Cyano‐rich g‐C3N4 materials are widely used in various fields of photochemistry due to the very powerful electron‐absorbing ability and electron storage function of cyano, as well as its advantages in improving light absorption, adjusting the energy band structure, increasing the polarization rate and electron density in the structure, active site concentration, and promoting oxygen activation ability...
The current development of single electrocatalyst with multifunctional applications in overall water splitting (OWS) and zinc–air batteries (ZABs) is crucial for sustainable energy conversion and storage systems. However, exploring new and efficient low‐cost trifunctional electrocatalysts is still a significant challenge. Herein, the antiperovskite CuNCo3 prototype, that is proved to be highly efficient...
Orthorhombic MoO3 (α‐MoO3) with multivalent redox couple of Mo6+/Mo4+ and layered structure is a promising cathode for rechargeable aqueous Zn‐ion batteries (AZIBs). However, pure α‐MoO3 suffers rapid capacity decay due to the serious dissolution and structural collapse. Meanwhile, the growth of byproduct and dendrite on the anode also lead to the deterioration of cyclic stability. This article establishes...
Potassium‐ion batteries (PIBs) have attracted more and more attention as viable alternatives to lithium‐ion batteries (LIBs) due to the deficiency and uneven distribution of lithium resources. However, it is shown that potassium storage in some compounds through reaction or intercalation mechanisms cannot effectively improve the capacity and stability of anodes for PIBs. The unique anti‐spinel structure...
Amination of aryl chlorides by metallaphotocatalysis is highly desired but remains practically challenging. Meanwhile, relying on soluble noble‐metal photocatalysts suffers from resource scarcity and structural instability which limit their practical application. Here in, a highly crystalline acetylene‐based hydrazone‐linked covalent organic framewok‐1 (AC‐COF‐1) is reported that enables metallaphotocatalytic...
Nitrate is a reasonable alternative instead of nitrogen for ammonia production due to the low bond energy, large water‐solubility, and high chemical polarity for good absorption. Nitrate electroreduction reaction (NO3RR) is an effective and green strategy for both nitrate treatment and ammonia production. As an electrochemical reaction, the NO3RR requires an efficient electrocatalyst for achieving...
Synergetic Prostate Cancer Therapies
In article number 2207077, Li Zhang, Yunjiao Zhang, Chaozhao Liang, and co‐workers propose intratumoral implantation of micromagnets to actively attract intravenously‐injected magnetic PEGylated manganese‐zinc ferrite nanocrystals (PMZFNs) from blood vessels into tumor tissue. PMZFNs exert relatively durable tumoricidal effects by inducing ferroptotic/immunogenic...
Therapeutic efficacy for prostate cancer is highly restricted by insufficient drug accumulation and the resistance to apoptosis and immunogenic cell death (ICD). Although enhanced permeability and retention (EPR) effect of magnetic nanomaterials could benefit from external magnetic field, it falls off rapidly with increased distance from magnet surface. Considering the deep location of prostate in...
The chemical generation of singlet oxygen (1O2) by the MoO42−‐catalyzed disproportionation of hydrogen peroxide (H2O2) has been widely applied in numerous catalytic processes; however, such molybdate ions cannot be administered for redox‐based cancer therapeutics. This work reports the albumin‐mediated biomimetic synthesis of highly active molybdenum sulfide (denoted MoB) nanocatalysts that mediate...
Flexible aqueous zinc batteries are promising candidates as safe power sources for fast‐growing portable and wearable electronics. However, the low working voltage, poor rate capability, and cycling stability have greatly restricted their development and applications. Here, a new family of flexible bimetallic phosphide/carbon nanotube hybrid fiber electrodes with unique macroscopic microcrack structure...

In article number 2206338, Yang Zhao and co‐workers report a high‐performance flexible aqueous zinc battery based on hybrid fiber electrode with hierarchical microcrack structure. The unique structure can not only facilitate the penetration of electrolyte for fast charge transfer, but also relieve the stress concentrations under deformations. The fabricated flexible...
Sodium‐based dual‐ion batteries (SDIBs) have become a new type of energy storage device with great application value because of their high operating voltage, high energy density, and low cost. However, transition‐metal dichalcogenide (TMD) anodes show unsatisfactory Na+ electrochemical performance owing to the low intrinsic conductivity and inferior ion transport kinetics. Here, an elaborate design...

Adequately harvesting all excitons in a single molecule and inhibiting exciton losses caused by intermolecular interactions are two important factors for achieving high efficiencies thermally activated delayed fluorescence (TADF).
