Fig. 4. Reversibility of RR2Ti properties under redox treatment.

Fig. 4

(A) In situ DRIFT spectra of CO adsorption over the RR2Ti-fresh sample following alternating pretreatment with 10 volume % H2/He at 500°C (for the first and third cycles) or 10 volume % O2/He at 400°C (for the second and fourth cycles) for 1 hour. (B) CO conversion at 80°C for the RR2Ti-fresh sample as a function of pretreatments described in (A). Reaction gas composition: 1 volume % CO + 1 volume % O2 balanced with He; gas flow rate, 33.3 ml/min; space velocity (SV), 64,452 ml gcat−1 hour−1.
