Exoemission accompanying the decomposition of methanol on zinc oxide

The electronic phenomena accompanying the adsorption and dehydrogenation of methanol on zinc oxide were studied using the method of exoemission of negative charges. Postemission excited from ZnO by an electron beam was found to be suppressed by the adsorption of methanol vapor, which exhibited electron acceptor properties. Subsequent heating to temperatures close to the temperature of the beginning of methanol decomposition increased the intensity of exoemission, which was evidence of the participation of emission centers (O^δ?) in dehydrogenation. A possible mechanism of methanol decomposition with the participation of surface V _s hole centers (O^δ?) of zinc oxide was suggested.
