摘要：

High-silica erionite (ERI) zeolites are conventionally synthesised via a so-called charge density mismatch (CDM) approach, and a typical synthesis takes several days to complete. We herein demonstrate an ultrafast route to synthesise high-silica erionite zeolites in as short as 2 h at 210 degrees C. The fast-synthesised ERI has been proved to show higher hydrothermal stability compared with the conventionally synthesised product.
