“…To date, FeCrAl alloy supports have been used in several catalytic reactions involving methane oxidation, [3][4][5][6][7][8] selective catalytic reduction (SCR) of NO x , 9 CO oxidation, 10 methanation, 11 reforming, [12][13][14][15][16] and Fischer-Tropsch synthesis. 17 In our previous work, we used an intermetallic compound Ti 6 Si 7 Ni 16 with a high specic surface area (37.5 m 2 g −1 ) as catalyst support in CO methanation. 18 Similar to the FeCrAl alloy support, it was demonstrated by XPS measurements that the surface of Ti 6 Si 7 Ni 16 was passivated by a stable TiO x -SiO y oxidation shell to give Ti 6 Si 7 Ni 16 nanoparticles handled in air while maintaining the high specic surface area.…”
