Ruthenium and oxygen
WebRuthenium phosphides are known to be highly stable and conductive materials. A new process was developed to prepare ruthenium phosphide catalysts for oxygen reduction in acid solutions. Several synthesis methods have been applied to form pure RuP and Ru 2 P as well as mixed phases of Ru and Ru x P ( x ≥ 1). Webfirst observation is that, for Ru films deposited at 3258C (Fig. 1), the growth rate increases from 0.3A˚ per cycle to 1A˚ percycleaftertheintroductionofO 2.Thismaybedueto the enhanced surface reactivity of the dissociatively adsorbed oxygen on the surface and the region just below the surface. The growth rate is relatively constant for O 2
