Catalytic data in aerobic oxidation of ethanol over the Au catalysts at (a) 120 and (b) 170°C. In the case of PVP-modified Au/SBA-15, the deactivated catalyst was treated with PVP again after reaction for 15 h at 120°C and 10h at 170°C and further used in the reaction. The acetaldehyde selectivities are over 98% at 120°C and over 95% at 170°C with acetic acid as by-product.
