Lithium- or potassium-doped carbon nanotubes can absorb ∼20 ∼14 weight percent of hydrogen at moderate (200° to 400°C) room temperatures, respectively, under ambient pressure. These values are greater than those metal hydride and cryoadsorption systems. The stored in the lithium- be released higher sorption-desorption cycle repeated with little decrease sorption capacity. high hydrogen-uptake capacity these systems may derived from special open-edged, layered structure made methane, as well...
Magnesium hydride owns the largest share of publications on solid materials for hydrogen storage. The group international experts contributing to IEA Task 32 Hydrogen Based Energy Storage recently published two review papers presenting activities focused magnesium based and Mg compounds energy This article not only overviews latest both fundamental aspects Mg-based hydrides their applications, but also presents a historic overview topic outlines projected future developments. Particular...
The ever-increasing demand for energy coupled with dwindling fossil fuel resources make the establishment of a clean and sustainable system compelling need. Hydrogen-based systems offer potential solutions. Although, in long-term, ultimate technological challenge is large-scale hydrogen production from renewable sources, pressing issue how to store efficiently on board fuel-cell vehicles1, 2.
Ternary imides of Li–Mg and Li–Ca were synthesized tested for hydrogen storage. Li2MgN2H2, as an example, reversibly stores 5.5 wt.-% at temperatures below 180 °C (see Figure) with relatively high desorption plateau pressures. The present work also reveals the significance chemical reactions between amides ionic hydrides in design synthesis novel metal–N–H systems Supporting information this article is available on WWW under http://www.wiley-vch.de/contents/jc_2089/2004/c0571_s.pdf or from...
Carbon nanotubes prepared by catalytic (CO) disproportionation were studied using TEM, XRD, UPS, XPS, and optical spectroscopies. In comparison with graphite, the carbon show greater interplanar distance, smaller work function, steeper Fermi edge, negative core-level shift, stronger plasma excitation. Their valence band is basically same as that of lower intensity in binding energy region 2--7 eV. The exhibit a strong limiting effect, superior to both black ${\mathrm{C}}_{60}$.
Pure lithium amide (LiNH2) decomposes to imide and ammonia at temperatures above 300 °C. Lithium hydride, on the other hand, liberates hydrogen 550 By thoroughly mixing these two substances conducting temperature-programmed desorption (TPD), we noticed that was produced around 150 Combined thermogravimetric (TG), X-ray diffraction (XRD), infrared (IR) analysis revealed would react with hydride convert (or Li-rich imide). The reaction mechanism investigated by isotopic exchange.
Highly regulated core–shell Fe3O4–poly(3, 4-ethylenedioxythiophene) (PEDOT) microspheres were successfully synthesized by a two-step method in the presence of polyvinyl alcohol (PVA) and p-toluenesulfonic acid (p-TSA). And their morphology, microstructure, electromagnetic microwave absorbing properties subsequently characterized. By simply adjusting molar ratio 3, 4-ethylenedioxythiophene (EDOT) to Fe3O4 (represented (EDOT)/(Fe3O4)), thickness polymer shell can be tuned from tens hundreds...
Liquid hydrogen carriers are considered to be attractive storage options because of their ease integration into existing chemical transportation infrastructures when compared with liquid or compressed hydrogen. The development such forms part the work International Energy Agency Task 32: Hydrogen-Based Storage. Here, we report state-of-the-art for ammonia-based and organic carriers, a particular focus on challenge ensuring easily regenerable, high-density storage.
Development of non-noble metal catalysts with similar activity and stability to noble metals is significant importance in the conversion utilization clean energies.
The development of cost-effective and highly efficient catalysts is scientific importance practical need in the conversion utilization clean energy. One strategies fulfilling that demand to achieve high exposure a catalytically functional noble metal reactants maximize its efficiency.
