By studying the information on cobalt supported alumina catalysts , , , ,  and , an interesting observation can be made. Let us recall, the difference between the selectivity profiles of nickel and cobalt towards 1-butanol (Ni) and ethyl acetate (Co) (Fig. 4). The Co3O4 spinel structure is known to contain tetrahedrally coordinated Co2+ and octahedrally coordinated Co3+. By connecting the observation to our results obtained with Co-16, dinoflagellates can be suggested that tetrahedral M2+ sites are responsible for the formation of ethyl acetate, whereas octahedral M2+ sites lead to 1-butanol.
