Abstract

High resolution transmission electron microscopy has been used to examine the crystallites in γ-Al2O3 and η-Al2O3. γ-Al2O3 has been found to be nearly hexagonally shaped crystallites whose identity distances and angles of fringe patterns indicate that (110) planes are preferentially exposed. η-Al2O3 showed preferentially exposed surfaces of (100), (110) and super imposed (111)/(211). This information is valuable to the catalyst researcher trying to model the surfaces of these two supports.
