Abstract

Factors, both physical and chemical, influencing the pore-structure stability of high temperature catalysts and/or catalyst supports were discussed with a view to formulate strategies to design and develop high temperature catalyst supports. Factors influencing the sintering behavior and techniques to manipulate them are discussed. Chemical ways of modifying porosity reduction behavior can lead to changes in catalytic behavior. Therefore several physical techniques like control of packing and coordination by post precipitation treatment and nanocomposite formation, changing particle morphology and introducing rigid constraints were discussed.
