چکیده
Abstract The main obstacle that hinders the application of fuel cell fuels for vehicles today is hydrogen storage tube. Therefore, this paper will report results a study on MgH 2 -based materials with Fe O 3 catalyst inserted (5 wt%, 10 15wt%) and prepared by mechanical alloying technique hours. samples were obtained from Lhoong Setia Mining site in Jantang Village, Lhoong, Aceh Besar. initial sample separation process was carried out manually using bar magnet. Furthermore, hematite extraction addition 1M HCL NaOH each. Then milling -Fe planetary ball mill. X-ray diffraction test showed phase most dominant/mainstream phase. Thermal testing DSC H desorption experienced decrease temperature 194.56 °C time variation 7

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
15 صفحه اولPotential of AlN nanostructures as hydrogen storage materials.
The capability of AlN nanostructures (nanocages, nanocones, nanotubes, and nanowires) to store hydrogen has been studied using gradient-corrected density functional theory. In contrast to bulk AlN, which has the wurtzite structure and four-fold coordination, the Al sites in AlN nanostructures are unsaturated and have two- and three-fold coordination. Each Al atom is capable of binding one H(2) ...
متن کاملCovalent organic frameworks as exceptional hydrogen storage materials.
We report the H2 uptake properties of six covalent organic frameworks (COFs) from first-principles-based grand canonical Monte-Carlo simulations. The predicted H2 adsorption isotherm is in excellent agreement with the only available experimental result (3.3 vs 3.4 wt % at 50 bar and 77 K for COF-5), also reported here, validating the predictions. We predict that COF-105 and COF-108 lead to a re...
متن کاملHydrazine Borane and Hydrazinidoboranes as Chemical Hydrogen Storage Materials
Hydrazine borane N2H4BH3 and alkali derivatives (i.e., lithium, sodium and potassium hydrazinidoboranes MN2H3BH3 with M = Li, Na and K) have been considered as potential chemical hydrogen storage materials. They belong to the family of boronand nitrogen-based materials and the present article aims at providing a timely review while focusing on fundamentals so that their effective potential in t...
