Converting carbon dioxide (CO2) into fuel and high‐value‐added chemicals is considered a green and effective way to solve global energy and environmental problems. Covalent triazine frameworks (CTFs) are extensively utilized as an emerging catalyst for photo/electrocatalytic CO2 reduction reaction (CO2RR) recently recognized for their distinctive qualities, including excellent thermal and chemical...
Non‐aqueous solvents, in particular N,N‐dimethylaniline (NMP), are widely applied for electrode fabrication since most sodium layered oxide cathode materials are readily damaged by water molecules. However, the expensive price and poisonousness of NMP unquestionably increase the cost of preparation and post‐processing. Therefore, developing an intrinsically stable cathode material that can implement...
Lithium, is the most ideal anode material for lithium‐based batteries. However, the overgrowth of lithium dendrites and the low lithium‐ion diffusion rate at low temperatures limit the further application of lithium metal anodes. Here, the applied magnetic field is introduced inside the lithium metal anode by using a novel magnetic metal‐organic framework as a current collector. The magnetic field...
Metalloporphyrin Conjugates
In article number 2301596, Matteo Tommasini, Juan Cabanillas‐González, and co‐workers reveal the photophysics of a fused nanographene–metalloporphyrin. The diagram shows the unveiled relaxation pathways of excited states. Photoexcitation populates ligand‐centered singlets, transitioning via intersystem crossing to metal‐centered triplets, then relaxing to ligand‐centered...
Porphyrins, a type of heterocyclic aromatic compounds consisting of tetrapyrroles connected by four substituted methine groups, are appealing building blocks for solar energy applications. However, their photosensitization capability is limited by their large optical energy gap, which results in a mismatch in absorption toward efficient harvesting of the solar spectrum. Porphyrin π‐extension by edge‐fusing...
Fiber‐based supercapacitors (FSCs) possess great potential as an ideal type of power source for future weaveable/wearable electronics and electronic‐textiles. The performance of FSCs is, without doubt, primarily determined by the properties of fibrous electrodes. Carbonaceous fibers, e.g., commercial carbon fibers, newly developed graphene fibers, and carbon nanotube fibers, are deemed as promising...
Although there has been tremendous progress in exploring new configurations of zinc‐ion hybrid supercapacitors (Zn‐HSCs) recently, the much lower energy density, especially the much lower areal energy density compared with that of the rechargeable battery, is still the bottleneck, which is impeding their wide applications in wearable devices. Herein, the pre‐intercalation of Zn2+ which gives rise...
Increasing the mass loading of transition metal single atoms coordinated with nitrogen in carbon‐based materials (M‐N‐C) is still challenging. Herein, inspired by the bioconcentration effect in the living body, a biochemistry strategy for the synthesis of Fe‐N‐C single atoms is demonstrated. Through introducing ferrous glycinate into the growth of fungus, the Fe atoms are bioconcentrated in hyphae...
As an essential member of 2D materials, MXene (e.g., Ti3C2Tx) is highly preferred for energy storage owing to a high surface‐to‐volume ratio, shortened ion diffusion pathway, superior electronic conductivity, and neglectable volume change, which are beneficial for electrochemical kinetics. However, the low theoretical capacitance and restacking issues of MXene severely limit its practical application...
Monodisperse AIE (aggregation‐induced emission)‐active conjugated polymer nanoparticles are synthesized by dispersion polymerization using geminal Suzuki cross‐coupling of 1,1‐dibromoolefins. The size of the nanoparticles can be adjusted by varying the concentration of the initial monomer.
