description The surface topography of amorphous metals useful as electrocatalysts in water electrolysis, denoted as G16 (Cos<sub>50</sub>Ni<sub>25</sub>Si<sub>15</sub>Bu<sub>10</sub>) and G14 (Fe<sub>60</sub>Co<sub>20</sub>Si<sub>10</sub>B<sub>10</sub>), are studied at the gm scale with a conventional SEM, and at the nm scale with the STM. Both untreated specimens as well as those employed as electrodes for a relatively prolonged time exhibit the same microstructure with amorphous and crystalline surface regions. The microcrystallite reduced size structure, probably involving a very compact structure, appears to be of the greatest importance concerning the electrocatalytic activity of these materials.
