We present a phase-transfer crystallization approach to the synthesis of ultrasmall (<100 nm) SAPO-34 crystallites. This method features porogen-free and tumbling crystallization in biphasic toluene-water media. The nanosized SAPO-34 catalyst has demonstrated prolonged catalysis lifetime (approximately 5 fold) and higher ethylene/propylene selectivity (by ca. 5%) for dimethylether-to-olefin conversion.
