Abstract
Provided is a surfactant-free, single-step synthesis of delaminated aluminosilicate zeolites. The process comprises the step of heating a borosilicate zeolite precursor in a metal salt solution, e.g., an aluminum nitrate solution, zinc nitrate solution or manganese nitrate solution. The delaminated aluminosilicate zeolite product is then recovered from the solution.
