Fig. 5. (a) 13C NMR and 13C DEPT results obtained from reaction products of methane oxidation reaction over the 0.1% Fe/ZSM-5. (b) 2D 1H–13C HMQC NMR spectrum obtained from reaction products of methane oxidation reaction over the 0.1% Fe/ZSM-5. Reaction conditions: T = 50 °C, PCH4 = 30 bar (20% 13CH4), H2O2 = 0.5 M, V = 80 mL, catalyst = 0.3 g, rpm = 1500, t = 30 min.
