摘　　要：本文采用控制脉冲还原法研究了丙烯选择氧化催化剂Ｂｉ３Ｆ３ＭＯ２Ｏ１２在还原过程中的表面再构作用存在一个还原度阀值．对表面再构的机理提出了一些看法．Abstract By means of the controlled pulse reduction method,the surface reconstruction over the reduced Bi3FeMo2O12, was investigated.It had been found that the reconstruction behavior was quite temperature dependent.There was a threshold degree of reduction in relation to the reconstruction processes.The corresponding mechanism was proposed.
