From: Regulating Au coverage for the direct oxidation of methane to methanol
a In-situ DRIFTS spectra of adsorbed CH4, O2 and H2 at 70 °C for Pd3Au1 NS in the range of 3700 to 800 cm−1. The signal of EPR spectrum of (b) radical species (•CH3, •OH, •OOH). c CH4-TPD-MS results of Pd, Pd3Au1 and Au NS. d PdxAuy NS-dependency of in-situ generation H2O2 productivity for 70 °C in O2 and H2 atmosphere. Each reaction was tested three times to obtain the error bars.
