Direct, real-space determination of intergrowths in ZSM-5/ZSM-11 catalysts
Abstract
The performance of shape-selective catalysts is thought to be a function of the nature of the intergrowths present in the structure, but hitherto no direct methods of identifying isolated or ordered intergrowths have been available; high resolution electron microscopy is shown to be capable of solving such problems, and in particular single strips of ZSM-11 may be directly identified in ZSM-5.
