Previously elusive , the all‐silica pure polymorph C of zeolite beta and a material enriched with polymorph B (see picture) are prepared by high‐throughput (HT) synthesis in the presence of a cationic organic structure‐directing agent (SDA). The presence of K + ions is essential for the formation of these materials; furthermore, a high ratio of OH − ions to silicon atoms favors the crystallization of polymorph C.
