Abstract:

A series of alumina-pillared layered titanoniobates with different interlayer distances were first prepared by using a step-wise exchange process. The effect of reaction conditions such as reaction temperature, reaction time, ageing time of pillaring agent, and molar ratio of two reactans was exmained. The resultat pillazed smples have a range of interlayer distances from 1.23 nm to 1.38 nm, and are thermostable over 500 ℃.
