Dimensional effects of nanostructured Mg/MgH2 for hydrogen storage applications: A review

Excellent catalysis of Mn3O4 nanoparticles on the hydrogen storage properties of MgH2: an experimental and theoretical study

“…Faced with a global energy crisis and environmental issues, the world is crying out for sustainable clean energy sources. [1][2][3] Hydrogen, which can generate electricity via fuel cells with nearly no emission of pollutants, is regarded as one of the most promising substitutes for fossil fuels. [4][5][6] In order to store and transfer hydrogen conveniently, efficiently and safely, hydrogen storage materials with a moderate operating temperature, low cost, good dynamics and high hydrogen storage density are urgently required.…”

Ca0.5Mg0.5Co2O4 Nanosheets Comprised of Nanoparticles, Synthesis, Characterization and their Catalytic Activity in the Hydrolysis of Ammonia Borane for Hydrogen Production

“…Hydrogen is regarded as an ideal energy carrier, which has several advantages including its high energy density, together with the environmental benign nature [1,2]. Recently, different methods have been developed and implemented to produce hydrogen [3][4][5][6][7]. Among them, the production of hydrogen by the catalytic dehydrogenation of ammonia borane (AB, NH 3 BH 3 ) in aqueous solution has received special attention because AB is an excellent hydrogen-storage material with a high gravimetric hydrogen content of up to 19.6 wt% (nearly 5 times higher than that of traditional metal hydride materials).…”

Hydrogen Energy paper 15

“…The main 15 disadvantages of MgH2 based hydrogen storage is, as mentioned above, the high 16 temperature of hydrogen desorption (> 673 K) and high reactivity toward air and oxygen [7, 17 8]. The technology in research progress in order to improve hydrogen storage of MgH2/Mg 18 can be classified into four categories: alloying, nanoscaling, nanoconfinement, and 19 additive-addition [9,10]. Among current technologies, the ball milling/mechanical milling 20 has shown a potential for improving surface and kinetic properties of MgH2/Mg due to 21 several changes by the introduction of structural defects, phase change and crystallinity …”
