Abstract
Provided is a scalable delamination of a SSZ-70 framework zeolite, without the need for sonication, which has been previously made difficult by the charged nature of the imidazolium structure-directing agents that are required for zeolite synthesis. The method comprises contacting a B-SSZ-70 zeolite precursor with a zinc source such as zinc nitrate and a fluoride source.
