VALENCE BAND SPECTRA OF ACETYLENIC MOIETIES ON ZINC-OXIDE - ACETYLIDE VERSUS PROPARGYL FORMATION Academic Article

abstract

• Acetylene adsorbs dissociatively on the ZnO(0001) surface, as on other metal oxides, to form acetylide intermediates, CCH. Propyne also dissociates via surface acid-base reactions; however, potential adsorbates include methylacetylide (CH3CC) and propargyl (CH2CCH) species. Ultraviolet photoelectron spectra (UPS) of the adsorbed intermediates formed from propyne and allene on the ZnO(0001) surface demonstrate that both react to form propargyl intermediates. UPS also provide useful fingerprints of -bonded acetylides on both metal and metal oxide surfaces. 1990 American Chemical Society.
