Kinetics Enhancement, Reaction Pathway Change, and Mechanism Clarification in LiBH4 with Ti-Catalyzed Nanocrystalline MgH2 Composite
Source abstract
Abstract
A composite of 2LiBH 4 + nano-MgH 2 * (Ti-catalyzed) shows significantly enhanced desorption kinetics compared to a conventional mixture of 2LiBH 4 + MgH 2 . The desorption mechanism was studied in the temperature range between 304 and 383 °C and under different pressure conditions. Desorption temperatures are 50–70 °C lower compared to conventional 2LiBH 4 + MgH 2 mixtures. During the hydrogen release from a mixture of 2LiBH 4 + nano-MgH 2 * at a hydrogen back-pressure of 0.4 MPa, MgB 2 is formed and three different plateaus of equilibrium were detected. The reaction pathway is changed at 360 °C for the 2LiBH 4 + MgH 2 system when the nano-MgH 2 * is used.
