| 摘 要： | 许多负载型催化剂的活性组分可在载体表面自发分散。当活性组分含量低于其分散阈值时,它在载体表面呈单层但非密置单层分散,逾此阈值时出现晶相。自发分散效应可以称为自发单层分散原理。对自发单层分散原理的实质等问题作了初步探讨。

| Abstract: | The active component of many supported catalysts will disperse spontaneously onto the surface of the carrier.When the active component content is less than the threshold of the active component dispersed on the surface of the carrier,it forms a monolayer,but not a close-packed monolayer distribution;above the threshold the crystalline active component appears.The effect of spontaneous dispersion may be characterized with principles of the spontaneous monolayer distribution.Nature of principles of the spontaneous monolayer distribution and sonephing like that is probed into initially. |

| Keywords: | active component dispersion dispersion thresholds principles of the spontaneous monolayer distribution nature |
