Except for support effects, structure sensitivity has usually appeared in one of two aspects, variation of rate with svirface crystal face or with particle size. In ICC 1 Gwathmey reported in one of the first experiments with single crystal faces that different faces machined fi om Ni single crystal spheres catalyzed the hydrogenation of ethylene at different rates (ICC 1 paper 5).

Correlations of various kinds between the geometry of a solid surface and catalytic activity have been proposed in the past in varying degrees by such workers as Langmuir (1), Adkins (2), Burk (3), Balandin (4), Beeck (5), Rideal (6), Maxted (7), and Gwathmey (8). A first guess would suggest that a particularly favorable fit of the adsorbed molecules on the crystal array of the surfaces, not necessarily a one-to-one correspondence, would promote reaction. There have been few cases, however, in which a deliberate effort... 

Leidheiser and Gwathmey (8) found that, when a spherical nickel crystal was exposed to an atmosphere of carbon monoxide at 550°, carbon deposited, as shown in Fig. 13, in the (111) region but not in the (100) or...
