Electronic textiles (e‐textiles) hold great promise for serving as next‐generation wearable electronics owing to their inherent flexible, air‐permeable, and lightweight characteristics. However, these e‐textiles are of limited performance mainly because of lacking powerful materials combination. Herein, a versatile e‐textile through a simple, high‐efficiency mixed‐dimensional assembly of 2D MXene...
Bifunctional Catalysts
In article number 2201974, Yunqi Liu, Xuan Yang, Xiang Feng, Yuan Pan, and co‐workers propose an encapsulation‐adsorption‐pyrolysis strategy for constructing Co‐Te diatomic sites with special CoN3C1‐TeN1C3 coordination structure anchored in N‐doped carbon, as efficient bifunctional catalysts for synergistic electrocatalytic hydrogen evolution and oxygen reduction. This work...
A encapsulation–adsorption–pyrolysis strategy for the construction of atomically dispersed Co‐Te diatomic sites (DASs) that are anchored in N‐doped carbon is reported as an efficient bifunctional catalyst for electrocatalytic hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR). The as‐constructed catalyst shows the stable CoN3C1‐TeN1C3 coordination structure before and after HER...
Therapeutics that can be activated by radiation in situ to enhance the efficacy of radiotherapy are highly desirable. Herein, 7‐Dehydrocholesterol (7‐DHC), a biosynthetic precursor of cholesterol, as a radiosensitizer, exploiting its ability to propagate the free radical chain reaction is explored. The studies show that 7‐DHC can react with radiation‐induced reactive oxygen species and in turn promote...
In this work, by combining the superiority of polyoxometalates (POMs) and catalytic single‐metal site Co of metalloporphyrin, a series of mixed‐valence POM‐based metal‐organic frameworks (MOFs) composites is synthesized by a post‐modification method. The electron‐transfer property of POM@PCN‐222(Co) composite is significantly enhanced owing to the directional electron‐transfer from POM to single‐metal...
By combining the superiority of polyoxometalate (POM) and single‐metal site Co in porphyrin, a POM‐based metal–organic framework composite has been constructed by Wen‐Wen He, Ya‐Qian Lan, Shengqian Ma, and co‐workers (article number 2100762). Directional electron transfer from POM to the single‐metal site Co in PCN‐222(Co) accelerates electron‐transfer efficiency thereby affording high electrocatalytic...
In article number 1702987, Cheng Zhong, Yida Deng, and co‐workers synthesize atomic layer Co3O4 nanosheets (1.6 nm thickness) by a simple solvothermal method with a controlled concentration of H2O2. The atomic layer Co3O4 nanosheets exhibit high bifunctional activity for the oxygen reduction reaction and oxygen evolution reaction, which is key to knittable Zn–air batteries. The batteries are successfully...
Flexible, wearable, and portable energy storage devices with high‐energy density are crucial for next‐generation electronics. However, the current battery technologies such as lithium ion batteries have limited theoretical energy density. Additionally, battery materials with small scale and high flexibility which could endure the large surface stress are highly required. In this study, a yarn‐based...
