The chemistry of nanostructured materials
... Both ITQ-7 and the polymorph C of zeolite beta contain D4R units and their syntheses were strongly affected by the presence of germanium. The effect of germanium in the synthesis of D4R-containing ... has also led to the synthesis of the pure polymorph C of zeolite beta (BEC) even in the absence of the fluoride medium that is generally believed to assist in th...
