Thermal reduction of AlVMoO7

Temperature‐Programmed Reduction and Oxidation1A list of symbols used in the text is provided at the end of the chapter.

“…The Mo 6+ → Mo 4+ reduction step was reported to occur between 870 and 1070 K for pure bulk MoO 3 , whereas the Mo 4+ → Mo 0 reduction is observed between 1110 and 1180 K [45]. Several reduction peaks were reported in the TPR patterns of pure bulk V 2 O 5 between 900 and 1100 K at low H 2 concentrations.…”

“…These peaks were assigned to the stepwise V 2 O 5 → V 2 O 3 reduction process with V 6 O 13 , VO 2 and V 4 O 7 intermediates [12,46]. Interestingly, in the mixed V − Mo − O oxides the reactivity of each metallic element is reciprocally affected by a cooperative catalytic effect [45,48]. The final stable oxidation state was always V 3+ .…”
