Objectives and Scope of This Review

Several key issues will be addressed including the following  

How do various experimental factors (i.e. reaction conditimis and catalyst jMoperties) affect the rate of sintering Of redispersion Under what coiditions do certain factc become rate controlling  

How do the i eparation and chemical/physical (xopoties of a catalyst affect its thermal stability For example, how do the choices of metal, suppmt, and prtMnoter affect thermal stability  

What are the principal fundamental mechanisms by which thermal degradation, sintering and redispersion of supported metals occur What factors determine which of these mechanisms predominates or controls the sintering process What do we leam from model catalyst studies regarding these mechanisms  

Of the experimental techniques available fcH- studying sintering phenmnena, which are most useful and how can they be utilized best What are their advantages and
