Hydrogen energy is one of the ideal energy alternatives and the upstream of the hydrogen industry chain is hydrogen production,which can be achieved via the reaction of inorganic materials with water,known as *** inorganic materials,the high hydrogen capacity for hydrolysis of MgH2（15.2 wt%）makes it a promising material for hydrogen production via ***,the dense Mg（OH）2passivation layer will block the reaction between MgH2and the solution,resulting in low hydrogen yield and sluggish hydrolysis *** this work,the hydrogenyield and hydrogen generation rate of MgH2are considerably enhanced by adding Ti-Zr-Fe-Mn-Cr-V high-entropy alloys（HEAs） for the first *** *** MgH2-3 wt% TiZrFe1.5MnCrV0.5(labelled as MgH2-3 wt% Fe1.5) composite releases 1526.70 mL/g H2within 5 min at 40℃,and the final hydrolysis conversion rate reaches 95.62% within 10 *** mean hydrogen generation rate of the MgH2-3 wt% Fe1.5composite is 289.16 mL/g/min,which is 2.38 times faster than that of pure ***,the activation energy of the MgH2-3 wt% Fe1.5composite is calculated to be 12.53 kJ/mol. The density functional theory（DFT） calculation reveals that the addition of HEAs weakens the Mg-H bonds and accelerates the electron transfer between MgH2and HEAs,Combined with the cocktail effect of HEAs as well as the formation of more interfaces and micro protocells,the hydrolysis performance of MgH2is considerably *** work provides an appealing prospect for real-time hydrogen supply and offers a new effective strategy for improving the hydrolysis performance of MgH2.

MgH_(2)has a high theoretical hydrogen production capacity and mild conditions for hydrogen production by hydrolysis,so it is suitable as an ideal hydrogen source for fuel ***,with the progress of the hydrolysis reaction,MgH_(2)is impeded from reacting further by the continuous deposition of magnesium hydroxide on its surface,resulting in low hydrogen yield and slow reaction *** the present work,a highly efficient NiCo bimetallic synergistic catalysis is developed to improve the hydrolysis performance of MgH_(2).The MgH_(2)-8 wt%NiCo@C composite ball-milled for 5 h achieves nearly 100%hydrogen desorp-tion efficiency within 15 min in 0.05 mol L^(-1)MgCl_(2)*** the interaction between Ni and Co on the surface of MgH_(2)can form a channel for rapid hydrogen evolution,which hinders the continuous formation of the Mg(OH)_(2)passivation layer and promotes the hydrolysis reaction of MgH_(2).This is very important for the implementation of MgH_(2)hydrolysis to produce hydrogen in the future.

以球磨法制备镁基储氢材料,并作为供氢体对噻吩进行加氢脱硫研究。程序升温脱附(TPD)和差示扫描量热(DSC)测试表明,材料放氢峰温为320℃,可与噻吩加氢温度匹配。噻吩加氢脱硫实验表明,当反应温度为350℃时,噻吩加氢反应转化率最高;反应温度继续升高,转化率则随之下降。加氢脱硫反应产物分析表明,由于温度升高,储氢材料中的活性氢将直接结合生成氢气分子,从而使加氢反应较难进行,噻吩转化率下降。第一性原理计算结果表明,MgH_2直接对噻吩加氢的能量位垒为62.65kJ/mol,而由MgH_2所放出的氢气对噻吩加氢的2个位垒为275.36kJ/mol和365.36kJ/mol。MgH_2与噻吩直接反应更有利于加氢脱硫反应的进行。
