Laser Stimulated Oxidative Coupling of Ethanol

Revised Date: 31 December 1994

The oxidative coupling of ethanol stimulated by CO₂ laser on the surface of Cu₂ (PO₄)(OH) and Pb₃(PO₄)₂ has been studied using XRD and IR techniques. The results showed that the distribution of reaction products depends strongly on the chemisorption types of ethanol:1,4-butanediol was formed via the methyl-adsorbed ethanol molecules, while the hydroxyl-adsorbed one gave to ethene. The vibrational structures of the surface of solid meterials are the basic factor affecting the efficiency of laser photon energy. The higher efficiency of laser photon energy in the case of libethenite appeared due to the greater differ-ence in frequecies between P=O and O-Cu-O bonds.
