Regulating electrochemical performance of Cu_(7)S_(4) electrodes via ligand engineering in copper cluster precursors

Nano Research 2024年第11期17卷 9746-9755页

作者： Zhou Wu Lu-Fan Wang Xiao-Fei Liu Ren-Wu huang Rui Wang Guoqiang Sun shuang-quan Zang Henan Key Laboratory of Crystalline Molecular Functional Materials College of Chemistry Zhengzhou University Zhengzhou 450001 China

Cu-based chalcogenide materials exhibit significant promise for the development of Zn-metal-free anode materials for aqueous Zn-ion batteries (AZIBs). Here, we present the establishment of an efficient and universal strategy that capitalizes on the pyrolysis of copper nanoclusters to fabricate conversion-type Cu_(7)S_(4) anodes engineered for AZIBs, showcasing outstanding electrochemical performance. Furthermore, by exploiting ligand engineering, we enable the precise control of both the type of molecular fragments generated during nanocluster pyrolysis, thus enabling the manipulation of vacancy concentrations and ion/electron migration in the resultant pyrolysis products. In contrast to the direct pyrolysis of metal salts and ligands, the products derived from copper nanoclusters exhibit enhanced specific capacity, rate performance, and overall stability. This research offers valuable insights for the development of novel electrode materials through the pyrolysis of atomically precise nanoclusters.

Controllable construction of yolk–shell Sn–Co@void@C and its advantages in Na-ion storage

引用

Rare Metals 2021年第9期40卷 2392-2401页

作者： shuang Liu Xin-Ze Li Bin huang Jian-Wen Yang quan-Qi Chen Yan-Wei Li Shun-Hua Xiao Guangxi Key Laboratory of Electrochemical and Magneto-Chemical Functional Materials College of Chemistry and BioengineeringGuilin University of TechnologyGuilin 541004China

In the family of anodes for sodium-ion batteries,alloy-type anodes possess higher theoretical specific capacity than carbon anodes. The theoretical specific capacity of metallic Sn is 847 mAh·g^(-1). However, the tinbased material undergoes a large volume expansion during the sodium-ion intercalation process, which leads to the crack and pulverization of the electrode, consequently resulting in a significant capacity loss. In this paper, a yolk–shell-structured Sn–Co@void@C composite composed of a Sn–Co alloy core, a carbon shell and void space between the core and shell is designed and *** with the carbon-encapsulated SnCo without void space(Sn–Co@C) and carbon-encapsulated pure Sn core shell with void space(Sn@void@C), this composite exhibits improved reversibility, cyclic performance and rate capability. This work highlights the important roles of Co in the alloy and the void space between the core and the shell. The former can not only buffer the volume expansion of Sn, but also act as an electrical conductor. The void space can further tolerate the volume expansion of the Sn–Co core. Owing to this unique microstructure, the Sn–Co@void@C composite shows an initial reversible capacity of 591.4 mAh·g^(-1), at a current density of50 mA·g^(-1). After 100 charge/discharge cycles at100 mA·g^(-1), the composite still delivers 330 mAh·g^(-1).

Chinese Chemical Letters 2009年第5期20卷 627-630页

作者： Bao quan huang College of Chemistry & Material Science Fujian Normal University Fuzhou 350007 China

A novel axially substituted silicon（IV） phthalocyanine, namely di-pyridyloxy axially substituted silicon（IV） phthalocyanine 2 was synthesized and characterized by UV/vis, IR, elemental analysis, MS as well as IH NMR spectroscopy. Hydrophobic 2 was encapsulated by amphiphilic triblock copolymer poly[N^e-（benzyloxycarbonyl-lysine]-poly（ethylene glycol）-poly [N^e-（benzyl oxycarbonyl）（PLL（Z）-b-PEG-b-PLL（Z）） to form hydrophobic 2-loaded polymeric complex micelle （PIC）（2-loaded P/C）. Atom force microscopy （AFM） image showed that 2-loaded PIC formed a spherical nanocarrier with approximately 35-50 nm in diameter. The fluorescence intensity and lifetime of 2-loaded PIC was significantly enhanced bv the incorporation 2 into PIC nanocarrier.

作者： Ya-Hui Li Ren-Wu huang Peng Luo Man Cao Hong Xu shuang-quan Zang Thomas C.W.Mak College of Chemistry and Molecular Engineering Zhengzhou University Department of Chemistry The Chinese University of Hong Kong Shatin

A new 1D silver cluster-assembled complex Ag_(10)bpy-CH_3CN exhibiting intense photoluminescence was reported. Upon the loss of coordinated acetonitrile, Ag_(10)bpy-CH_3CN form Ag_(10)bpy with Ag_(10)S_6 cores slightly distorted, being accompanied with photoluminescence quenching. Inverse process can be realized by treating Ag_(10)bpy with acetonitrile and shows a selectively erasable photoluminescent switch.
