a Light-off curves of the as-prepared catalysts (reaction conditions: ca. 200 mg catalyst, [C2H6] = 3000 ppm, Q = 200 mL min-1 and WHSV = 60,000 h-1). b corresponding Arrhenius plots. c specific ethane conversion rate at 200 °C. d a correlation of the fitted peak area of oxygen species from O2-TPD analysis with C2H6 oxidation rate at 200 °C. e comparation of ethane conversion rate at T50 with other catalysts reported in the literature (see Table S9 for details). f cyclic thermal stability test of MnCoOx−0.5 catalyst. g cyclic hydrothermal stability test of MnCoOx-0.5 catalyst (reaction conditions: ca. 200 mg catalyst, [C2H6] = 3000 ppm, Q = 600 mL min-1, WHSV = 180,000 h-1 w/o and w/ 5 vol% H2O, respectively). h long-term scale up stability tests by 1 wt% MnCoOx-0.5 coated on micro-monolith substrate for 1000 h (reaction conditions: 350 °C, [C2H6] = 1300 ppm, Q = 10,000 mL min-1, and GHSV = 6000 h-1, w/ and w/o 5 vol% of H2O).
