Reaction gas composition: 1.6 volume % CO, 1 volume % O2, 0.01 volume % propene, 0.0051 volume % toluene, and 10 volume % water balanced with He. For RR2Ti-H400: 40.5 mg of sample diluted with 120 mg of SiO2 powder; gas flow rate, 33.3 ml/min; SV, 49,000 ml gcat−1 min−1. For RR2Ti-fresh: 15.9 mg of sample diluted with 60 mg of SiO2 powder; gas flow rate, 33.3 ml/min; SV, 127,000 ml gcat−1 min−1.
