摘要:The invention provides methods and compositions for precursors and for the synthesis of zeolites. The invention makes use of intimately homogeneous precursors which avoid the formation of a difficult to work with gel stage in zeolite formation. This allows for the synthesis of zeolite in a much shorter period of time and with much lower amounts of structure directing agents.
