| 1 | Preparation and hydrogen storage properties of MgH2-trimesic acid-TM MOF(TM=Co,Fe) composites显示文摘Two kinds of metal-organic frameworks(MOFs) based on Co(Ⅱ) and Fe(Ⅱ) as metal ions and trimasic acid(TMA) as organic linker were synthesized. They were used to prepare corresponding Mg H2-TM MOF(TM = Co, Fe) composites via ball-milling. X-ray diffraction analyses show the formation of Mg2 Co and α-Fe phases in Mg H2-TMMOF composites after decomposition. Both of the well dispersed Mg2Co andα-Fe nanoparticles exhibit considerable catalytic efficiency in accelerating the sorption kinetics of Mg H2.The dehydrogenated MgH2-Fe MOF composite shows faster hydriding kinetics than the pure Mg H2 and Mg H2-CoMOF. Meanwhile, the apparent dehydrogenation activation energy(Ed) of the Mg H2-Co MOF and Mg H2-Fe MOF composites are 151.3 ± 9.4 and 142.3 ± 6.5 kJ/mol H2, both of which are lower than that of pure Mg H2(181.4 ± 9.2 kJ/mol H2). The improvement on the sorption kinetics of the Mg H2-TM MOF powders is mainly attributed to the catalytic effects of nano-sized Mg2 Co and α-Fe formed on the surface of Mg/Mg H2 particles. | Zhewen Ma Jianxin Zou Darvaish Khan Wen Zhu Chuanzhu Hu Xiaoqin Zeng Wenjiang Ding | 2019 | Journal of Materials Science & Technology2019，35，10： | 6 |
| 2 | Joining of C_f/SiBCN composite with two Ni-based brazing fillers and interfacial reactions显示文摘C_f/SiBCN ceramic composite was joined using Ni-19Cr-10Si(BNi5) and Ni-33Cr-24Pd-3.5Si-0.5B filler alloys at 1170 °C for 10 min. Two kinds of Ni-based filler alloys exhibited good wettability on the C_f/SiBCN composite, with a contact angle of 13° and 4°, respectively. The microstructures of the brazed joints were investigated by electron-probe microanalysis(EPMA), and three-point bend test was conducted for the joints at room temperature. When being brazed with BNi5 filler alloy, no evident reaction layer was observed at the surface of the joined composite, and the joint microstructure was characterized by Ni_2Si matrix with scatteringly distributing mixture compounds of Cr_(23)C_6, Ni_2Si and CrB. While Ni-Cr-Pd(Si,B)brazing alloy was used, a Cr_(23)C_6 reaction layer with a thickness of 11 μm was formed at the surface of the base composite. In the central part of the brazed joint, the phases were composed of Ni(Cr,Si) solid solution and complex compounds including Pd_2Si,(Ni,Pd)_2Si and Ni-B. The strength of C_f/SiBCN joint brazed with BNi5 filler alloy was 62.9 MPa at room temperature, whereas that with Ni-Cr-Pd(Si,B) filler alloy was at the same level. | Wenwen Li Bo Chen Yi Xiong Huaping Xiong Yaoyong Cheng Wenjiang Zou | 2017 | Journal of Materials Science & Technology2017，33，5： | 2 |

| 10 | Nanostructuring of Mg-Based Hydrogen Storage Materials:Recent Advances for Promoting Key Applications显示文摘With the depletion of fossil fuels and global warming,there is an urgent demand to seek green,low-cost,and high-efficiency energy resources.Hydrogen has been considered as a potential candidate to replace fossil fuels,due to its high gravimetric energy density(142 MJ kg^(-1)),high abundance(H_(2)O),and environmentalfriendliness.However,due to its low volume density,effective and safe hydrogen storage techniques are now becoming the bottleneck for the'hydrogen economy'.Under such a circumstance,Mg-based hydrogen storage materials garnered tremendous interests due to their high hydrogen storage capacity(~7.6 wt%for MgH_(2)),low cost,and excellent reversibility.However,the high thermodynamic stability(ΔH=-74.7 kJ mol^(-1)H_(2))and sluggish kinetics result in a relatively high desorption temperature(>300℃),which severely restricts widespread applications of MgH_(2).Nano-structuring has been proven to be an effective strategy that can simultaneously enhance the ab/de-sorption thermodynamic and kinetic properties of MgH_(2),possibly meeting the demand for rapid hydrogen desorption,economic viability,and effective thermal management in practical applications.Herein,the fundamental theories,recent advances,and practical applications of the nanostructured Mg-based hydrogen storage materials are discussed.The synthetic strategies are classified into four categories:free-standing nano-sized Mg/MgH_(2)through electrochemical/vapor-transport/ultrasonic methods,nanostructured Mg-based composites via mechanical milling methods,construction of core-shell nano-structured Mg-based composites by chemical reduction approaches,and multi-dimensional nano-sized Mg-based heterostructure by nanoconfinement strategy.Through applying these strategies,near room temperature ab/de-sorption(<100℃)with considerable high capacity(>6 wt%)has been achieved in nano Mg/MgH_(2)systems.Some perspectives on the future research and development of nanostructured hydrogen storage materials are also provided. | Li Ren Yinghui Li Ning Zhang Zi Li Xi Lin Wen Zhu Chong Lu Wenjiang Ding Jianxin Zou | 2023 | Nano-Micro Letters2023，15，7： | 0 |
