The activity of rhenium as a hydrogen isotope equilibrium catalyst is inhibited by preadsorbed oxygen. The nearly linear decline in efficiency at 380 K and 980 K with increased oxygen coverage is matched by a similar decrease in the room temperature saturation uptake and initial sticking probability of hydrogen. In this rhenium closely resembles tungsten, and the conclusion is drawn that as far as hydrogen is concerned "patches" of high catalytic activity are not important. However, and unlike tungsten, the oxygen-saturated rhenium filament retained some catalytic and adsorptive capacity.
