Synthesis and studies of structured support Ce0.75Zr0.25O2/θ-Al2O3/FeCrAl

Molten salt synthesis of CrMnFeNi alloy nanopowder passivated by TiOx–ZrOy shell used as a superior catalyst support in liquid-phase hydrogenation

“…The aluminum oxide surface shell formed by an initial oxidation treatment of the alloys protects from further inner oxidation, thus allowing FeCrAl alloy support to be available under high-temperature reaction conditions. 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 specic surface area (37.5 m 2 g −1 ) as catalyst support in CO methanation.…”
