Abstract
The microstructures of a dealuminated zeolite Y were observed with a t ransmission electron microscope (TEM) under a very low electron dose c ondition using a high sensitivity SSC camera for the purpose of elucid ating the formation mechanism of the mesopores, Mesopores were distrib uted three-dimensionally, They were closely related with the preexisti ng (111) twinning planes. The possibility of controlling the distribut ion of mesopores by controlling the distribution of twins during synth esis is also mentioned. (C) 1998 Academic Press.
