N2 - In the first paragraph of the Discussion section, the potentials are incorrectly quoted with respect to SCE. These potentials should have been quoted with respect to SHE. The corrected paragraph reads as follows. Figure 3 shows that the active to passive transition for the Cu-Rh alloy compositions examined, occurs near 500 mV SHE, while the conventional Pourbaix diagram for elemental Rh predicts that oxidation will occur at ∼740 mV SHE [12]. However, Capon and Parsons have shown that in 1 M H2SO4 Rh oxidation initiates at a potential of 440 mV SHE [26]. Additionally, Hourani and Wieckowski showed that in 1 M HClO4 Rh oxidation initiates at about 430 mV SHE [27]. Ancillary LSV results obtained in our own laboratory show that in 0.1 M H2SO4, and at a sweep rate of 5 mVs-1, Rh oxidation/passivation initiates close to 500 mV SHE, which, other than slight variations resulting from alloying [15], is quite close to the occurrence of the active/passive transition observed for the Cu-Rh alloys.
