Tuning single-phase medium-entropy oxides derived from nanoporous NiCuCoMn alloy as a highly stable anode for li-ion batteries

引用

稀有金属:英文版 2023年第9期42卷 2982-2992页

作者： Zhen-Yang Yu Qi Sun Hao li Zhi-Jun Qiao wei-jie li Shu-Lei Chou Zhi-Jia Zhang Yong Jiang School of Mechanical Engineering Tiangong UniversityTianjin300387China State Key Laboratory for Powder Metallurgy Central South UniversityChangsha410083China School of Material Science and Engineering Tiangong UniversityTianjin300387China School of Electronic and Information Engineering Institute of Quantum Materials and DevicesTiangong UniversityTianjin300387China

Incorporating four cations into a single-phase oxide is beneficial for maintaining structural stability during li+insertion/desertion because of the produced entropy-dominated phase stabilization effects. However,medium-entropy oxides exhibit inherently poor electron and ion conductivity. As such, in this work, a single-phase medium-entropy oxide of Ni_(x)Cu_(y)CozMn_(1-x-y-z)O(named as NCCM@oxides(H_(2))) is prepared by modified-NiCuCoMn alloy through the epitaxial-growing-based self-combustion and hydrogen reduction. During hydrogen reduction, some Cu ions are reduced to elemental Cu(defined as Cu^(0)),which is distributed among the metal oxides, while generating extensive oxygen vacancies around Cu. The synergetic effect between nanoporous metal-core oxide-shell structure and enriched oxygen/Cu^(0) vacancies greatly enhances the electronic/ionic conductivity. In addition, the lattice of single-phase quaternary metal oxides has the configuration entropy stability, which enables the rock-salt structure to remain stable during repeated conversion reactions. Benefiting from the above-mentioned merits, the anodeforli-ionbatterieswithentropy-stabled NCCM@oxides(H_(2)) composite shows a high specific capacity of 699 mAh·g^(-1) at 0.1 A·g^(-1) and ultra-stable cycling stability, which maintains 618 and 489 mAh·g^(-1) at 0.1 and 1.0 A·g^(-1) after 200 cycles, respectively. This is the first use of this novel and simple strategy for modifying medium-entropy oxides, which paves the way for the development of high-entropy oxides as high-performance electrodes.

Ethanol steam reforming over Ni-Cu/Al_2O_3-M_yO_z (M = Si, La, Mg,and Zn) catalysts

Journal of Natural Gas Chemistry 2009年第1期18卷 55-65页

作者： lifeng Zhang jie liu wei li Cuili Guo Jinli Zhang School of Chemical Engineering and Technology Tianjin University Tianjin 300072 China

Ni-based catalysts doped with copper additives were studied on their role in ethanol steam reforming reaction. The effects of Cu content, support species involving Al2O3-SIO2, Al2O3-MgO, Al2O3-ZnO, and Al2O3-La2O3, on the catalytic performance were studied. Characterizations by TPR, XRD, NH3-TPD, XPS, and TGA indicated that catalysts 30Ni5Cu/Al2O3-MgO and 30Ni5Cu/Al2O3-ZnO have much higher H2 selectivity than 30Ni5Cu/Al2O3-SiO2, as well as good coke resistance. H2 selectivity for 30Ni5Cu/Al2O3-MgO catalyst was 73.3% at 450 ℃ and increased to 94.0% at 600℃, whereas for 30Ni5Cu/Al2O3-ZnO catalyst, the H2 selectivity was 63.6% at 450 ℃ and 95.2% at 600℃. TheseAl2O3-MgO and Al2O3-ZnO supported Ni-Cu bimetallic catalysts may have important applications in the production of hydrogen by ethanol steam reforming reactions.

Development of Biomimetic Needle-like Apatite Nanocrystals by a Simple New Method

引用

Journal of Materials Science & Technology 2004年第6期20卷 665-667页

作者： jie wei, Yubao li, Yi ZUO, Xueling PENG and li ZHANGResearch Center for Nano-Biomaterials, Sichuan University, Chengdu 610064, China Res. Ctr. for Nano-Biomaterials Sichuan Univ. Chengdu 610064 China

A new method of calcium nitrate and sodium phosphate as reactants was employed to prepare biomimetic apatite nanocrystals by a simple heating treatment in water. The structure and properties of the apatite crystals were investigated by TEM, XRD, IR, ICP and TG. It is found that the apatite nanocrystals contain OH-, CO32-, Na+ and HPO42- ions in their crystal structure. The crystal water is removed during heating from 200℃ to 400℃. CO32-and HPO42- are decomposed at 600℃ to 800℃, also there is lattice vvater lost at this temperature stage. The morphology of the apatite nanocrystals is needle-like with a length less than 80 nm. The size and crystallinity of the apatite nanocrystals increase with vvater treatment temperature and time. Compared to the apatite crystals sintered at 800℃, water treated apatite nanocrystals are poorly crystallized apatite. The results indicate that the apatite nanocrystals have similarity in composition, structure, morphology and crystallinity to that of bone apatite crystals. It can be used to make apatite crystals/polymer biomimetic bone repair materials or for other biomedicai applications.

Effects of carbon on electrochemical performance of red phosphorus(P) and carbon composite as anode for sodium ion batteries

引用

Journal of Materials Science & Technology 2021年第9期68卷 140-146页

作者： Zhi-Jia Zhang wei-jie li Shu-Lei Chou Chao Han Hua-Kun liu Shi-Xue Dou State Key Laboratory of Separation Membrane and Membrane Processes.Tianjin Municipal Key Laboratory of Advanced Fibers and Energy Storage School of Materials Science and EngineeringTiangong UniversityTianjin 300387China Institute for Superconducting and Electronic Materials University of WollongongWollongongNSW2522Australia School of Civil and Environmental Engineering Faculty of Engineering and Information TechnologyUniversity of Technology Sydney.SydneyNSW2007Australia

Red phosphorus/graphite(P/G) and red phosphorus/carbon nanotube(P/CNT) composites were prepared by ball milling red phosphorus with CNTs and graphite, respectively. The electrochemical results show superior electrochemical performances of the P/G and P/CNT composites compared with that of the reference sample milled with Super-P carbon. After 70 cycles, the P/G and P/CNT composites remained771.6 and 431.7 mA h g^(-1), with 68 % and 50 % capacity retention, respectively. With increasing the milling time(20 h), CNTs were cut into short pieces and then broken into carbon rings and sheets which were well mixed with red phosphorus. The morphology of the P/CNT composite can buffer the large volume changes from alloying and de-alloying during cycling, resulting in the enhanced cycling stability.
