Partial substitution of V by other transition metals in Na3V2(PO4)3 (NVP) can improve the electrochemical performance of NVP as a cathode for sodium–ion batteries (SIBs). Herein, phosphate Na–V–Mn–Ni–containing composites based on NASICON (Natrium Super Ionic Conductor)–type structure have been fabricated by sol–gel method. The synchrotron–based X–ray study, X–ray diffraction (XRD), and X–ray photoelectron...
The crystalline/amorphous heterophase nanostructures are promising functional materials for biomedicals, catalysis, energy conversion, and storage. Despite great progress is achieved, facile synthesis of crystalline metal/amorphous multinary metal oxides nanohybrids remains challenging, and their electrocatalytic oxygen evolution reaction (OER) performance along with the catalytic mechanism are not...
Bi2O3/rare earth oxide biphasic absorbers are attractive for high‐efficiency X‐ray shielding due to the complementary X‐ray absorption effects. However, its application is severely hindered by poor interphasic contact. Here, a new Janus interface engineering strategy is reported for the construction of continuous and flexible Bi2O3/Gd2O3 crystal nanofibrous membranes (FJNMs) with micro/nano dual self‐strengthening...
Recently, single‐atom catalysts are attracting much attention in sensor field due to their remarkable peroxidase‐ or oxidase‐like activities. Herein, peroxidase‐like FeCoZn triple‐atom catalyst supported on S‐ and N‐doped carbon derived from ZIF‐8 (FeCoZn‐TAC/SNC) serves as a proof‐of‐concept nanozyme. In this paper, a dual‐channel nanozyme‐based colorimetric sensor array is presented for identifying...
2D Ruddlesden‐Popper perovskites (PVKs) have recently shown overwhelming potential in various optoelectronic devices on account of enhanced stability to their 3D counterparts. So far, regulating the phase distribution and orientation of 2D perovskite thin films remains challenging to achieve efficient charge transport. This work elucidates the balance struck between sufficient gradient sedimentation...
Water splitting to produce hydrogen is an effective means to alleviate the energy crisis. The anodic oxygen‐evolving reaction (OER) limits the overall efficiency due to its high energy barrier. To address this, layered double hydroxides (LDHs) with high catalytic activities have been widely studied, especially those modified with CeO2, either bound to the surface or doped into interior. However, experimental...
Electronic textiles (e‐textiles) that combine the wearing comfort of textiles and the functionality of soft electronics are highly demanded in wearable applications. However, fabricating robust high‐performance stretchable e‐textiles with good abrasion resistance and high‐resolution aesthetic patterns for high‐throughput manufacturing and practical applications remains challenging. Herein, the authors...
Literature reports have shown that in primary structures, single‐atom catalysts exhibit better performance than cluster and nanoparticles due to their maximum atom utilization and the fine‐tuning of the electronic structure of the active sites. Hierarchical structures have recently been extensively studied because of increased active sites and orderliness of channels significantly improves the catalytic...
