Hydrogen storage properties of Ti-doped nanosized (similar to 20 nm) NaAlH4 supported on carbon nanofibers were affected by the stage at which Ti was introduced. When Ti was deposited first followed by NaAlH4, sorption properties were superior to the case where NaAlH4 was deposited first followed by NaAlH4. This was the result of both a smaller NaAlH4 particle size and the more extensive catalytic action of Ti in the former material.
