This study evaluated hydrogen generation through the hydrolysis of an Al/NaBH4/Co/NaAlO2 system. Hydrogen generation performance can be altered by changing the Al/NaBH4 mass ratios, Co amount and NaAlO2 concentration. The optimized composite can achieve a hydrogen yield of more than 90% within...

A simple method of improving hydrogen generation from the reaction between highly activated Mg powder and water is established. The Mg–H2O reaction is found to become faster and more intense when magnesium is mixed with salts and subjected to by high-energy ball milling. Among the studied...

A new hydrogen generation material, Al–Ca alloy, is prepared by ball milling method. Results show the prepared Al–Ca alloy can react with to produce hydrogen, but its hydrogen yield is lower. NaCl addition can further greatly improve hydrogen generation of Al–Ca alloys. The amount of NaCl...

Hydrogen production based in the corrosion of light metals in water solutions is an interesting alternative. Among all of them, Mg is probably the most adequate metal for energetic purposes due to its high electron density and oxidation potential. A safe and environmental-friendly method of...

Hydrogen absorption and desorption properties in nanocrystalline LaMg2Ni are presented. Nanostructured phases have been obtained by milling grain coarse ingot and by mechanically alloying the parent elements. The structural and hydriding properties were examined by X-ray diffraction, thermal...

The reaction performance of activated Mg/CoCl2 has been studied relative to its storage time, temperature, RH (relative humidity), and storage methods. Activated Mg/CoCl2 was prepared via high-energy milling and characterised using SEM (scanning electron microscopy) and TG (thermogravimetric...

The recent advances on the effects of microstructural refinement and various nano-catalytic additives on the hydrogen storage properties of metal and complex hydrides obtained in the last few years in the allied laboratories at the University of Waterloo (Canada) and Military University of...

This article describes a Group (VI) modified Co-Zr-B amorphous nano alloys were prepared in situ ultrasound-assisted reduction by sodium borohydride in an aqueous solution. Co-Cr-Zr-B, Co-Mo-Zr-B and Co-W-Zr-B powders were characterized by XRD, FESEM, BET and ICP techniques. No distinct peak...

High purity hydrogen produced by hydrolysis of sodium borohydride can be used directly in (proton exchange membrane) PEM fuel cells for portable devices and automotive applications. The advantages of high storage capacity, quickly start, controllable reaction and mild condition, hydrogen...
