Photosensitive materials, such as energetic complexes, usually have high sensitivity and cause heavy‐metal pollution, whereas others, like carbon black and dye, do not contain energy, which affects energy output and mechanical properties. In this work, donor–acceptor π‐conjugated energetic catalysts, denoted as D‐n, are designed and synthesized. Nonmetallic hybrid energetic composites are prepared...
Metal‐Free Hybrid Energetic Composites
Donor–acceptor π‐conjugated energetic catalysts, denoted as D‐n, are developed, and nonmetallic hybrid energetic composites are prepared by assembling the as‐synthesized catalysts into multiscale ammonium perchlorate (AP), which can be ignited without the involvement of metals. At the voltage of 1 kV, the laser‐ignition delay time of D‐2/AP decreases from 56...
Multiresponsive flexile sensors with strain, temperature, humidity, and other sensing abilities serving as real electronic skin (e‐skin) have manifested great application potential in flexible electronics, artificial intelligence (AI), and Internet of Things (IoT). Although numerous flexible sensors with sole sensing function have already been reported since the concept of e‐skin, that mimics the...
At present, it is still a great challenge to synthesize refractory Pt‐based electrocatalysts with excellent active specific surface area, specific activity, and stability by a simple method. Here, a superfast and solvent‐free microwave strategy is reported to synthesize refractory ultrafine (≈3 nm) Pt–lanthanide@Ketjen Black (PtM@KB, M = La, Gd, Tb, Er, Tm, and Yb) alloy with densely packed as efficient...
The organic–inorganic hybrid perovskite solar cells present a rapid improvement on power conversion efficiency from 3.8% to 25.5% in the past decades. Owing to the tuneable bandgaps, low‐cost, and ease of fabrication, perovskites become ideal candidate materials for fabricating tandem solar cells, especially for efficient and high‐voltage monolithic two‐terminal devices. In this review, an overview...
Flexible energy storage electronics have gained increasing attention in recent years, but the simultaneous acquiring of high volumetric and high areal capacities as well as excellent flexibility in order to truly implement wearable and portable electronics in practice remains challenging. Here, a conductive and highly deformable freestanding all‐pseudocapacitive paper electrode (Ti3C2Tx/MnO2 NWs)...
Sodium‐ion batteries (SIBs) have attracted tremendous interest and become a worldwide research hotpot owing to their low cost and abundant resources. To obtain suitable anode materials with excellent performance for SIBs, an effective and controllable strategy is presented to fabricate SnS2 nanosheets coating on nanohollow cubic CoS2/C (CoS2/C@SnS2) composites with a hollow structure using Co‐metal‐organic...
In article number 1802716, Caizhen Zhu and co‐workers develop an effective and controllable strategy for preparing a SnS2 nanosheet coating on nano‐hollow cubic CoS2/C (CoS2/C@SnS2). As anodes for sodium‐ion batteries, the electrode exhibits an ultra‐long cycle life and excellent rate performance. This strategy can pave a way for preparing various metal sulfides with excellent performance in the field...
Enrichment of molecular photosensitizers and catalysts in a confined nanospace is conducive for photocatalytic reactions due to improved photoexcited electron transfer from photosensitizers to catalysts. Herein, the self‐assembly of a highly stable 3D supramolecular organic framework from a rigid bipyridine‐derived tetrahedral monomer and cucurbit[8]uril in water, and its efficient and simultaneous...
