoparticles
In article number 2300122, Cailei Yuan, Shouguo Wang, and co‐workers report confined 1T‐VSe2 ferromagnetic nanoparticles in amorphous carbon matrix for external magnetic fields assisted highly efficient oxygen evolution reaction (OER). Benefiting from the confined structure and the high‐efficient spin‐related OER kinetics under external magnetic fields,...
As a clean and effective approach, the introduction of external magnetic fields to improve the performance of catalysts has attracted extensive attention. Owing to its room‐temperature ferromagnetism, chemical stability, and earth abundance, VSe2 is expected to be a promising and cost‐effective ferromagnetic electrocatalyst for the accomplishment of high‐efficient spin‐related OER kinetics. In this...
2D materials with low symmetry are explored in recent years because of their anisotropic advantage in polarization‐sensitive photodetection. Herein the controllably grown hexagonal magnetic semiconducting α‐MnTe nanoribbons are reported with a highly anisotropic (100) surface and their high sensitivity to polarization in a broadband photodetection, whereas the hexagonal structure is highly symmetric...
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...
A cellulose paper is used impregnated with light‐emitting CdTe nanocrystals and carbon dots, and filled with a polyurethane to fabricate uniform transparent composite films with bright photoluminescence of red (R), green (G), and blue (B) (RGB) colors. A building brick‐like assembly method is introduced to realize RGB multicolor emission patterns from this composite material. By sectioning out individual...
In the information age, it is important to protect the security and integrity of the information. As a result, the fluorescent ink as an antifake technology and the fingermark as an information carrier have aroused great interest. In this work, highly water‐soluble lanthanide (Ln3+)‐doped tetragonal phase (t‐) LaVO4 nanoparticles (NPs) are successfully obtained via a simple, fast, and green microwave‐assisted...
