(a) H2-TPR profiles of different redox catalysts ramping from 200 to 700 °C with a rate of 10 °C/min in a mixture of 10 vol% H2 in Ar (30 mL/min). C3H8-TPR mass spectra of (b) FeAl, (c) 1Mo9FeAl, (d) MoAl. The C3H8-TPR experiments were conducted from 200 to 600 °C with a rate of 10 °C/min in a mixture of 15 vol% C3H8 in He (10 mL/min). (e) In situ Raman spectra and (f) in situ XRD patterns of 1Mo9FeAl under the flow of 15 vol% C3H8 in He (20 mL/min) at different temperatures. The a.u. stands for arbitrary units.
