M1 - PUBDB-2021-03147 SP - 11671 - 11681 PY - 2018 AB - To enhance the dehydrogenation/rehydrogenation kinetic behavior of the LiBH<sub>4</sub>–MgH<sub>2</sub> composite system, TiF<sub>4</sub> is used as an additive. The effect of this additive on the hydride composite system has been studied by means of laboratory and advanced synchrotron techniques. Investigations on the synthesis and mechanism upon hydrogen interaction show that the addition of TiF<sub>4</sub> to the LiBH<sub>4</sub>–MgH<sub>2</sub> composite system during the milling procedure leads to the in situ formation of well-distributed nanosized TiB<sub>2</sub> particles. These TiB<sub>2</sub> nanoparticles act as nucleation agents for the formation of MgB<sub>2</sub> upon dehydrogenation process of the hydride composite system. The effect of TiB<sub>2</sub> nanoparticles is maintained upon cycling.
