a The yield and selectivity of oxygenates from Rh/CeO2-com, Rh/CeO2 NWs, and SAs Rh-CeO2 NWs. Reaction conditions: PCH4: 0.5 MPa, H2O2: 20 mL (1 M), T: 50 °C, reaction time: 1 h, and catalyst weight: 10 mg. b DMC performance at different temperatures over SAs Rh-CeO2 NWs. Reaction conditions: PCH4: 0.5 MPa, H2O2: 20 mL (1 M), T: 30-90 °C, reaction time: 1 h, and catalyst weight: 10 mg. c DMC performance at different H2O2 concentrations over SAs Rh-CeO2 NWs. Reaction conditions: PCH4: 0.5 MPa, H2O2: 20 mL (0.1–1.5 M), T: 50 °C, reaction time: 1 h, and catalyst weight: 10 mg. d DMC performance at different CH4 partial pressure over SAs Rh-CeO2 NWs. Reaction conditions: PCH4: 0.5–3 MPa, H2O2: 20 mL (1 M), T: 50 °C, reaction time: 1 h, and catalyst weight: 10 mg. The error bars are defined as standard deviation of three experiments.
