用X射线光电子能谱(XPS)分析研究了铀金属在H_2及H_2-CO气氛中的表面反应以及温度和CO对氢化反应的影响。在25℃条件下由于痕量水汽的作用,铀金属表面主要发生氧化反应。在200℃时铀金属表面发生氢化反应,氢化反应随H_2通入量的增加而增加。
X-ray photoelectron spectroscopy (XPS) analysis of uranium metal surface reaction in H_2 and H_2-CO atmosphere and temperature and CO on the hydrogenation reaction. At 25 ℃ due to traces of water vapor, uranium metal surface oxidation occurs mainly. Hydrogenation reaction occurred on the surface of uranium metal at 200 ℃. The hydrogenation reaction increased with the increase of H 2 flux.
