Characterization of Heated Platinum Filaments as a Source of Atomic Oxygen

摘要

Hot platinum filaments, for the production of atomic oxygen, have beencharacterized by two complementary techniques: line-of-sight gas phase analysis and surface trapping experiments using a gold substrate. It is demonstrated by both techniques that platinum is detected prior to detectable atomic oxygen production. This calls into question previous studies which have employed Pt as a thermal source of atomic oxygen for research purposes.
