摘要
YBa2Cu3O(6＋x)晶体上以O（1），O（2），O（3）和O（4）标记的氧原子的热稳定姓是不同的，O（1），O（2）和O（3），O（4）在特定条件下可以相互交换，由于这一独特的物理化学性质，使人们注意到它有可能成为一种氧化还原催化材料。
Thermal stability of oxygen atoms marked by O(1), O(2), O(3 ), O(4 ) in YBa2Cu3O6+x crystal are differ-ent, and O(1 ), O(2 ) and O(3), O(4 )can be exchanged into each other in special conditions. Because of the distintive physico-chemical property it has been awared that YBa2Cu3O6+ x may be a oxidation - reduction catalytic material.In this paper, thermal bchaviours of YBa2Cu3O6 + x in various (N2, O2, Ar + 5 % H2, Ar + 10% Co) have been examined and the activation energy of adsorption of YBa2Cu3O6+ x has been determined using CO as adsorbate,
