a CO conversion plots under steady-state feed of “1% CO, 1% O2, N2 balance” and GHSV of 60,000 ml gcat−1 h−1. b Turnover frequencies of CO oxidation over Pt sites (TOFPt) measured at 80 °C and 100 °C with CO conversion below 20%. The error bars represent standard deviations. c Comparison of TOFPt between Pt/Sn0.2Ti0.8O2 and the Pt-based catalysts in reported references. d Long-term test of sulfur resistance in CO oxidation. Reaction conditions: reaction feed of 1% CO, 1% O2, 10% H2O, 100 ppm SO2, N2 balance; GHSV of 60,000 ml gcat−1 h−1; and reaction temperature of 240 °C.
