Processing of LiBH4 from its elements by ball milling method

摘要: Abstract Investigations of alternative renewable energy resources continue, with many studies concentrating on hydrogen storage. However, there are a few problems such as storage, transportation, delivery to the user and usage safely, be addressed facilitate commercialization wide hydrogen. The absorbed form within metal hydrides seems best solution this problem. Since Li is lightest metal, it has advantage stored amount mass ratio. LiBH4 production process was investigated using elemental Li, B H2. Spex type ball milling tungsten carbide, stainless steel zirconia vessels, used mix different under argon atmosphere. X-ray diffraction pattern demonstrated that LiB obtained. A system designed provide atmosphere 60 bars force into structure. FTIR analysis strongly indicated compound when mol ratio B/Li 0.214. Thermal decomposition heat flow experiments performed simultaneously DSC TGA techniques also indicate hydrogen-rich structure showing greater loss. One gram lithium borohydride sample released 1423 ml Ni catalyst while NiO caused 1972.94 ml gas desorption, equaling 90% theoretical yield commercial LiBH4. Indicating that, water can obtained by either or catalysts.
