A study on the characteristics of CO oxidation at room temperature by metallic Pt

Various experiments and analysis were conducted in order to manufacture a catalyst that could very efficiently oxidize carbon monoxide at room temperature and also to identify the relevant factors influencing the oxidation reaction. Pt/TiO 2 catalyst can increase the oxidizing capability of CO at low temperature and room temperature by reduction. In FT-IR experiments, the catalyst that displayed excellent activity was capable of efficiently oxidizing CO to CO 2 using atmospheric oxygen. Based on the results of XPS analysis, we found that the reduced catalyst changed the platinum's oxidation value to Pt +2 and Pt +0. Through the O 2-reoxidation experiments, the catalyst, which consisted of non-stoichiometric platinum oxidized species, displayed an excellent ability to accept oxygen. In this study, the Pt/TiO 2 catalyst was able to very efficiently oxidize CO at low temperature and room temperature even with a minute quantity of platinum.
