Organic additive free synthesis of mesoporous naoncrystalline NaA zeolite using high concentration inorganic precursors

Nanosize NaA zeolite particles of sizes ranging from 70 to 150 nm were hydrothermally synthesized from a high concentration inorganic precursor solution without using any organic additive. The nanocrystalline NaA zeolite particles have mesopores of pore diameter 2-20 nm. The mesoporous character was incurred by the intercrystalline and interparticular voids.
