Small‐Crystal SAPO‐34 Preparation by Regulating Precursor Mixing Temperature for Methanol‐to‐Olefins Conversion

Carbon and Hydrogen, EarlyView.
By tuning the initial mixing temperature from 0°C to 80°C, the crystal size of SAPO‐34 can be adjusted from micro to nanoscale, reflecting a shift from classical single‐crystal growth at low temperatures to non‐classical polycrystalline aggregation at high temperatures.
