摘要：

Acetaldehyde, acetaldehyde diethyl acetal (acetal), ethylene, hydrogen, methane, and carbon dioxide were produced from neat ethanol over TiO2 powder without metal in an Ar atmosphere under light irradiation. The yields of these products decreased in the above order. The following observation was obtained by using a filter which cut light at wavelengths below 390 nm. The yield of carbon dioxide was slightly decreased. The yield of acetaldehyde was greatly decreased at the initial irradiation, while it was slightly decreased with continuing of irradiation. The yield of acetal somewhat decreased, and that of ethylene, methane, and hydrogen roughly decreased to 1/2, 1/5, and 1/10, respectively.
