“…Various studies have been carried out on Ti doped and bare alanates [11][12][13][14][15] for analyzing the location and role of the Ti catalyst. However, these studies have not been able to elucidate the said aspects of the catalyst Ti [2][3][4][5][6][7][8][9][10][16][17][18][19][20][21][22][23][24][25][28][29][30][31]. Besides transition metals Ti, Zr and Fe, carbon nanotubes have also been found to enhance hydrogen desorption in NaAlH 4 [24,25].…”
