Zusammenfassung:Lack of Rh electrochemical data is discussed. Preparation of reproducible, preferred oriented, single crystals and their crystallographic analysis are described. The development of (610) planes during electrochemical faceting is discussed. Voltammograms of spherical and faceted crystals in 0.5M H sub 2 SO sub 4 between 0.03-0.3 V are presented and discussed. Voltammograms of Cu deposition on spherical and faceted single crystals are shown to be similar to those from Pt(100) and Rh(100) single crystals. 19 ref.--S.L.
