The reactions of the aromatic oxygenates benzoic acid, benzaldehyde, benzyl alcohol, and phenol exhibit both strong similarities and strong differences as compared with their aliphatic analogues on the two polar surfaces of zinc oxide. The greatest similarities between aromatic and aliphatic compounds were observed on the (0001)-Zn polar surface. Benzyl alcohol and phenol reacted on the (0001)-Zn surface to form the corresponding surface alkoxide species. In sharp contrast to aliphatic alcohols, aldehydes, and carboxylic acids, toward which the (0001)-O polar surface is unreactive, the aromatic compounds reacted on the (0001)-O polar surface. These results further demonstrate the effects of surface crystallographic structure in determining the activity and reaction pathways on the metal oxide surfaces.
