2018-6-1 · Furthermore, the doping of 4 mol% of TiCl 3 with Na 3 AlH 6 with ball milling, releases a maximum of 1.7 wt% of hydrogen during hydrogenation process at 450 K and 2.5 MPa . Consequently, the TiCl 3 is expensive to produce kilogram scale quantity of NaAlH 4 , hence, TiF 3 is suggested to replace TiCl 3 as it is inexpensive.
