Figure 5. Mechanism studies. (A) X-ray photoelectron spectra of MnOx/CeO2(0.05), acid-treated MnOx/CeO2(0.05) and CeO2. (B) Reaction rate and product selectivities in ethylbenzene oxidation over various catalysts. The triangles and stars represent the selectivities to 1-phenylethanol and acetophenone, respectively. (C) In-situ FTIR spectra of ethylbenzene adsorbed on
