本文用XPS研究了银表面上氧的吸附。结果表明,在室温低压下,氧在银表面上存在各种吸附态,它们随氧吸附量增长过程而变化。金属银是乙烯制环氧乙烷和醇制醛的有效催化剂
In this paper, XPS was used to study the adsorption of oxygen on silver surface. The results show that there are various adsorption states of oxygen on the surface of silver at room temperature and low pressure, which change with the increase of oxygen adsorption capacity. Metallic silver is an effective catalyst for the production of ethylene oxide and alcohol aldehydes
