“…However, MgH 2 has been used as the starting chemical with an amide to produce lightweight metal-based hydrogen storage materials [13][14][15]. MgH 2 can also be used in portable fuel cells, wherein it undergoes hydrolysis with pure water to produce 15.2 mass% of hydrogen [16,17]. Another example of the mobile application for MgH 2 is that it is used as a negative electrode in Li- [19,20].…”

ABSTRACT:This paper describes the direct synthesis of magnesium hydride (MgH 2 ) nanofibers by hydriding chemical vapor deposition (HCVD), in which the effect of hydrogen pressure on the production rate, the composition and the shape of products obtained were examined by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET). The XRD patterns showed that the main product in each case was MgH 2 ; in particular, the products formed at 2, 3 and 4 MPa were highly pure. In contrast, at a hydrogen pressure of 1 MPa, unhydrided Mg was deposited along with MgH 2 . The SEM images also revealed orientation of the as-deposited products; higher pressures of 3 and 4 MPa caused the formation of straight and curved nanofibers, and lower ones of 1 and 2 MPa, highly curved nanofibers and nanorods with a few straight nanofibers. With pressurizing hydrogen, not only the BET specific surface areas of the products but also the production rate increased. The results also appealed that HCVD could control the shape/size of MgH 2 nanofibers by changing the pressure via only a single operation.

“…More recently, these researches were enhanced and this is reflected in an increased number of publications and patents that are directed to the hydrogen production, through reactions between water and aluminum based metal [5][6][7]. All of the aluminum based approaches propose activation methods to remove the protective layer of aluminum oxide, thus allowing the hydrolysis reaction to start and proceed.…”

“…One way of perspective is based on the generation of hydrogen [1][2][3]. Hydrogen is known as one of the best clean energy carrier because of its minimal impact on the environment regarding to greenhouse gas emissions such as carbon dioxide and other gases [1,[4][5][6]. Hydrogen can be used directly in molecular form , (i.e.…”

“…Hydrogen can be used directly in molecular form , (i.e. as a fuel for vehicles) or indirectly to generate electricity for other industrial applications [4][5][6][7] .A major advantage which it has over other fuels is that not cause pollution because of its burning reaction results only water. Hydrogen is also an almost ideal fuel gas and in terms of reducing smog when it is burned.…”

“…Therefore, in situ production of hydrogen is extremely essential, especially in the aspect of emergency power units needed in disaster areas, portable electronic devices, on-board vehicles etc. [3][4][5][6] Recently, aluminum alloy has been identi ed as the most promising materials to generation hydrogen from water. Aluminum alloys have high gravimetric and volumetric energy density, low costs and non-toxic reaction by-product [7][8][9] .…”

Enhanced Hydrogen Generation Properties of Al-Ga-In-Sn Alloy in Reaction with Water by Trace Amount of AlTi<sub>5</sub>B Additives

Al-3Ga-3In-Sn (mass%) alloy with a little amount of AlTi 5 B as re ner was fabricated using a simple smelting and casting method. The phase compositions and microstructure were investigated by means of XRD and SEM with EDX. The hydrogen generation property of Al-GaIn-Sn alloy with water was investigated. The results show that the Al grains and GIS (Ga-In-Sn) particles are re ned and more uniform with adding AlTi 5 B to Al-Ga-In-Sn alloy. Al grains size decrease from 120 μm to 40 μm and the GIS particles are re ned to 1 μm respectively. The hydrogen generation rate of Al-3Ga-3In-Snalloy with 0.1 mass%AlTi 5 B reaches 44 mL/min g at 30 C, and 460 mL/min g at 60 C, which is much higher than that of Al-3Ga-3In-Sn alloy. The high hydrogen generation rate is ascribed to the Al grain re nement and increasing amounts of GIS particle.
